Lots of fun work out from APEx postdocs in the past week! first up was Sophia Vaughan @sophiavaughan.bsky.social on a deep search for reflected light from a hot Neptune w/ the VLT. This summed up light from ALL FOUR 8m telescopes over 2 nights- a preview of ELT-like data! arxiv.org/abs/2511.08691

But what about the ELT instruments themselves I hear you ask, how big are they? Well, dear reader, they are giraffe-sized and weigh four elephants #ExoELT 👀🦒🐘

It’s #ExoELT week! A week dedicated to discussing all things exoplanets and the ELT, @eso.org’s 39-m telescope coming online in 2029 😱 The size of this machine is just extraordinary. You can fit a whole VLT telescope on its Nasmyth platform 🤯

3I/ATLAS is the first interstellar object bright enough for amateurs to image: so fabulous to see the delight ☄️😍
I got it... I actually got it... Interstellar comet 3i, imaged from the middle of light-polluted Kendal, at 6am this morning, using my Seestar S50... This comet was already billions of years old before our Sun was even *born*... Very chuffed with this!

🤩 moving doors!
eso.org ESO @eso.org · 16d
Open Sesame!

The ELT doors have moved for the first time. This was no small feat, as each door will weigh 650 tonnes once completed.

The ELT dome & its doors will guard the telescope from the harsh conditions of the Atacama Desert.

Happy 30th discovery day 51 Peg b! We're at Observatoire de Haute Provence where it all happened, listening to Michel Mayor & Didier Queloz tell us all about that extraordinary radial velocity discovery with ELODIE on the 1.93m in 1995 and the incredible exoplanet science that followed. What a day!

1/ A rising telescope under a rising Sun and Moon! 🔭☀️🌕

This montage is a kaleidoscope of moments from the construction of our Extremely Large Telescope.

Creating this #ELT collage took Boris Häußler, an ESO astronomer in Chile, years of meticulous planning.
