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...

Clearest gravitational-wave detection yet confirms Hawking’s black-hole theory
Discovery joins a list of the greatest hits of the LIGO detector, which ten years ago became the first to detect gravitational waves.

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 🧪🔭

128 new mergers between black holes and neutron stars.

Today we're revealing the biggest ever update to our count of gravitational wave detections. New data from May 2023 to January 2024 has more than doubled the number we've seen.

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!

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

Alien planet glimpsed in star's 'habitable zone'
A smudge of light spotted by the James Webb telescope near Alpha Centauri A could be the planet with the tightest orbit ever to be imaged directly.

“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:

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.

Happy Friday! A mysterious chemical signature seen in the remains of Neanderthals might be explained if they snacked on a special culinary garnish: maggots. 🤢
