A reader shares a report from MIT Technology Review: Astronomers have just released the highest-resolution image of the sun. Taken by the Daniel K. Inouye Solar Telescope in Maui, it gives us an unprecedented view of our nearest star and brings us closer to solving several long-standing mysteries. The new image demonstrates the telescope's potential power. It shows off a surface that's divided up into discrete, Texas-size cells, like cracked sections in the desert soil. You can see plasma oozing off the surface, rising into the air before sinking back into darker lanes.

"We have now seen the smallest details on the largest object in our solar system," says Thomas Rimmele, the director of DKIST. The new image was taken December 10, when the telescope achieved first light. It is still technically under construction, with three more instruments set to come online. When formal observations begin in July, DKIST, with its 13-foot mirror, will be the most powerful solar telescope in the world. Located on Haleakala (the tallest summit on Maui), the telescope will be able to observe structures on the surface of the sun as small as 18.5 miles (30 kilometers). This resolution is over five times better than that of DKIST's predecessor, the Richard B. Dunn Solar Telescope in New Mexico.

Id software has released a new trailer for their upcoming Doom sequel set on a demon-infested planet Earth in the year 2151. And GameSpot has uploaded a 10-minute clip of gameplay while Collider released 15 minutes.

Collider writes: Doom Eternal takes everything that was gloriously batshit about Doom 2016, throws it in a Lamborghini full of Slayer albums and catapults it into the sun. This game is out of its goddamn mind in the best possible way, and I literally cannot wait to get my hands on the full version... The Fortress of Doom is massive. I wasn't able to access every area, and could only guess at the function of some of the areas I did see. One section had the original Doom Marine costume on display in a glass case, and the game's director, Hugo Martin confirmed that the skin is an unlockable. Moreover, he indicated that there are several unlockable player skins in the game, including one he was clearly excited about but couldn't reveal, saying that it was still in the licensing approval stage...

Doom Eternal, like its predecessor, is a fast game, pitting you against hordes of powerful enemies that force you to constantly be on the move and quick-swapping weapons to inflict maximum damage while avoiding death. You have a few tools at your disposal to earn guaranteed life, ammo, and armor, which are the over-the-top glory kills, the terrifying chainsaw, and the brand-new flame belcher respectively. Glory kills are special instant-death maneuvers you can unleash on enemies after staggering them, and the addition of a retractable arm blade has heightened the graphic absurdity of them to such a degree that I was giggling like an idiot every time I pulled one off.

I spent the next three hours murdering my way across three massive levels that were incredibly varied in terms of design, beginning in a blasted post-apocalyptic city, then moving to a vast overgrown temple, and finally ending up in a heavily-fortified arctic base... Each stage had a completely different feel -- the city was very ground-based, with dark subway tunnels and skeletal office buildings. The temple was spread out across what felt like miles, with an unexpected amount of verticality and traversal thanks to the new climbing mechanic. Yep, Doom Guy can now cling to certain walls, as well as swing from poles to extend his jump and gain access to distant ledges. The climbing controls are a bit funky, like Spider-Man with a rotator cuff injury, but the traversal puzzles are fun and satisfying, and allow for some truly massive environments...

Martin promised that players will continue to be introduced to new enemies and environments right up until the end of the 22+ hour campaign. He describes Doom Eternal as a thinking person's action game, and that the team's goal was to create a combat puzzle worth your time.
DOOM Eternal is scheduled to be released on March 20th.

The future of the next 46 billion devices. From a report: "What do you think is the biggest hardware business at Microsoft?" asked Microsoft CEO Satya Nadella last week during a private media event. "Xbox," answered a reporter who had been quizzing Nadella on how the company's hardware products like Surface and Xbox fit into the broader ambitions of Microsoft. "No, it's our cloud," fired back Nadella, explaining how Microsoft is building everything from the data centers to the servers and network stack that fit inside. As the reporter pushed further on the hardware point, a frequent question given Microsoft's focus on the cloud, Nadella provided us with the best vision for the modern Microsoft that moves well beyond the billion-or-so Windows users that previously defined the company.

