First the rumour was a 20% budget cut. Then, 50%. Now the president's NASA budget is out and it's a 68% cut to astrophysics ($1.5B to $487M).
Even if this gets reversed in four years, we will *never* recover the missions, partners, people who will be gone.

Massive cuts to NASA science proposed in early White House budget plan
The preliminary version of President Donald Trump’s budget proposal to Congress, known as a “passback,” would cut the agency’s science budget funding nearly in half.

Lights, camera, action!
The world's largest digital camera has been installed at NSF–DOE Rubin Observatory! 🤩
The LSST Camera was the final major component of the observatory. With it in place, Rubin officially enters its final phase of testing!🔭

Stop saying "the government that governs best governs least."
That's never been true.
The government that governs best governs the right amount.
A government that abdicates its duties to the public is no government
of the people,
by the people,
or for the people
at all.

My graduate student Dillon Hasenour just got this paper accepted to ApJ! 🧪🔭
He developed methods for incorporating a nuclear network onto a moving mesh and developed benchmark tests to demonstrate the advantages, including a semi-analytic solution for a detonation wave!

Quantifying Advantages of a Moving Mesh in Nuclear Hydrodynamics
Many astrophysical explosions, such as type Ia supernovae, classical novae, and X-ray bursts, are dominated by thermonuclear runaway. To model these processes accurately, one must evolve nuclear react...

Good Morning! The latest episode of the Astrophysics Podcast is out today! I'm interviewing Dr. Lindsey Kwok, a research fellow at Northwestern University. She uses JWST to learn how supernovae exploded!

Received this e-mail from the NSF this morning.
The webpage it directs you to for submitting questions doesn’t give you any way to receive a response; when you submit a question it says “Your response has been submitted” and claims that they’ll put together a FAQ page.

Through an almost unbelievable series of events, I got a selfie with the Chief Scientist of JPL, Dr. Jonathan Lunine, in front of the Nancy Grace Roman Space Telescope last week!

Episode 12 of The Astrophysics Podcast just dropped! I interviewed Dr. Brenna Mockler from Carnegie Observatories. She is a theorist who works on what we call "Tidal Disruption Events" -- essentially, what happens when a black hole eats up a star! Check it out! 🧪🔭
