Maryland voters: join me on the @aas.org Zoom on Friday at noon. I'll give a short summary of the congressional appropriations process, and I'll walk you through making your own request for funding for NASA, NSF, and DOE Office of Science. 🧪🔭 Zoom at noon on Friday, April 18: bit.ly/3Y1cJq2

Couldn't think of a beta title. 👏

If you see me today and wonder what’s wrong with my skin: I bathed in Old Bay shortly after watching this. 🦀

Maryland Sen. Chris Van Hollen is demanding a meeting with El Salvador President Nayib Bukele over the detention of Kilmar Abrego Garcia and says he’ll go to El Salvador himself if the Marylander isn’t returned.

Rep. Marjorie Taylor Greene disclosed that she had purchased between tens and hundreds of thousands of dollars worth of stock on April 8 and 9, the day before and the day of President Trump’s announcement that he was pausing a sweeping set of global tariffs.

“If you cut the science programming in half, you hurt our country in many ways,” Van Hollen said. “You hurt our national security. You hurt our innovation economy. You hurt our leadership around the world.” 🧪🔭

From today’s run under tree-lined streets in Baltimore: may I exchange this bird *shit* in the hand for the equivalent value in a bush? I’d prefer that option, thanks.

The American Astronomical Society is gravely concerned by the deep cuts to NASA science funding reported to be in the draft President’s Budget Request for Fiscal Year 2026. Read more here: aas.org/press/aas-st... and take action now: aas.org/urge-nasa-su...

"What does NASA do for us?" Here's Ohio. 🔭🧪

"What does NASA do for us?" You might think NASA only benefits Americans in Florida or Texas. You'd be wrong. 🔭🧪 www.nasa.gov/fy-2023-econ...

I can’t think of a nation on earth who would try to beat the US in a space race. Oh wait. 🧪🔭

NASA could have been a good argument for American exceptionalism. NASA is a driver of American competitiveness in technology development and engineering. So let’s disembowel NASA? 🔭🧪

Today at 1 pm the @aas.org will host a webinar on how to advocate for science with your representatives in Congress. What a day for it. I just spoke with my representatives. Want to know what I said, and how to do it? I’ll be a panelist at the webinar, come by and I’ll tell you. 🔭

The president's budget request seeks to strangle astronomy in the US. The president's hit job specifically seeks to murder the Nancy Grace Roman Space Telescope – a revolutionary facility that is fully assembled, on budget, and nearly ready to launch. 🧪🔭 arstechnica.com/space/2025/0...

Congratulations to Pa Chia Thao for successfully defending her PhD thesis today on the discovery and atmospheres of young planetary systems. #exoplanets #exoplqnet #jwst ⭐️🔭🧪🌌 To my knowledge, Dr. Thao is the first Hmong to receive a PhD in astronomy in the US.

After maybe wikipedia, the most important page on the internet is hiring. 🧪🔭

As Lincoln said: “a house divide can burn itself out, the fire department was defunded by arsonists.”

The hour is getting late. America, do you know where your scientists are? 🧪

The NSF's flagship fellowship program typically gives offers to 2,000+ young scientists. This year, in the face of looming budget cuts, that number was halved: only 1,000 received an offer. Our story on what that means for the science talent pipeline: www.nature.com/articles/d41...

Man after my own heart

Today in everything is a metaphor, geoscientists have discovered that the craton, the enormous stable rock that forms the core of North America, is eroding away www.jsg.utexas.edu/news/2025/04...

haha no I’m not blushing, I just appear red due to gravitational redshift as I’m crushed into a dense singularity in these trying times hahahaha 🔭

🆕 This new #Hubble Space Telescope image of NGC 346 kicks off celebrations for the upcoming #Hubble35 anniversary – the first in a series revisiting previous Hubble targets, combining new processing techniques with the latest data 🧪🔭 esahubble.org/news/heic2502/ #50YearsOfESA @science.esa.int

Astronomy grad students!! 🔭🪐 Applications are now open for the 2026 IPAC Visiting Graduate Student Fellowships. Come work in sunny Pasadena for six months (tuition and stipend covered!) and work on an exciting project with an IPAC scientist (including me!). www.ipac.caltech.edu/page/graduat...

Today I visited my senators and some of my colleagues’ reps to advocate for basic science with the @aas.org Congressional Visit Day. I spent my whole voice today. (aside: Booker, how’d you do that last night?) What are you going to do tomorrow? 🧪🔭

It’s a good week for brown dwarf science and #blackinastro #blackandstem! Congrats to @bemiles.bsky.social on the new faculty job!!!! Congrats to @capricephillips.bsky.social on the Hubble Fellowship!!!!

PEP 751 has been accepted! peps.python.org/pep-0751/ This means #Python now has a lock file standard that can act as an export target for tools that can create some sort of lock file. And for some tools the format can act as their primary lock file format as well instead of some proprietary format.

I am thrilled to announce my second PhD paper, under the supervision of Luan Ghezzi, Kevin Heng, and Chloe Fisher 🪐📄 This study is a summary of my PhD thesis (2019–2024), where we analysed retrievals of HST WFC3 transmission spectra and parameter degeneracies associated with them. Read more ⬇️

ESA's Gaia mission has been a milestone in our understanding of the Universe. Its farewell closes a chapter, but it leaves behind a remarkable legacy of discoveries that will continue to influence astronomy for decades to come. Thank you, Gaia. 🔭 🧪 #Gaia #ESA #histsci #stellarastro #cosmology

We polled Nature readers to ask if they were thinking of leaving the US for jobs abroad. Three-quarters of them (who said they were US-based scientists) said yes. 🧪 www.nature.com/articles/d41...

In the heat of battle that was submitting my PhD thesis, I completely forgot to share this with you! @nature.com invited us to contribute a Research Briefing on our latest #exoplanets paper 🪐 Hope you enjoy it 😊

This would be a neat idea if these research institutions had any intentions of hiring and keeping early career scientists from varied backgrounds and origins. I’m genuinely worried folks will move for short contract offers and wind up back in the US, and in debt, before the administration ends. 🧪

SCOOP: The Trump administration is planning to eliminate an entire team at the National Institute of Standards and Technology responsible for publishing critical data that underpins advanced scientific research around the world. from me and @willknight.bsky.social www.wired.com/story/nist-d...

From a spokesperson just now: “NASA is committed to optimizing its workforce and resources in alignment with [DOGE] initiatives. As part of this effort NASA has identified and phased out $420 million in contracts that were determined to be redundant or misaligned with our core mission priorities."

NEW: #NASAWebb reveals a distant spiral galaxy perfectly aligned near the tip of Herbig-Haro 49/50—an outflow generated by a nearby still-forming star. This near- and mid-infrared image uncovers intricate details about how stars form: webbtelescope.pub/4iGQg9K 🔭 🧪
