Marvelous new image of interstellar Comet 3I/ATLAS, taken by photographer Satoru Murata before dawn this morning.
On the right you can also see galaxy NGC 4691. There should be a lot more pictures coming in soon. 🧪🔭

Modern spectrograms are awesome but there is just something so cool about older ones like this.... Liu (1985) the signal from the May 18, 1980 eruption of Mt St Helens in China!

So fortunate to embark into the wilds of Northumbria and photograph rarely-seen, exotic British wildlife.

I've been walking the Hadrian's Wall Path this week and a few days ago I passed by the stump of the Sycamore Gap Tree. There are saplings sprouting up from the roots all around it in a race to become the next big tree.

The GBT is unparalleled in a lot of obscure astronomy subfields like astrochemistry and pulsars! If you want to support the nerds even nerds think are niche, help save the GBT!!!
Hey #science and #astronomy cats! This will start happening all over, but if www.gogreenbankobservatory.org strikes your fancy this is a great opportunity to help the world know more with direct impact.
If you can call, call. But if you can and want to give, GIVE.

A moment I still remember from undergad classes: in a discussion section for first quarter QM, another student complained that she was tired of the harmonic oscillator. The TA said, "I have some bad news," and then turned and wrote on the board:
Everything is a harmonic oscillator
Everything is a harmonic oscillator
Free, unsolicited advice for physics students: many things will go more smoothly for you if you can derive and explain the simple harmonic oscillator in your sleep
