A new map of the universe displays for the first time the span of the entire known cosmos with pinpoint accuracy and sweeping beauty. Phys.Org reports: Created by Johns Hopkins University astronomers with data mined over two decades by the Sloan Digital Sky Survey, the map allows the public to experience data previously only accessible to scientists. The interactive map, which depicts the actual position and real colors of 200,000 galaxies, is available online, where it can also be downloaded for free.

The Sloan Digital Sky Survey is a pioneering effort to capture the night sky through a telescope based in New Mexico. Night after night for years, the telescope aimed at slightly different locations to capture this unusually broad perspective. The map, which [map creator Brice Manard] assembled with the help of former Johns Hopkins computer science student Nikita Shtarkman, visualizes a slice of the universe, or about 200,000 galaxies — each dot on the map is a galaxy and each galaxy contains billions of stars and planets. The Milky Way is simply one of these dots, the one at the very bottom of the map.

The expansion of the universe contributes to make this map even more colorful. The farther an object, the redder it appears. The top of the map reveals the first flash of radiation emitted soon after the Big Bang, 13.7 billion years ago. “In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets,” Manard says. “We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale.” For those interested, Johns Hopkins University published a video about the map on YouTube.

According to documents recently declassified by the National Geospatial-Intelligence Agency (NGA), former President Donald Trump posted a classified satellite image of a failed rocket launch in Iran on Twitter in 2019. NPR reports: Now, three years after Trump’s tweet, the National Geospatial-Intelligence Agency (NGA) has formally declassified the original image. The declassification, which came as the result of a Freedom of Information Act request by NPR, followed a grueling Pentagon-wide review to determine whether the briefing slide it came from could be shared with the public. Many details on the original image remain redacted — a clear sign that Trump was sharing some of the U.S. government’s most prized intelligence on social media, says Steven Aftergood, specialist in secrecy and classification at the Federation of American Scientists. “He was getting literally a bird’s eye view of some of the most sensitive US intelligence on Iran,” he says. “And the first thing he seemed to want to do was to blurt it out over Twitter.” “[A]erospace experts determined the photo was taken by a classified spacecraft called USA 224, believed to be a multibillion-dollar KH-11 reconnaissance aircraft,” adds Gizmodo. “The spacecraft is similar to the Hubble Telescope, but instead of getting a closer look at the stars, it views the Earth’s surface.”

An anonymous reader quotes a report from Phys.Org: Say hello to ronnagrams and quettameters: International scientists gathered in France voted on Friday for new metric prefixes to express the world’s largest and smallest measurements, prompted by an ever-growing amount of data. It marks the first time in more than three decades that new prefixes have been added to the International System of Units (SI), the agreed global standard for the metric system. Joining the ranks of well-known prefixes like kilo and milli are ronna and quetta for the largest numbers — and ronto and quecto for the smallest.

The change was voted on by scientists and government representatives from across the world attending the 27th General Conference on Weights and Measures, which governs the SI and meets roughly every four years at Versailles Palace, west of Paris. The prefixes make it easier to express large amounts — for example, always referring to a kilometer as 1,000 meters or a millimeter as one thousandth of a meter would quickly become cumbersome. Since the SI was established in 1960, scientific need has led to a growing number of prefixes. The last time was in 1991, when chemists wanting to express vast molecular quantities spurred the addition of zetta and yotta.

The new prefixes can simplify how we talk about some pretty big objects. “If we think about mass, instead of distance, the Earth weighs approximately six ronnagrams,” which is a six followed by 27 zeroes, [sad Richard Brown, the head of metrology at the UK’s National Physical Laboratory]. “Jupiter, that’s about two quettagrams,” he added — a two followed by 30 zeros. Brown said he had the idea for the update when he saw media reports using unsanctioned prefixes for data storage such as brontobytes and hellabytes. Google in particular has been using hella for bytes since 2010. “Those were terms that were unofficially in circulation, so it was clear that the SI had to do something,” he said.

Earlier this month, agents from both the FBI and the U.S. Air Force raided multiple homes belonging to a man who runs a little-known blog about Area 51. Gizmodo reports: That man, Joerg Arnu, said the swarm of federal agents in riot gear busted into his primary residence, handcuffed him, then marched him outside to wait in the freezing cold while they rifled through his apartment and took pretty much every piece of electronic equipment that he owned. So far, the government has been pretty tight-lipped about the whole thing, but officials did verify that it happened. In a statement provided to the Las Vegas Review-Journal, Lt. Col. Bryon McGarry confirmed the raid. He did not elaborate on its purpose, saying only: “This is an open and ongoing law enforcement investigation between the Las Vegas FBI and Air Force OSI.”

What did cops want? It’s not exactly clear. Since 1999, Arnu has run Dreamland Resort, a website that covers activities in and around Area 51, the notoriously secretive government facility located in Groom Lake, Nevada. Long the subject of speculation and curiosity, the highly classified facility is the site of myriad UFO sightings. Coincidentally (or not), it is also the location where the Air Force reportedly tests and develops some of its most sensitive and experimental new projects and aircraft (see: the U-2 spy plane in the 1950s, for instance). Among other things, Arnu’s site features pictures and writing about the Air Force’s so-called “black projects” — opaque, classified operations carried out behind a veil of government secrecy. Arnu claims that the agents confiscated his “laptops, phones, backup drives, camera gear, and my drone were seized.” He describes the situation in detail in a blog post on his website.

