Oh hey I write for Scientific American, too!
Today's weekly "The Universe" column is about how we can actually *resolve the disks of some stars*, and how we do it.

To See a Star’s Face, You Have to Interfere with It
A technique called interferometry can greatly magnify tiny objects on the sky, and is powerful enough to reveal the surfaces of nearby stars

New regulations are needed to protect #RadioAstronomy from satellite mega-constellations.
We deliberately build our telescopes in the outback to avoid radio frequency interference (e.g. from TVs, microwaves, phones) but now unintentional transmissions from satellites are affecting images.

We've known for a while that satellite mega-constellations like SpaceX's Starlink are a problem for optical astronomy. Now, a new survey shows they're also adversely affecting radio astronomy – including at wavelengths supposedly protected by international regs. 🔭⚛️🧪 physicsworld.com/a/starlink-s...
Starlink satellite emissions interfere with radio astronomy – Physics World
Largest-ever survey shows new regulations on unintended transmissions are needed, say researchers at Australia’s Curtin University

The WH proposes $6 billion cut in NASA budget, an overall 24% reduction from previous year – and a shocking 47% cut in funding for NASA’s Science Mission Directorate [reductions to to NASA’s fleet of spacecraft already in space, or proposed], an extinction-level event for the Earth & space sciences.

For folks who don’t know, ethnic studies programs like African American/Africana Studies, Asian American Studies, Chicano Studies and the like come directly from civil right era campus activism. Attempts to disempower such programs should be framed as attacks on civil rights same as much else rn.

NSF appears to be terminating hundreds of its grants to Harvard, per internal sources at NSF and at Harvard. At least one division has had all its grants cut.
