New paper just out from my soon-to-graduate Ph.D. student Matthew Belyakov. He got JWST to look at 3I/Atlas in the mid-infrared. And there is water! and CO2! and CH4! and Ni! It's just a beautiful spectrum (and I love a beautiful spectrum). arxiv.org/abs/2601.22034 🔭

It's the things we do at the cutting edge of science that have brought the most unexpected leaps forward in progress in other areas of our world. Making scientific research align with government and industry priorities will miss out on the discoveries that will transform our worlds.

Haha, that's some amazingly strong signal from the thermal emission of the Ultra-Hot Jupiter KELT-9b! It allows measuring winds and actual comparisons with circulation models.

With the flood of (clearly) AI images everywhere, I'm getting more and more tempted to click on anything that's just Word Art and Comic Sans.

We’re getting so many journal submissions from people who think ‘it kinda works’ is the standard to aim for.
1. The thing about science that these jokers don't understand is that science cannot be vibe-coded.
Whatever its flaws, the point with vibe coding is that you're trying to quickly make something that sorta works, where you can immediately sorta see if it sorta works and then sorta use it.

It’s vibe coding, but for science.”

A rare bit of good news from the US. House republicans seem to be pushing back against Trump's huge proposed cuts to science.
NSF, NASA, NOAA - all look set to be near flat, or - for DOE - even a slight increase.

With the help of Gaia, some more cold Jupiters are found. They're at longer periods than the bulk of the known exoplanets, and at lower masses than most other known long-period planets.

Wow, I didn't know HCN crystals ("ice") could form cobweb-like structures. They look so cool!

Next week, I will start a course in science journalism. Exciting and a bit scary! Who knows what it will bring, but I will keep an eye out for nice commutable science jobs. And I might need some quotes at some point :)

JWST managed to determine the composition of three planets in the HR 8799 system. They found that the planets are all similarly enriched in heavy elements compared to the star, similar to Jupiter here. A bit surprising considering formation models.
