In the latest from Nature: with half a million satellites set to launch in the next decade, more than 96% of images from some space telescopes could be obscured. “We will have fewer discoveries, less interesting images, and in general, less knowledge.” 🔭🧪 www.nature.com/articles/d41...

New: Researchers are broadly rejecting the Trump administration's compact. In faculty votes and student protests, they have mobilized to pressure their universities—to some effect: 6 of the original 9 universities have rejected the compact With @alexwitze.bsky.social and @jennaahart.bsky.social:

Is this the elusive ultra-long GRB ???

babe wake up, an entirely new type of object just dropped

ICYMI: Astronomers are finally solving the mystery of JWST’s little red dots, and they seem to be a hybrid sort of black hole star!! 🔭🧪 “It’s almost a shame that we’re starting to figure them out,” Anna de Graaff told me. www.nature.com/articles/d41...

A consensus is emerging that these mysterious little red dots, sometimes called rubies, are an entirely new type of object in the Universe. go.nature.com/4hjIGm4

First exoplanet story since August—reclaiming my brand

Not common to see a 7-byline story in the wild, but that's what the situation calls for when the government shuts down and every science agency needs to be checked in on for RIFs, grant terminations, and general dysfunction. Our update on what the chaos means for science here:

Less than 70% of science Nobel prize winners awarded this century hail from the country in which they were awarded their prize. “Mobility benefits everyone. Each newcomer brings fresh ideas, new techniques & different ways of looking at old problems” 🧪 #academicSky www.nature.com/articles/d41...

Who said the science part of Nobel week is over!? In my new analysis for Nature, over 30% of science laureates from this century have immigrated, and two thirds came to the US. www.nature.com/articles/d41...

Of the 202 Nobelists who have been awarded prizes in physics, chemistry and medicine this century, less than 70% hail from the country in which they were awarded their prize, a Nature analysis shows. go.nature.com/48UbZJp

You've probably heard how a high percentage of #Nobel laureates are immigrants. The US in particular has benefited from the influx of bright minds. @jennaahart.bsky.social ran the data for this century's Nobel prizewinners — and shows more than 30% immigrated. 🧪 www.nature.com/articles/d41...

Big day for physics teachers who tell their students “If you slap the desk, there’s a 1 in 5.2^61 chance that your hand will pass right through”

"This detection will quickly 'become one of my favourites', says David Reitze, executive director of the LIGO laboratory" @jennaahart.bsky.social reviews some of our greatest discoveries, including the new #GW250114 in Nature News www.nature.com/articles/d41... #GW10Years 🧪⚛️🔭

Happy birthday to GW150914, our first (of many) #GravitationalWave discoveries, detected 10 years ago today! #GW10Years 🧪⚛️🔭 🖼️: @chirpmass.bsky.social

Ten years ago, the #LIGO gravitational-wave detectors in Louisiana and Washington first heard the ripples in spacetime created by some of the most violent cosmic collisions. For @nature.com, @jennaahart.bsky.social looks back at LIGO's greatest hits: www.nature.com/articles/d41... #physics 🧪

New from Nature: Latest LIGO results from GW250114 confirm Hawking’s black hole area theorem with 99.999% confidence!! “It was the perfect 10-year anniversary present.” More on this detection and LIGO’s other greatest hits from its first decade of discovery 🧪🔭 www.nature.com/articles/d41...

Amazing early birthday present for GW detections !!

WELCOME TO THE FAMILY, ALPHA CEN A b!!! First hinted at in Wagner+21, now Chas Beichman, Aniket Sanghi and team have published new JWST images of alpha Cen A showing another hint of this Saturn-sized planet candidate! exoplanetarchive.ipac.caltech.edu/overview/alp...

New from Nature: “I had to take a moment of silence to appreciate what I was seeing.” Astronomers reveal what could be the first ever image of a planet in its star’s habitable zone—and in the same star system as Avatar, no less www.nature.com/articles/d41...

“It’s a ransom to release funds.” During my conversations with Columbia scientists about the university’s new settlement, the word “foreboding” came up in just about every interview. Hear their thoughts in my @nature.com story with @alexwitze.bsky.social: www.nature.com/articles/d41...

Columbia scientists say they are relieved, yet unsettled, after last week’s deal with the US government to restore university research funding — and they’re figuring out how to get back to work. go.nature.com/3Ja40wY

I think the only thing more breathtaking than Rubin’s first images was hearing their lengthy backstory from Tony Tyson. If you’re interested in how it took 30 years to create these snapshots, my story below:

Tony Tyson is one of the key figures behind an ultra-vivid new era of astronomy. In a conversation with ‪@jennaahart.bsky.social‬, Tyson discusses dark matter, dark energy and the decades-long effort to build the Rubin Observatory (‪@vrubinobs.bsky.social): www.quantamagazine.org/the-biggest-...