"The way I look at it is Windows is the billion user install base of ours. We continue to add a couple of hundred million PCs every year, and we want to serve that in a super good way," explained Nadella. "The thing that we also want to think about is the broader context. We don't want to be defined by just what we achieved. We look at if there's going to be 50 billion endpoints. Windows with its billion is good, Android with its 2 billion is good, iOS with its billion is good -- but there is 46 billion more. So let's go and look at what that 46 billion plus 4 [billion] looks like, and define a strategy for that, and then have everything have a place under the sun."

Alan Buis of NASA's Jet Propulsion Laboratory, writes: There's an old saying that "the proof is in the pudding," meaning that you can only truly gauge the quality of something once it's been put to a test. Such is the case with climate models: mathematical computer simulations of the various factors that interact to affect Earth's climate, such as our atmosphere, ocean, ice, land surface and the Sun. For decades, people have legitimately wondered how well climate models perform in predicting future climate conditions. Based on solid physics and the best understanding of the Earth system available, they skillfully reproduce observed data. Nevertheless, they have a wide response to increasing carbon dioxide levels, and many uncertainties remain in the details. The hallmark of good science, however, is the ability to make testable predictions, and climate models have been making predictions since the 1970s. How reliable have they been? Now a new evaluation of global climate models used to project Earth's future global average surface temperatures over the past half-century answers that question: most of the models have been quite accurate.

In a study accepted for publication in the journal Geophysical Research Letters, a research team led by Zeke Hausfather of the University of California, Berkeley, conducted a systematic evaluation of the performance of past climate models. The team compared 17 increasingly sophisticated model projections of global average temperature developed between 1970 and 2007, including some originally developed by NASA, with actual changes in global temperature observed through the end of 2017. The observational temperature data came from multiple sources, including NASA's Goddard Institute for Space Studies Surface Temperature Analysis (GISTEMP) time series, an estimate of global surface temperature change. The results: 10 of the model projections closely matched observations. Moreover, after accounting for differences between modeled and actual changes in atmospheric carbon dioxide and other factors that drive climate, the number increased to 14. The authors found no evidence that the climate models evaluated either systematically overestimated or underestimated warming over the period of their projections.

fahrbot-bot shares a report from the BBC: Scientists analyzing a meteorite have discovered the oldest material known to exist on Earth. They found dust grains within the space rock -- which fell to Earth in the 1960s -- that are as much as 7.5 billion years old. The oldest of the dust grains were formed in stars that roared to life long before our Solar System was born. A team of researchers has described the result in the journal Proceedings of the National Academy of Sciences.

The team from the U.S. and Switzerland analyzed 40 pre-solar grains contained in a portion of the Murchison meteorite, that fell in Australia in 1969. Based on how many cosmic rays had interacted with the grains, most had to be 4.6-4.9 billion years old. For comparison, the Sun is 4.6 billion years old and the Earth is 4.5 billion. However, the oldest yielded a date of around 7.5 billion years old. Previously, the oldest pre-solar grain dated with neon isotopes was around 5.5 billion years old.

"NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size planet in its star's habitable zone, the range of distances where conditions may be just right to allow the presence of liquid water on the surface," reports NASA's Goddard Space Flight Center: Scientists confirmed the find, called TOI 700 d, using NASA's Spitzer Space Telescope and have modeled the planet's potential environments to help inform future observations.

TOI 700 is a small, cool M dwarf star located just over 100 light-years away in the southern constellation Dorado. It's roughly 40 of the Sun's mass and size and about half its surface temperature. The star appears in 11 of the 13 sectors TESS observed during the mission's first year, and scientists caught multiple transits by its three planets. The innermost planet, called TOI 700 b, is almost exactly Earth-size, is probably rocky and completes an orbit every 10 days. The middle planet, TOI 700 c, is 2.6 times larger than Earth -- between the sizes of Earth and Neptune -- orbits every 16 days and is likely a gas-dominated world. TOI 700 d, the outermost known planet in the system and the only one in the habitable zone, measures 20 larger than Earth, orbits every 37 days and receives from its star 86% of the energy that the Sun provides to Earth.

