This is devastating, and part of a larger move to entirely push science out of NASA's mission. It is horrific betrayal of so much work, not to mention the fact that it violates NASA's charter.

2019: "NASA is one of the most recognised, revered and iconic brands in the world" (davidsonbranding.com.au/nasa-modern-...). 2025: >1000 NASA mission-support staff (and 2800 other NASA employees) have left under the current administration.

It’s depressing how much faster it is to break a thing than it is to build it

@caltechipac.bsky.social is featuring me in their "Meet the Scientists" profiles! Check it out to learn more about how I became an astronomer, what I work on, and how I ended up at IPAC! www.ipac.caltech.edu/meet-the-sta... #exoplanets 🔭🧪

Thank you Mitchell Anderson for your Letter to the Editor in today's Daily Star.

Call it millennial cynicism if you like, but I truly believe nothing will turn the Republican base or leadership against Trump. Our only hope is getting young voters to turn out for elections, and every march/petition is useful only if it serves that goal.

DEMAND CISCOMANI MUST DO THE RIGHT THING. Tomorrow - July 2

Great result led by Kate Su at the University of Arizona: discovery of gas released by a giant impact around a 150 Myr-old star – glad to have contributed! #JWST #DebrisDisks #Exoplanets @jwstfeed.bsky.social @uarizonalpl.bsky.social @nasaexoplanets.extwitter.link

Meet your new cosmic neighbors ☄️ Introducing a swarm of over 2100 new asteroids discovered by NSF–DOE Rubin Observatory! Rubin discovered these asteroids in about 10.5 hours of observing across 7 nights. They've never been seen by humanity before...until now.🔭🧪 youtu.be/DTuq-vBsDJE

Because it's not being said as part of this press conference, @vrubinobs.bsky.social would not be possible without the many, many international scientists and collaborators, some around the world, but many who immigrated to the US and are scientists and engineers here

Here it is: www.youtube.com/watch?v=MIJf...

Zeljko talking about galaxies in @vrubinobs.bsky.social data, and showing off some amazing nail polish. A reporter asked what’s up with the color: it’s the signature observatory color scheme… branding!

Thrilled to wake up this morning to the first images from the Vera C. Rubin Observatory! Stunning images and videos - here’s the link: www.nsf.gov/news/first-i...

Twelve ALMA/AGE-PRO papers just out! Exploring how gas and dust evolve in disks 🌟🌀 — Congrats to all authors! 🎉 NRAO press release: public.nrao.edu/news/alma-pl...

I attended a meeting: "Recovery plan for Ukrainian astronomy" organized by @unileiden.bsky.social @astro4dev.bsky.social It was great to interact with Ukrainian astronomers, learn about their science and challenges. I look forward to fostering new collaborations in both the Netherlands and Poland.

Sen. Alex Padilla, who was just forcibly removed from a DHS press conference, is the ranking member of Judiciary’s subcommittee on immigration, citizenship, and border safety, which has “oversight of federal agencies with citizenship, asylum, refugee, and immigration enforcement responsibilities.”

It’s been a privilege to serve as Chair of the Executive Committee for NASA’s Exoplanet Exploration Program Analysis Group. I’m pleased to pass the torch to Prof. Ian Crossfield and look forward to his vision and leadership. #NASA #Exoplanets

Big congrats to Dr. Galen Bergsten on earning the title! If you’re wondering how many Earth-like planets are out there, Dr. Bergsten is the one to ask. #proudadvisor #Exoplanets #Astrophysics

The end of US leadership in science, technology, and innovation. All in one little table. A tremendous gift to China, courtesy of the GOP. nsf-gov-resources.nsf.gov/files/00-NSF...

AAS and 52 other science societies and organizations sent a letter to Congress this morning expressing concern over recent organizational and financial developments at NSF, and urging Congress to exercise its oversight authority to preserve American STEM leadership. aas.org/press/letter... 🔭

This is seismic. Isaacman had clearly articulated a strong support for science, and the withdrawal of his nomination yet further imperils NASA's Science Mission Directorate. www.semafor.com/article/05/3...

Loved sharing a visit to the Mirror Lab with my parents - watched the rotating furnace in action and saw two of the Giant Magellan Mirrors. Big thanks to Laura Mark for the excellent tour! A must-see if you are in Tucson. #Astronomy #GiantMagellanTelescope #UniversityOfArizona #STEMOutreach

Great quote here by @katestarbird.bsky.social, that we can’t shy away from voicing the harm and lies being done to science and scientists.

Happy Easter to all who are celebrating today. This season of renewal invites us all to believe in the triumph of light over darkness, life over death, love over hate.

Harvard has set an example for other higher-ed institutions - rejecting an unlawful and ham-handed attempt to stifle academic freedom, while taking steps to make sure students can benefit from an environment of intellectual inquiry, rigorous debate and mutual respect. Let’s hope others follow suit.

I see it. I have lived it. 83 years ago, the U.S. government turned upon a group of its own citizens and residents and sent them to internment camps without due process. I was there among them. American fascism is back. It is here. It is now.

They are further consolidating control over the priorities of federal science funding.

From Skylar Grayson/Cole Meldorf/Abby Lee/Drew Lapeer/Catherine Slaughter: NASA is facing severe budget cuts that would cancel missions ready for launch, put tens of thousands out of jobs, and set science back decades. We need your help to ask Congress to prevent this! astrobites.org/2025/04/15/h...

I'll be on CNN at 9pm ET with Kaitlan Collins to discuss today's news of the astonishing security failure at the White House.
