Space is full of unsolved mysteries, and a team using NASAs James Webb Space Telescope have recently turned up a doozy. "I remember after we got the data down, our collective reaction was 'What the heck is this?' It's extremely different from what we expected," said Peter Gao of the Carnegie Earth and Planets Laboratory in Washington, a co-author on the study. The researchers found an exoplanet dubbed PSR J2322-2650b that orbits a small, dense star emitting electromagnetic radiation known as a pulsar. They are an example of a black widow system, where a rapidly spinning pulsar is paired with a smaller astronomical body. A black widow duo isnt unusual, but this pair has sparked questions about how the exoplanet originally formed. The exoplanet's proximity to the pulsar and its intense gravitational pull have distorted it into an oblong lemon shape. More unusually, PSR J2322-2650b also has a unique atmosphere comprised mostly of helium and carbon. "Instead of finding the normal molecules we expect to see on an exoplanet like water, methane, and carbon dioxide we saw molecular carbon," principal investigator Michael Zhang of University of Chicago said. Given its strange atmosphere, the team isn't certain how the exoplanet formed. "It's very hard to imagine how you get this extremely carbon-enriched composition. It seems to rule out every known formation mechanism," Zhang said. For now, well chalk this up as another mystery of the universe.This article originally appeared on Engadget at https://www.engadget.com/science/space/astronomers-find-mysterious-lemon-shaped-exoplanet-with-nasas-webb-telescope-223722244.html?src=rss

NASA has a leader again. On Wednesday, the US Senate confirmed Jared Isaacman as the agency's administrator, with a 67-30 vote. The billionaire entrepreneur (and Elon Musk ally) will have his hands full navigating political waters while managing a severely downsized workforce.You might recall that this wasn't Isaacman's first shot at the job. He was nominated to the post earlier this year. But days before he was scheduled for a confirmation vote, President Donald Trump withdrew his nomination.The reversal reportedly came after the president was told that Isaacman had donated to prominent Democrats. (Trumps description of his decision, as based on a "thorough review of prior associations," seemed to lend weight to that.) However, that was also around the time the Trump-Musk feud was about to boil over. Regardless, Isaacman was nominated again in November.The new NASA head reportedly has broad support from the space community. (That makes him something of an aberration among Trump appointees in scientific fields.) "I am optimistic that Mr. Isaacman will bring a steady hand and clear vision to NASA," Sen. Marie Cantwell (D-WA) told The New York Times.The new administrator has traveled to space twice on private missions. In a document published in May, Isaacman shared his three objectives for NASA. These included human missions to the Moon, Mars and deep space; helping the organization do more with a constrained budget; and cost-cutting through industry and academic partnerships.This article originally appeared on Engadget at https://www.engadget.com/science/space/jared-isaacman-is-nasas-new-leader-220833691.html?src=rss

YouTube announced that it will no longer share data with Billboard for the creation of the Billboard Hot 100 and other charts because the video platform doesn't believe they're calculated fairly. The issue lies, per YouTube, with how Billboard weighs on-demand streams in its rankings: The publication weighs streams from paid music streaming services over ad-supported streams, and YouTube just so happens to run an ad-supported streaming service.Much like getting a book on The New York Times Bestseller list, landing a spot on the Billboard charts doesn't carry quite the same importance that it once did. When the majority of the media people consume is digital and on-demand, sales numbers aren't a guaranteed indicator of success or popularity. That's part of the reason why Billboard started including digital streams in its calculations way back in 2007, and why it announced plans to adjust how it weighs on-demand streaming just yesterday.On Tuesday, Billboard announced that it would add more weight to streaming to "better reflect an increase in streaming revenue and changing consumer behaviors." Billboard currently counts an "album consumption unit" as an album sale, which either breaks down to "3,750 ad-supported or 1,250 paid/subscription on-demand official audio and video streams." In the new ranking scheme that will go into effect in January 2026, "each album consumption unit will now equal 2,500 ad-supported or 1,000 paid/subscription on-demand official audio and video streams." "The change means that it will take 33.3 percent fewer ad-supported on-demand streams of songs from an album, and 20 percent fewer paid/subscription on-demand streams of songs from an album, to equal an album unit," Billboard says. Put another way, things are moving in YouTubes favor, just apparently not as quickly as the company wants.YouTube characterizes pulling its data from Billboard as fighting for fairness and equality, but it's equally connected to the platforms demonstration of its own power. It already funnels billions of dollars to artists and labels from the money it makes on ads and subscriptions, but it clearly also wants the power to mint new chart-topping stars. We are committed to achieving equitable representation across the charts and hopefully can work with Billboard to return to theirs, YouTube says in its announcement. Until then, if you're curious about what music is making waves on YouTube, you can visit our charts here.This article originally appeared on Engadget at https://www.engadget.com/entertainment/music/billboards-charts-are-increasingly-weighted-towards-on-demand-streaming-but-not-enough-for-youtube-220238291.html?src=rss
