🚨 HEADS UP: If you haven't submitted a comment on the OMB proposal yet, there's still time - but it's running out! There are only 11 days left to push back against Russell Vought's attempt to give political appointees unprecedented control over federal research funding. Take Action: zurl.co/R83IO

The moment we've all been waiting for is finally here… On June 29, 2026, NSF–DOE Rubin Observatory officially began the Legacy Survey of Space and Time (LSST)! 🔭🧪☄️🌌 🔗: rubinobservatory.org/news/action-...

Wait does this work

My grandfather was a baker. Late in life he went to college. These are from his astronomy class notes, 1962.

Macron: Do you think we should invite him to Versailles so he can sign the deal in the palace? Aid: Don't you think he or someone around him will understand the historical parallel? Macron: Aid: Macron: Aid: yeah, lets do it.

tl,dr; Scientists no longer allowed to use federal funding to publish, attend meetings, or talk to the public. They cannot collaborate internationally. Grants can be cancelled for any reason, at any time, political appointees have a final say over what gets funded, and who gets funded.

BREAKING: New proposed OMB regulation, applying to all federal grants, requiring grant reviews by senior political appointees and re-emphasizes that "peer review remains advisory and does not replace agency discretion". #standupforscience public-inspection.federalregister.gov/2026-10817.pdf

A nice paper by @asborlaff.bsky.social showing that launching telescopes to space doesn't necessarily solve the light pollution issue from satellites. These are satellite trails seen by NASA's SPHEREx space telescope, which appear in 73% of all its images. Eek. arxiv.org/abs/2605.27501

We've written about AI-induced physician deskilling that has already surfaced thelancet.com/journals/lan... @tberzin.bsky.social AI-induced never-skilling among newly trained doctors, while not yet proven, is a serious concern that needs to be addressed nature.com/articles/s41...

Fun news: Burcin's galaxy is published as today's (May 26th) NASA Astronomy Picture of the Day 🙂 apod.nasa.gov/apod/fap/ap2...

Q: Does my thesis adviser pick the snake? A: No. Your adviser just tells the guy who picks the snakes how good your thesis was.

"For too long, the university has ignored the wisdom of the donor class and hired based on academic excellence. Regrettably, this has led to the underrepresentation of discredited viewpoints in elite higher education." www.mcsweeneys.net/articles/wer...

Here we go! Gaia DR4 now has an official release date: 2 December 2026. If you have been following the Gaia Mission closely, you will know that DR4 has had a sliding release date, from the end of 2025, to mid 2026 to "end of 2026". But now the date is locked. www.cosmos.esa.int/web/gaia/dat...

An ominous slug looms over its prey

Happy perfect date day!!! With #alttext

The FY 2027 NASA budget request hides its science cuts by omitting mission names instead of explicitly zeroing them out. We did the work and found 54 missions cancelled in this proposal. This is another extinction-level event for NASA science. Full list: planetary.org/save-nasa-science

Mooooooon (ok mostly Earth so far)

🔭 Paper day, and it’s a big one! We have found the most metal-poor object known in the universe. It’s a star, and it comes to us from our nearby friend the Large Magellanic Cloud. Out in Nature Astronomy today: rdcu.be/fbylI

Hey, I wrote a thing about AI in astrophysics ergosphere.blog/posts/the-ma...

SADLY my April Fool’s paper on this topic has been desk rejected by arxiv moderators!!

It’s truly insane that an object with metallicity upper limit <2% solar is being claimed as containing Pop III stars

As the Roman Proposal Lead, I think I'm not allowed to ask folks to bet on the final number of submissions for #RomanCycle1 right? 🤔

🔭 Paper day! Ani Chiti + MAGIC discovery the first highly carbon-enhanced star in an ultra-faint dwarf galaxy. We suggest most CEMP stars form in such places. News article: news.uchicago.edu/story/ancien... Paper: www.nature.com/articles/s41... Arxiv version (updated soon): arxiv.org/abs/2508.04053

🔭 Storytime! This paper consumed my soul for a month and it turns out that you have to look at your 2D spectroscopic data. Thread... ui.adsabs.harvard.edu/abs/2024OJAp...

At ~$1 billion/day, the US has spent as much on the war in Iran in ten days as the entire FY25 budget for the National Science Foundation ($10 billion). Trump's FY26 budget request for the agency declined to $3.9 billion, due to a "realignment of resources in a constrained fiscal environment."

NSF–DOE Rubin Observatory 🔭 has issued its first scientific alerts, marking a historic milestone in astrophysics. Expected to increase to seven million alerts per night (!!!), these first alerts start a new era of dynamic, real-time observation of the night sky. More: noirlab.edu/public/news/...

Wise words from the hoardings on the building site of the new Graz Centre for Physics

The FCC just opened public comments on SpaceX's plan to launch a million satellites to do AI compute in space. Under the current proposal, an environmental review won't be required. Please consider submitting a public comment to oppose this damaging plan. darksky.org/news/two-sat...

Caltech astrophysicist fatally shot on porch in Antelope Valley; suspect charged with murder

🔥🐎 here we come!

After a year of protests from astronomers, authorities have abandoned plans for a giant, light-polluting renewable-energy facility in Chile’s Atacama Desert

First* stars** *many generations after Pop III **star clusters

Gotta find those PISNe

Good lord it has only been a week of 2026

After the killing of Ms Good, Greg Bovino of the CPB led a raid on a Minneapolis HS. An official there said: They don’t care. They’re just animals,” I’ve never seen people behave like this.” All MPLS schools now closed for the week. www.mprnews.org/story/2026/0...

Rocks are not a given!!

Slack really does not need to wish me happy new year especially once in every workspace good lord

NSF now planning to let POs largely decide what gets funded, and to send PIs reviews that are only 3-5 sentences long. They don't have to use outside reviewers (except maybe 1) and don't have to convene panels. (1/5)

Remember that lovely aurora last week? Well...um...this is what Euclid saw... 😱 🧵

Two very interesting papers about dark energy on the arXiv today, both very relevant to the ongoing interest in possibly evolving DE as suggested by the DESI results 🔭🧪 Here's the first and potentially more explosive one: arxiv.org/abs/2511.07517

Kyle Kingsbury is not a journalist. He is not an op-ed writer. He is a computer safety researcher. And he has written one of the most compelling, comprehensive accounts of the ongoing hell in Chicago that you could possibly imagine. In under 1600 words. aphyr.com/posts/397-i-...

More coverage of OSU’s new restrictions on conference attendance: “These conferences are open forums for us to present our work, network and collaborate. Telling us that they’re going to regulate whether or not we can participate feels very stifling, prohibitive,” said @ohdearz.bsky.social