“China has submitted the most research papers accepted at a prestigious international academic conference focused on semiconductors, underscoring the country’s growing presence in the field and bumping the U.S. into second place (Warning: source paywalled; alternative source),” reports Nikkei Asia. The committee of the International Solid-State Circuits Conference (ISSCC) was held in South Korea on Nov. 16. From a report: According to the committee, a total of 629 research papers were submitted for next year’s ISSCC, including 198 that passed the screening. The 198 include 59 from China, 42 from the United States and 32 from South Korea. China rose from third to first and South Korea’s number decreased by nine compared to the previous one. “China increased its selected research paper count in every category and the Chinese government played an important role in this,” one of the participants said […].

The academic conference in the field of semiconductor integrated circuit design was first held in 1954. It is the largest and most renowned international conference in this field and next year’s conference will start on Feb. 19 in San Francisco. More than 3,000 researchers from over 30 countries will attend it to share the latest technologies in the field.

An anonymous reader quotes a report from CNET: Fortnite developer Epic Games said Google paid the equivalent of $360 million to Call of Duty developer Activision Blizzard as part of a broad agreement that included a promise the gaming giant would not create a rival app store. The move, Epic said, helped solidify Google’s hold on phones and tablets powered by its Android software. In the filing, newly unredacted Thursday, Epic said Google paid other developers in a similar way to Activision. Epic cited an agreement Google struck with Tencent, the Chinese company that owns League of Legends developer Riot Games, giving it about $30 million over one year. Like Activision, that money too was part of a larger agreement for Riot to maintain its Google-powered games and spend money promoting them as part of Android.

Google and Activision Blizzard both denied Epic’s allegations about competing app stores. Google said the agreements are designed to provide incentives for developers to create apps for Google Play. “Epic is mischaracterizing business conversations,” a Google spokesperson said in a statement. “It does not prevent developers from creating competing app stores, as Epic falsely alleges.” Activision, for its part, said Google never “asked us, pressured us, or made us agree not to compete with Google Play.” Activision is in the midst of being acquired by software giant Microsoft for $68.7 billion. […] The filing is the latest allegation in Epic’s ongoing lawsuit against Google, which it accuses of operating a monopoly with Google Play, which sells apps for Android. Epic’s ongoing lawsuit is similar to another battle it’s waging against Apple and its App Store over similar concerns of monopolistic practices. In both cases, Epic is pushing the companies to reduce the control they exert over their respective platforms, both in terms of how phone and tablet owners pay for apps and where to download them from.

It’s unclear whether Epic’s argument that Google paid developers to not compete will win in an eventual court case. Epic said in its complaint that “Google understood” the agreement would mean that Activision would “abandon its plans to launch a competing app store, and Google intended this result.” But Armin Zerza, now Activision Blizzard’s finance chief, said in one of the court filings that the company chose not to launch a rival app store because of the risk of failure, in addition to costs for development and marketing. When asked about entering a deal with Google that “accomplished your objectives,” Zerza said that the Activision Blizzard board approved a deal with the Android maker because it “created multi-hundred-million dollars of value for us across multiple ecosystems.” If Activision is ultimately purchased by Microsoft though, it may end up helping create an app store after all. Microsoft told regulators in October that it intends to build its own mobile app store to rival Google and Apple. Activision’s deep library of popular games, including Candy Crush Saga and World of Warcraft, will be a key part of that effort. “Epic’s allegations are nonsense,” an Activision representative said in a statement sent to PC Gamer. “We can confirm that Google never asked us, pressured us, or made us agree not to compete with Google Play — and we’ve already submitted documents and testimony that prove this.”

Six years after we saw the FCC formally propose “nutrition labels” for your carrier’s potentially confusing array of plans, the agency says it’s finally happening. The Verge reports: This week, it’s ordering US internet service providers to adopt the label format you’re looking at [here] — or it will, as soon as some last bureaucratic elements get worked out. They’ve changed a bit since 2016 — now, each plan will apparently have its own label rather than ISPs trying to cram all of them into a single sheet, they don’t warn you about coverage, and apparently, ISPs will be able to point you to their network management policy legalese instead of having to ding themselves for throttling data or giving some apps a fast lane. They won’t have to report packet loss, either, it seems. Thankfully, ISPs will still need to report their typical speeds and latency, not just reiterate their advertised speed. Hopefully, someone will audit that.

Most big ISPs will have six months to slap the new labels onto their websites and distribute them in stores, though the FCC’s giving ones with less than 100,000 subscribers a full year to comply. But none of those shot clocks start until the Office of Management and Budget reviews the order to make sure it complies with the Paperwork Reduction Act and similar statutes, the FCC notes, so it might be a bit longer. In the meanwhile, FCC Chair Jessica Rosenworcel suggests that ISPs might want to get ahead of things and adopt them on their own. The FCC also says it hopes these labels will evolve from here […].