All of the planets are thought to be tidally locked to their star, which means they rotate once per orbit so that one side is constantly bathed in daylight... While the exact conditions on TOI 700 d are unknown, scientists used current information, like the planet's size and the type of star it orbits, and modeled 20 potential environments for TOI 700 d to gauge if any version would result in surface temperatures and pressures suitable for habitability.

One simulation included an ocean-covered TOI 700 d with a dense, carbon-dioxide-dominated atmosphere similar to what scientists suspect surrounded Mars when it was young. The model atmosphere contains a deep layer of clouds on the star-facing side. Another model depicts TOI 700 d as a cloudless, all-land version of modern Earth, where winds flow away from the night side of the planet and converge on the point directly facing the star.

"Linux kernel head Linus Torvalds has warned engineers against adding a module for the ZFS filesystem that was designed by Sun Microsystems -- and now owned by Oracle -- due to licensing issues," reports ZDNet: As reported by Phoronix, Torvalds has warned kernel developers against using ZFS on Linux, an implementation of OpenZFS, and refuses to merge any ZFS code until Oracle changes the open-source license it uses.

ZFS has long been licensed under Sun's Common Development and Distribution License as opposed to the Linux kernel, which is licensed under GNU General Public License (GPL). Torvalds aired his opinion on the matter in response to a developer who argued that a recent kernel change "broke an important third-party module: ZFS". The Linux kernel creator says he refuses to merge the ZFS module into the kernel because he can't risk a lawsuit from "litigious" Oracle -- which is still trying to sue Google for copyright violations over its use of Java APIs in Android -- and Torvalds won't do so until Oracle founder Larry Ellison signs off on its use in the Linux kernel.

"If somebody adds a kernel module like ZFS, they are on their own. I can't maintain it and I cannot be bound by other people's kernel changes," explained Torvalds. "And honestly, there is no way I can merge any of the ZFS efforts until I get an official letter from Oracle that is signed by their main legal counsel or preferably by Larry Ellison himself that says that yes, it's OK to do so and treat the end result as GPL'd," Torvalds continued.

"Other people think it can be OK to merge ZFS code into the kernel and that the module interface makes it OK, and that's their decision. But considering Oracle's litigious nature, and the questions over licensing, there's no way I can feel safe in ever doing so."

The Pacific nation of Palau has become the first country to ban sun cream that is harmful to corals and sea life. From a report: From Wednesday, sun cream that includes common ingredients, including oxybenzone, is not allowed to be worn or sold in the country. Palau's President Tommy Remengesau said: "We have to live and respect the environment because the environment is the nest of life." The island nation markets itself as a "pristine paradise" for divers. A lagoon in Palau's Rock Islands is a Unesco World Heritage site. The country has a population of around 20,000 dotted across hundreds of islands. The ban -- which was announced in 2018 - prohibits sun cream containing any of 10 ingredients. The list includes oxybenzone and octinoxate, which absorb ultraviolet light. The International Coral Reef Foundation said the banned chemicals were "known environmental pollutants -- most of them are... incredibly toxic to juvenile stages of many wildlife species."

India has approved its third lunar mission months after its last one failed to successfully land on the moon, its space agency said on Wednesday, the latest effort in its ambitions to become a low-cost space power. From a report: The Chandrayaan-3 mission will have a lander and a rover, but not an orbiter, Indian Space Research Organisation (ISRO) Chairman K. Sivan told reporters at its headquarters in Bengaluru, according to an official telecast. The Chandrayaan-2 mission in September successfully deployed a lunar orbiter that relays scientific data back to earth, but was unable to place a rover on the lunar surface after a "hard" landing. That mission had aimed to land on the south pole of the moon, where no other lunar mission had gone before. The region is believed to contain water as craters in the region are largely unaffected by the high temperatures of the sun.

Thousands of skywatchers gathered across parts of the Middle East and Asia on Thursday to glimpse the sun forming a ring of fire around the moon in a rare annular solar eclipse. From a report: An annular eclipse occurs when the moon covers the sun's center but leaves its outer edges visible to form a ring. Thursday's was visible in Saudi Arabia as well as Singapore, India, Sri Lanka and Indonesia.

