And on humanity's visionary side: Not only can we see neutrinos, we can now measure their spectrum. In essence, we can see neutrinos in *color* and start to track down the cosmic sources that create them. 🔭🧪 www.science.org/content/arti...

You've probably heard about how the rapidly increasing numbers of satellites are affecting #astronomy. A new paper in @nature.com looks at the possible future for space-based telescopes — and finds 96% of some images could be impacted. 🧪🔭🛰️ By @jennaahart.bsky.social www.nature.com/articles/d41...

I really hate it when scientists keep saying that “we need to rebuild trust in science,” because it implies that scientists are to blame for the mistrust rather than the millions of dollars of dark money that have funded political attacks on science in order to advance a far right agenda.

Today is #LGBTQinSTEMDay 🌈 ESA proudly joins the STEM community in celebrating the unique contributions of LGBTQ+ individuals. The Pride Flag will fly across ESA sites as a reminder of how far we’ve come, and how much more there is to do. #SpaceForAll

Hi, it's me again. I'm reposting this today because a whole lot of people who saw this yesterday told me they appreciated it. Know this: I believe in you. If you need permission to have some quiet space for yourself, here it is. <3

Help the @vrubinobs.bsky.social team tune their alert system by identifying which image changes are real astrophysical events and which are cosmic imposters using early data collected by the observatory. Join Rubin Difference Detectives project on Zooniverse: www.zooniverse.org/projects/ebe...

I mean, who wants to stay in a country actively stripping away your rights and personhood?

🧪 "@siricarpenter.bsky.social and I started TON because we wanted to understand how our colleagues produced their work...We wanted to go behind the scenes and learn everything about the process ... TON was then, as it remains today, a labor of love." -- @jeanne-erdmann.bsky.social

With all the strong geomagnetic activity ongoing tonight, have you ever wondered how strong these events need to be to cause some damage? Has this happened in the past? I’d be silly not to use tonight’s hype to promote my new book, ‘Space Hazards’, which explores these questions!

If you have a very low-latitude aurora observation from tonight, please record your exact time and rough location and DO NOT DELETE your photo. These observations will be important for scientific research of this event. Comment below if you have a low-latitude aurora sighting.

For anyone applying to grad school in the US this fall, the @aas.org has made a working group to monitor which programs have faced cuts - this spreadsheet contains all the info: 🔭☄️

It may look like CGI, but this is the real deal: It's an accurate 3D rendering of our galactic neighborhood, highlighting the locations where new stars are being born. This animation is based on measurements of 44 million stars by the Gaia space telescope. 🧪🔭 www.esa.int/Science_Expl...

In my latest piece for The Planetary Report, I argue that we’ve largely lost the rhetorical ability to defend the unquantifiable values of space exploration—beauty, curiosity, discovery—in the face of an unrelenting focus on utilitarian pragmatism. www.planetary.org/articles/a-c...

Everything in this is true. It’s so real and hits so close to home and I hate it. www.wired.com/story/the-de...

Trump’s NIH cuts are hitting cancer research hard. NCI scientists say grant funding has been slashed, lifesaving trials canceled, and top researchers pushed out. It's a crisis in the making, and lives are on the line. NIH employees spoke out. Support them here ➡️zurl.co/2AW7t zurl.co/6FaQW

4,000 NASA workers are leaving through deferred resignation. "The cuts amount to an estimated 20% of NASA's workforce" www.npr.org/2025/07/26/n...

NASA employees have released their own 'dissent' letter, joining NIH and EPA employees in protesting agency changes in the Trump administration. They call it the Voyager Declaration. Words by me: 🧪🛰️ www.nature.com/articles/d41...

“The signatories of the #VoyagerDeclaration warned the space agency’s leadership about the consequences of major budget cuts that would halt many science missions.” Sign your support for the #NASA employees: actionnetwork.org/forms/suppor... www.nytimes.com/2025/07/21/s... @kchang.bsky.social

Makenzie Lystrup's departure from the Goddard Space Flight Center coincided with the release of an open letter to NASA's interim administrator signed by hundreds of current and former agency employees.

🪐 Use these #ViewSpace Interactives to spy newly forming stars hidden inside giant clouds of gas and dust, search for pulsars in the remains of exploded stars, witness the effects of galaxy collisions, and more. 🔭 🧪

Read this. And then call your Senator and tell them to save NASA science. www.planetary.org/articles/sci...

What’s really at stake if NASA’s science budget gets slashed and entire science missions are canceled? We asked the scientists leading those missions, and their stories reveal what we all stand to lose. Here’s what they told us: www.planetary.org/articles/sci...

JULY 16, 7 p.m. ET: #NASARoman is NASA’s next large strategic mission. STScI's Dr. Kristen McQuinn will tell us how Roman is set to chart the depths of space and time and forge the path towards Earth 2.0: www.youtube.com/live/2NpN8ae... 🔭 🧪

I cannot articulate to you how damaging this will be to NASA science and to the scientific leadership of the United States generally. To say nothing of the precedence of the White House and NASA leadership simply ignoring Congress. arstechnica.com/space/2025/0...

You’ve seen our advocacy efforts to Save NASA Science—here’s what happened and what’s next as we approach critical budget decisions in Washington. ⬇️ www.planetary.org/articles/sav...

Just thinking of the Harvard computer women a century ago, who looked at images of the universe like this by eye to make discoveries. They revolutionized astronomy, and Rubin definitely will too! Also, wow how excited would Henrietta Leavitt and Williamina Flemming be to see this! 🤩 🔭🧪🎢

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

On this First Look day for the Vera C. Rubin Observatory, I’m so proud to have written the initial drafts of the NOIRLab press release on how Rubin and LSST will revolutionize our studies of variable stars! ⭐️ rubinobservatory.org/news/rubin-u...

So exciting!! Can’t wait to see those first images!

The just-completed Vera C. Rubin Observatory is set to transform astronomy. Its wide and fast survey will discover billions of dynamic objects while building up a deep map of the universe. Learn more in this week's issue of Science: scim.ag/4n6oiak

We will never get out of our current hellscape until we fully embrace the idea that abusing power should be grounds for losing power.

Seven charts that show the perilous situation NASA is facing. www.planetary.org/articles/nas...

Last week, NASA and NSF released their FY26 budget requests. We list the detailed impacts on the astronomical sciences in this blog post, and share how you can take action today. aas.org/posts/news/2... @policy.aas.org

"You’re punching a generation-size hole, maybe a multigenerational hole, in the scientific and technical workforce. You don’t just Cryovac these people and pull them out when the money comes back. People are going to move on.” www.scientificamerican.com/article/prop...

From Skylar Grayson @skylargrayson.bsky.social : This post summarizes the proposed major cuts to NASA and the NSF and the impacts they would have, and provides resources to help fight back against this wasteful and unnecessary attack on science. 🔭✨☄️ astrobites.org/2025/06/02/b...

We're going to learn some tough stuff today about the White House's proposed budget for fiscal year 2026—including what they have in mind for NASA. I'll share what I hear, but remember: CONGRESS decides how much money NASA gets, not the White House. So whatever happens today, the fight continues.

Four charts showing the extent of cuts to NASA in the FY26 budget: - Cuts to every science division - Smallest science funding since 1984 - 19 active, inflight missions cancelled - Smallest NASA budget since FY 1961
