For anyone in London next weekend - get yourself down to this absolutely wonderful combination of art & astronomy. It’s a really special place.
Honk, honk! We're also excited to say that a mesmerising mobile observatory bus known as 'Moon Palace' will be stopping off outside the RAS for a two-day visit this February. 🔭🚌

Designed for all ages, it has telescopes, out-of-this-world artwork, lunar maps & 'cosmic tea' in alien head mugs. 🎨🌘👽️

The future of fundamental physics research in the UK is under serious threat because of the massive government cuts to STFC funding. Please read this open letter by advanced fellows.

Very interesting to see this laid out by someone who was, until very recently, on STFC's Science Board.

Another positive is that the community response to the planned cuts 16 years ago actually had an effect. Some extra funding was found at the last minute. So, it is worth speaking out and pointing out these planned cuts will do a lot of damage to very active, and successful, research areas. 4/4

We're so excited to share the results of the ALMA large program ARKS that studied the distribution of dust and gas in a sample of 24 exoKuiper belts. With @lucaroundtheworld.bsky.social, Meredith Hughes and a large collaboration, we just published 10 papers presenting our first results arkslp.org

Well this is worrying. NASA has maintained funding for ADS but not SciX (a broader database). In response, management is planning to *close* ADS in Feb 2026, forcing all users to switch to SciX. ☄️🔭

We can see Io rotate slightly over the hour-long timelapse, tracking volcanoes on its surface!

And check out the Conversation piece for a cool slider showing how NGC 1068 lines up perfectly with previous data from LBTI.

Great to see our paper on methanol in TW Hya finally come out today (with Catherine Walsh and Jenny Calahan). A quick overview.... 🔭 ☄️ #radioastro

Today is a special paper day for me: for the first time we can do chemistry in a circumplanetary disk around a planetary-mass companion! Gabriele Cugno and I used JWST to tease out the signal of CT Cha b, finding a rich carbon chemistry (7 molecules + 1 isotopolog detected)! arxiv.org/abs/2509.15209

A very cool result! Julo+ with a paper on “Stellar halo subtraction … with integral field spectroscopy… on the PDS70, HTLup, and YSES1 systems” showing that the YSES 1b #exoplanet has a lot of emission lines - H alpha , H beta, He I, Ca H and K triplets, Na in absorption… oh my! #astrodon

I couldn’t agree more about those pretty public images… 😉

Sorry to have missed this great conference but huge thanks to everyone posting updates. It’s been great to follow along! #skao2025
Great #SKAO2025 conference summary from McClure-Griffiths. Ups: Community! Real SKA image/dishes! So much SKA Precursor science! Downs: Timeline, especially for MID. Lessons: Pretty public images matter, data is difficult, telescopes are always delayed.