The US government has for the first time authorized funding to research geoengineering, the idea that we could counteract climate change by reflecting more of the sun's heat away from the planet. An anonymous reader writes: The $1.4 trillion spending bills that Congress passed last week included a little-noticed provision setting aside at least $4 million for the National Oceanic and Atmospheric Administration to conduct stratospheric monitoring and research efforts. The primary aims of the program would include improving our basic understanding of stratospheric chemistry, and assessing the potential effects and risks of geoengineering. But it's controversial: There are concerns that using such tools could have dangerous environmental side effects, and that even suggesting them as solutions could ease pressure to cut the greenhouse-gas emissions driving climate change.

"China is about to start operation on its 'artificial sun' -- a nuclear fusion device that produces energy by replicating the reactions that take place at the center of the sun," writes Newsweek.

schwit1 shared their report: If successful, the device could edge scientists closer to achieving the ultimate goal of nuclear fusion: near limitless, cheap clean energy.

The device, called HL-2M Tokamak, is part of the nation's Experimental Advanced Superconducting Tokamak project, which has been running since 2006. In March, an official from the China National Nuclear Corporation announced it would complete building HL-2M by the end of the year. The coil system was installed in June and since then, work on HL-2M has gone "smoothly," the Xinhua News Agency reported in November. Duan Xuru, head of the Southwestern Institute of Physics, which is part of the corporation, announced the device will become operational in 2020 at the 2019 China Fusion Energy Conference, the state news agency said.

He told attendees how the new device will achieve temperatures of over 200 million degrees Celsius. That's about 13 times hotter than the center of the sun. Previous devices developed for the artificial sun experiment reached 100 million degrees Celsius, a breakthrough that was announced in November last year.

The Tow Center for Digital Journalism at Columbia's Graduate School of Journalism reports: An increasingly popular tactic challenges conventional wisdom on the spread of electoral disinformation: the creation of partisan outlets masquerading as local news organizations. An investigation by the Tow Center for Digital Journalism at Columbia Journalism School has discovered at least 450 websites in a network of local and business news organizations, each distributing thousands of algorithmically generated articles and a smaller number of reported stories. Of the 450 sites we discovered, at least 189 were set up as local news networks across ten states within the last twelve months by an organization called Metric Media. Titles like the East Michigan News, Hickory Sun, and Grand Canyon Times have appeared on the web ahead of the 2020 election. These networks of sites can be used in a variety of ways: as 'stage setting' for events, focusing attention on issues such as voter fraud and energy pricing, providing the appearance of neutrality for partisan issues, or to gather data from users that can then be used for political targeting.

On October 20, the Lansing State Journal first broke the story of the network's existence. About three dozen local news sites, owned by Metric Media, had appeared in Michigan. Further reporting by the Michigan Daily, the Guardian and the New York Times identified yet more sites. Ultimately, previous reporting has identified around 200 of these sites. Our analysis suggests that there are at least twice that number of publications across a number of related networks, of which Metric Media is just one component. Over a two-week period starting November 26, we tapped into the RSS feeds of these 189 Metric Media sites, all of which were we found that were created this year, and found over fifteen thousand unique stories had been published (over fifty thousand when aggregated across the sites), but only about a hundred titles had the bylines of human reporters. The rest cited automated services or press releases.

An anonymous reader quotes a report from Bloomberg: A nuclear fusion start-up backed by billionaire Jeff Bezos raised more than $100 million to help design and build a demonstration power plant. The company lined up $65 million in Series E financing led by Singapore's Temasek Holdings Pte, and is getting another $38 million from Canada's Strategic Innovation Fund, General Fusion Inc. said in a statement Monday. It's now attracted more than $200 million in financing.

Canada-based General Fusion is one of about two dozen companies seeking to commercialize nuclear fusion technology. It relies on the same process that powers stars, generating huge amounts of energy by fusing small atoms into larger ones. While it holds out the promise of cheap, carbon-free energy, researchers have been working for decades to overcome significant technical hurdles. Firms pursuing such designs are hoping they can start generating power sooner than the 35-nation, $25 billion Tokamak fusion reactor known as ITER. Collaborators on that facility -- the largest research project in history -- have been laboring on a gigantic demonstration reactor in France since 2010.

