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. ☄️🔭 Funding info: ads.harvard.edu/adsug/2025/0... Transition plan: ads.harvard.edu/adsug/2025/0...

YEMS is hiring a postdoc to work on planet formation, exoplanet detection, high contrast imaging, and/or related topics. 🫸https://aas.org/jobregister/ad/811cf8bb

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 arxiv.org/abs/2510.04106

Methanol emission tracing ice chemistry and dust evolution in the TW Hya protoplanetary disk https://arxiv.org/pdf/2510.04106 John D. Ilee, Catherine Walsh, Jenny C. Calahan.

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 ☄

Sending my apologies to the reviewer for this one… 😬

It is well within the power of journalists to simply stop interviewing this individual

Lots of fun today at John Smeaton Academy talking all about science, art, radio astronomy & building planets onboard the amazing Moon Palace. Thanks for having us and for all the amazing questions!

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

First science talk at #skao2025 by Antonino Garufi about studying planet formation. Centimetre observations are critical to observing the growth of pebbles in planetary disks. 🧪 🔭 📡

We are hosting the 2025 UK & Ireland Discs meeting at the University of Hertfordshire (8-10 September). Topics include discs of all sorts, but especially protoplanetary discs and white dwarf debris discs. Abstract submission deadline is 15 May: ukidiscs.github.io/discs2025/ 🔭🧪⚛️☄️

Next we have Isaac Radley talking about a multiwavelength survey of the rho ophiucus star forming region, unveiling the hidden mass reservoir associated with planet formation. Data indicate that mass is present in larger dust grains. Radio surveys such as SKA will reveal more! #ukexom25

Here's a selection of illustrations I've created for science press releases over the years. Please repost for me! And if you need to commission this kind of work, check my background. I'm your man. #SciArt #spaceart

New paper, by Leicester PhD student @simintong.bsky.social. Simin presents a new set of models which show that compact protoplanetary discs are a natural consequence of so-called ``dead zones'': regions where disc turbulence is low. 🔭 arxiv.org/abs/2502.04452
