Remember that loud bang last May? Colleagues at @haystack.mit.edu have used radar and acoustic data to track the meteor and reconstruct its orbit, from beyond Mars to the Cape Cod Bay arxiv.org/pdf/2610.24566 @universalhub.com

This is a diagram of the distance over time (based on latest orbital elements) of the two satellites from 16 Oct 00:00 UTC to 19 Oct 00:00 UTC

This is just terrible news. Helen was a very sharp and knowledgeable reporter, and I’ll miss her work:

Fab story from Margaret Hamilton, RIP, showing why Science-Mums are brilliant scientists! When innovating at the cutting edge of technology, it's so important to bring together a wide range of lived experiences. Sad that only ~20% comp-scientists are female 👩‍🔬🧪 ℹ️: www.theguardian.com/technology/2...

The Facial Expressions of Tethys by artist Julius von Bismarck. A suspended high-sea buoy that moves in real time. Sensors on a twin buoy out in the Atlantic Ocean send live satellite data to motors inside the museum. This makes the indoor buoy copy the exact, real-time movements of the ocean waves.

Critical Mass Boston - July 31st rolling from Copley Square at 19.00 Keep the safe-street momentum moving forward.....for Louisa. See you all there.

Never underestimate the bandwidth of a Toyota Yaris barreling down the highway with a trunk full of hard drives! Today I picked up the final set of data from the spring observing campaign of the @ehtelescope.bsky.social. Our black hole movie is in post-production!

An absolute masterpiece. Guy spent years making this and uploading dozens of videos on how, getting zero to 8 views each. I hope he can rack up more.

MIT Haystack Observatory’s SIMONe meteor radar network caught something at the same time that a loud boom was heard over eastern Massachusetts. Scientists are already analyzing the data!

OMB has a new proposal for the regulation of all federal grants, which would -deemphasize peer review -ban $ for publication costs and conference travel -make it easier to terminate grants we read the 400 page document (🫩) so you don't have to www.statnews.com/2026/05/29/n...

Of all the harm this administration has done to US science, today's proposed changes to the way federal grants are awarded and administered is the most damaging yet. The text of the federal register document is impenetrably tedious by design, so here's an excellent summary of what it says.

Welcome to the last half of the US federal fiscal year. Here is where we're at with National Science Foundation--the agency that funds basically everything other than biomedical research at American universities--grant numbers. grant-witness.us/funding_curv...

I highly recommend putting this NASA #Artemis II mission livestream on and just leaving it playing as you go about your weekend. Live views of the spacecraft, occasional visualizations of the current config, views of the control room, space-ground radio audio. www.youtube.com/live/m3kR2KK...

TLI! Translunar injection complete, Artemis II apogee now over 400,000 km; they're heading to the Moon.

The first deaths announced from the US-Israeli strikes on Iran: dozens of school girls. They hit an elementary school in Hormozgan.

Alex from our time working together, while he was in nursing school. Later, he moved to ICU, working as a nurse to support critically ill Veterans. He had such a great attitude. We’d chat between patients about trying to get in a mountain bike ride together. Will never happen now

kind of darkly funny that "gender studies" is the stereotypical "useless degree" because gender studies will help you understand a large and important chunk of the current psychosis in american life

Another Earth directed coronal mass ejection after an X1.2 flare eruption from sunspot region 4274. Arrival early on November 12 + strong geomagnetic storm expected.

I remember when the last American veteran of WWI died, and the newspaper quoted him remembering his time in London before being shipped off to France, and how he had watched a military paraded that included survivors of the Light Brigade

Scenes from bike trails in northern vermont

This is amazing: A direct image of the shadow of a black hole. A direct image of the hot, swirling gas circling and falling into it. And brand-new images showing an apparent magnetic flip around the black hole, a sign of turbulent, tumultuous changes. 🧪🔭 eventhorizontelescope.org/new-eht-imag...

Very sad news; it was a great privilege to work beside him in a small way.

Real time degradation in our weather forecasting.

Another huge self-inflicted loss.

This description would seem to explain a lot

There is a quasi-religion in Silicon Valley that views AI as godlike. This faith has always been parallel to Evangelical Christianity: salvation (transhumanism), the rapture (the technological singularity), and demons (Roko's Basilisk) Lately the AI faith has fully fused with Christian Nationalism.

Also spotted a sign that read "Vance ❤️'s Mrs Butterworth"

Spotted a snowy owl on Plum Island!

This is Vermont erasure!

Saw a human cannonball today!

It's been 12 hours so maybe everyone has moved on, but I created a graph with the all the missing lines. Visually, you could say White men without college degrees were ahead of 10 groups in 1980 (5th place out of 16), and only 7 groups by 2022 (9th place).

It's an open house night at Haystack Observatory! We're expecting over a hundred people...and maybe aurora once it gets dark