California now has one million solar roofs, representing about 14% of all renewable power generated in the state. But solar advocates "said the milestone has come despite escalating efforts by utilities to undermine rooftop solar installations," according to the San Diego Union-Tribune.

"They said those attacks include everything from hefty fees on ratepayers to calling for dramatic cuts to the credits residents receive for generating energy from the sun." "We will seek sensible solutions that continue to encourage solar power but don't adversely affect working families who can't afford solar systems," said SDG&E spokesman Wes Jones. Advocates have said that utilities are exaggerating the challenges that rooftop solar creates and downplaying the value it adds to the overall system. "They trot out this cost-shifting argument that looks on the face of it like they care about equity, but really the opposite is true," said Dave Rosenfeld, executive director of the Solar Rights Alliance, a new consumer rights group funded by ratepayers and rooftop solar companies. "If you do the numbers right, solar is contributing to a reduction in the cost of operating the electricity grid now and in the future..."

Power providers specifically argued that homeowners with solar panels weren't paying their fair share of the costs associated with building, maintaining and operating the state's extensive energy grid as well as fees associated with state-mandated energy efficiency and other programs. Over the last century, the price tag of expanding the state's electrical infrastructure to service remote communities and hook up to new power plants has largely been socialized, spread evenly over the customer base through rate increases approved by the utilities commission. All of those costs get baked into electric bills, but because the net metering program credits rooftop solar at the retail rate, rather than the wholesale rate, utilities say folks with solar panels have been getting something of a free ride. Utility officials have said that as a result they have had to shift those costs onto customers without solar. "Through the existing net energy metering policy, rooftop solar customers are subsidized by customers without solar rooftops," said Ari Vanrenen, spokesman for PG&E....

Advocates of rooftop solar strongly disagreed with this assessment. They said the technology, especially when paired with batteries, will eventually bring down the cost of electricity for everyone -- specifically by reducing the need for costly upgrades to the power grid. They argued that investor-owned utilities oppose rooftop solar because it will eventually curb the growth model that companies have long used to reward shareholders and pay out large salaries. SDG&E and others have an incentive to build solar out in the desert because it requires building long power lines, which are then used to justify rate hikes, said Bill Powers, a prominent electrical engineering consultant and consumer advocate.
The article also points out that some California utilities have raised their minimum bill -- with one specifically saying they were doing it to target solar customers, and another launching a new $65-a-month fee on any customer who installs solar panels.

The Bad Astronomer writes: Last week, scientists announced the discovery of a stellar-mass black hole with 70 times the Sun's mass, far heftier than theory predicts they can get. Within days, though, four separate papers have come out casting extreme doubt on the claim. They show that the data wasn't processed correctly, and that the black hole is closer to Earth than first assumed, which changes the calculations and makes it a more normal 5 - 20 solar mass object.

"Astronomers have found the biggest black hole ever measured -- it's 40 billion times the sun's mass, or roughly two-thirds the mass of all stars in the Milky Way," writes Astronomy.com.

A reader shares their report: The gargantuan black hole lurks in a galaxy that's supermassive itself and probably formed from the collisions of at least eight smaller galaxies.

Holm 15A is a huge elliptical galaxy at the center of a cluster of galaxies called Abell 85... When two spiral galaxies -- like our Milky Way and the nearby Andromeda Galaxy -- collide, they can merge and form an elliptical galaxy. In crowded environments like galaxy clusters, these elliptical galaxies can collide and merge again to form an even larger elliptical galaxy. Their central black holes combine as well and make larger black holes, which can kick huge swaths of nearby stars out to the edges of the newly formed galaxy. The resulting extra-large elliptical galaxy usually doesn't have much gas from which to form new stars, so its center looks pretty bare after its black hole kicks out nearby stars. Astronomers call these huge elliptical galaxies with faint centers "cored galaxies." Massive cored galaxies often sit in the centers of galaxy clusters.

