Graphic with the text "Action Alert: AAS urges advocacy against proposed cuts to science in President's Budget Request"

The President's Budget Request proposes a 47% cut to NASA Science, a 55% cut to NSF, and a 13% cut to the DOE Office of Science. AAS President Dr. Dara Norman sent a call to action to AAS members via email today. Urge your members of Congress to reject these cuts now! aas.org/reject-2027-...

One season's view of the Roman Space Telescope's
Galactic Bulge Time-Domain Survey.

Roman will study millions of stars, and how they vary in time. It will reveal tens of thousands of planets throughout the Milky Way, including habitable rocky planets.

Plus many unknown unknowns! 🔭🧪🤞 #stellarastro

Posted this and a friend texted to say they were on the fence about going and this tipped them into going. Let your friends know you're going! Invite them along! They're mad too and doing something always feels better than doing nothing. We're in this together. ❤️👊

I don't think people fully appreciate how apocalyptic things are for US science. I haven't had any new funding since 2024, but I'm still ok since typical grants are for three years. This means next year I will be completely out of funding and will have to fire everyone in the lab. It's not great.

Fig 7: Spot filling factors of HAT-P-11 as a function of time. Filling factors derived from rotational variability in Kepler
and TESS light curves (using Equation 2 of Rackham et al. 2019) are compared with values inferred from multi-component
spectral fits to HST G102 and G141 data. Independent chromospheric activity measurements (S-index values from the literature)
are shown on the right axis. The Kepler era exhibits relatively high filling factors with substantial variability, whereas the TESS
epochs indicate a transition to markedly lower spot coverage. Red vertical dotted lines mark the epochs of JWST observations

Sweet deep dive from Prajwal Niraula, @benrackham.bsky.social et al. on a star near and dear to my heart. #stellarastro 🔭

Evidence from HST, Kepler, TESS, and ground-based spectroscopy all agree: 2024 #JWST observations HAT-P-11 were taken near activity minimum.

FWIW absolutely no one I know who has expertise in spaceflight or planetary exploration thinks this is either remotely plausible or a good idea to attempt on such a timeline. The dominant reaction is somewhere on the spectrum between mockery and dismay. Real, important science was cancelled for this

Rocky Worlds DDT Data Challenge and Data Challenge Workshop — Save the Date

For hunters of rocky worlds: save the date! 🔭 #astrocode

We're preparing a Data Challenge modeled after the 2015 Spitzer Exoplanet Data Challenge, this time with MIRI observations from the Rocky Worlds DDT program.

Have you noticed the brimming graveyard of proposals I’ve left in my wake?

Some people say it gets easier to accept the low odds, but I’ve never felt that way. 🔭

Good to remember. Everyone who writes proposals gets 5th quintile rankings. sometimes there are lessons to learn for sure, but there’s a huge randomness factor.

My bet: top, private institutions with endowments are going to pay for the most advanced AI tools, generating more academic noise and superficial hype, while public universities doing the real work get defunded year over year.
