Not Their First Rodeo: Gravitational Wave Detectors Spot Merging Black Holes That Have Merged Before The gravitational wave events GW241011 and GW241110 provide strong evidence for the growth of black holes through successive mergers.

Star-Crossed Clusters: When Ages Are at Odds If you measure the age of a star using two different methods, do those ages agree? New research shows where our age estimates might be mismatched and what this disagreement could mean.

There’s more than one way to measure the age of a star in a cluster. But do different age-assigning methods agree? aasnova.org/2025/06/04/s... @ufresearch.bsky.social 🔭🧪

Senate Votes to Rescind Some Trump Tariffs, With G.O.P. Support A measure to cancel some Canadian tariffs is all but certain to stall in the House. But with a handful of Republicans in favor, the vote sent a signal of opposition to the levies.

Several Republicans joined Senate Democrats to pass a measure seeking to block some of President Trump’s tariffs on Canada.

Screenshot showing list of top 5 cited papers in the Astrophysical Journal Letters, with the first black hole image paper in position 4!

Thanks to @fredrasio.bsky.social, I was pleasantly surprised to learn that our first black hole image paper is in the top 5 most cited papers in the Astrophysical Journal Letters! I'm also sort of shocked that the top 5 cited papers are all about black holes or neutron stars, not exoplanets?! 🔭🧪

Legendary former NIH director retires from embattled agency Dr. Francis Collins is leaving the National Institutes of Health, where he served as director from 2009 to 2021. The agency is facing cutbacks and restrictions under the Trump administration.

White House budget proposal could shatter the National Science Foundation “This kind of cut would kill American science and boost China.”…

The US government has been turned over to a group of extraordinarily ignorant people, and they are working to destroy science in this country. Cutting over half the NSF budget would save < 0.1% of the federal budget, but do incalculable harm. Simply heartbreaking.
