Evolution over 25 years of SN 1987A at 9 GHZ, showing it growing bigger and w more details over time

Detail of SN 1987A w scale and beam size (resolution)

Happy s39th birthday to SN 1987A- the closest to us since the invention of the telescope! 🥳

Always a good excuse to share my cross stitch evolution over time in radio of SN1987A. Everything is to the correct scale etc bc cross stitch is the original pixel art.

Environmental protest group Extinction Rebellion says FBI is investigating it for terrorism Extinction Rebellion says some members have been visited by agents claiming to be FBI amid Trump’s threats toward liberal groups

Trump’s crackdown on environmental defenders and peaceful protestors - targeting groups like XR with FBI investigations - should concern us all.

Trump will stop at nothing to appease the billionaire polluters that helped get him elected. 🧪

It will be trivial to find LLM experts, possibly even LLM LLMers. The valuable astronomer will be the one who thinks outside the LLM box. The one educated to think astronomy as opposed to do astronomy. The doers will be 10/$ The saturation/dilution of knowledge problem is the one that concerns me.

It is always the case that the generation of people who can use the new tools appear to do better/output more, until they become the majority at which point the quality matters. The challenge of being closed loop on LLMs is the quality is no longer assessed. Thus the saturation effect.

Even aside from how do deal with LLMs, he has collected a dense set of pretty deep observations on astronomy and the astronomical community.

Why do we do astrophysics? At time of writing, large language models (LLMs) are beginning to obtain the ability to design, execute, write up, and referee scientific projects on the data-science side of astrophysics. What implic...

The deck of Paranal at sunset. Four 8-m Unit telescopes can be seen together with two of the four 1.8-m auxiliary telescopes. On the left the astronomers are enjoying the view of the sun set. On the right the sky is darker as the earth shadow rises.

It’s good to be home again. 🔭🧪

Congrats on the Plumian professorship.

I’m sure you’ll fill the enormous shoes with ease.

Good luck.

A splendid cold walk to Fiddlers Gill to see the fab but rusting Victorian #Braidwood Telescope! Once part of the now long-gone Lanark Observatory, its optics are safe at the Lanark Museum. Sadly I see no hope in restoring this beauty tho, that's been long-abandoned in this field ☹️ #histsci 🔭🏴󠁧󠁢󠁳󠁣󠁴󠁿

A pair of colliding spiral galaxies. Here, both spirals are shown face on, with the smaller of the two galaxies, IC 2163, at the upper left of the larger galaxy, NGC 2207, which dominates the center and lower right of the image. Both galaxies have long, spiraling, silver blue arms, dotted with specs of blue and red. Toward our upper left, the curving arms overlap, and bend toward their neighbors' core.

Happy belated birthday to JWST, which was launched on Christmas Day 2021. I hope it has many more years of transformative science ahead of it. 🧪

Who was Amelia Frank? The life of a forgotten physicist In the 1930s, this quantum mechanical pioneer faced obstacles that still confront women in physics today.

In 1977, American physicist John H. Van Vleck won the Nobel prize for his work on magnetism. In his Nobel lecture, amid a discussion of rare earth elements, one sentence leaps out:

"Miss Frank and I made the relevant calculations."