The authors of the new study found that Holm 15A, the enormous galaxy at the center of its home galaxy cluster, must have formed from yet another merger of two already-huge cored elliptical galaxies. That would mean Holm 15A probably formed from the combination of eight smaller spiral galaxies over billions of years... This series of mergers also created the black hole in its center, a monster about as big as our solar system but with the mass of 40 billion suns.
One of the study's authors says their discovery finally confirms the current theory about how quasars work.

In August of last year, NASA sent a spacecraft hurtling toward the inner Solar System, with the aim of getting some answers about the mysterious star at the center of our cosmic neighborhood. Now more than a year later, that tiny robot has started to decode some of the mysteries surrounding our Sun's behavior, after venturing closer to our parent star than any human-made object has before. From a report: That spacecraft is NASA's Parker Solar Probe, a car-sized vehicle designed to withstand temperatures of more then 2,500 degrees Fahrenheit. Its various instruments are protected by an extra hardy heat shield, designed to keep the spacecraft relatively cool as it gets near our balmy host star. Already, the Parker Solar Probe has gotten up close and personal with the Sun, coming within 15 million miles of the star -- closer than Mercury and any other spacecraft sent to the Sun before. "We got into the record books already," Adam Szabo, the mission scientist at NASA Goddard Space Flight Center for Parker Solar Probe, tells The Verge.

Before the spacecraft's launch, researchers were particularly interested in learning more about what's coming out of the Sun. Energetic particles and plasma are continuously streaming from the Sun at all times -- a phenomena that's been dubbed solar wind. This highly energized material makes its way to Earth, causing the dazzling display of the aurora borealis. If we get too much of this stuff, it can sometimes muck up our spacecraft in orbit and even mess with our electric grid. There's still a lot we don't know about solar wind, such as what is accelerating this material so much that it can break free from the Sun. Learning the origins of the wind could help us better predict how it will impact us here on Earth.

An anonymous reader shares a report: Astronomers think our home galaxy -- the Milky Way -- is practically bursting with black holes, with estimates of up to 100 million of the invisible beasts hiding across the galactic neighborhood. It was generally assumed these black holes could reach a mass of up to 20 times that of the sun, but the discovery of a "monster" black hole, with about 70 times the mass of the sun, has surprised Chinese astronomers. In a new study, published in the journal Nature on Nov. 27, a research team from the Chinese Academy of Sciences peered across the galaxy with the Large sky Area Multi-Object fibre Spectroscopic Telescope (Lamost), based at Xinglong Observatory in China. Black holes don't emit light, so astronomers have to get crafty when they go hunting for them.

Usually, this involves looking for signs a black hole is feasting on a nearby star or the gas and dust that swirls around them. If the black hole isn't feasting and if it isn't surrounded by bright gas and dust, it becomes a little trickier to locate. But, using Lamost, the team examined the movement of stars across the sky, searching for those that seemed to be orbiting an invisible object. Follow-up observations with telescopes in Spain and the US helped the researchers discover a star about eight times bigger than the sun. Intriguingly, it was orbiting a "dark companion": The monster black hole, dubbed LB-1. "Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution," said Liu Jifeng, astronomer at the National Astronomical Observatory of China and first author of the study, in a press release. "LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation."

Billionaire venture capitalist Vinod Khosla's long-running fight to block public access to a stretch of Pacific Ocean beach adjacent to his property got new life thanks to an appeals court ruling that could make it harder for surfers and sun seekers to get to the crescent-shaped cove an hour south of San Francisco. From a report: The beach had been open to the public for decades before Khosla bought the 89-acre property in 2008 for $32.5 million and shut off the lone road leading there. Many thought Khosla had hit a dead end last year when the U.S. Supreme Court refused to take up his cause, but the ruling Monday breathed life into it, finding the prior owners' willingness to let beach goers use the road didn't amount to a "public dedication" because they collected fees for parking. That strengthens Khosla's position if and when he obtains a permit from the California Coastal Commission to restrict the hours when a gate at the top of the road is open. The Friends of Martin's Beach, which has been sparring with the billionaire for years, wanted the court to find there was a long-established precedent for keeping the road open. Instead, the three-judge panel upheld a trial judge's ruling in Khosla's favor, finding there was substantial evidence that the previous owners didn't intend to dedicate the road for public use because they charged fees.
