Our Public Talk this month is all about the mystery of Cosmic Dust From fragments of asteroids to cometary tails, the plumes of outer solar system moons and even debris from our own activities in space, the talk will have a bit of everything. ⏰ 6-7pm 📅 Tue 18 Nov 📍Burlington House, London 🎟️ FREE

Could the universe's expansion actually be slowing? 🌌 That's the suggestion from researchers at Yonsei University in South Korea, whose new study has been published today in Monthly Notices of the Royal Astronomical Society. Read more at: ras.ac.uk/news-and-pre...

The ageing of host stars can be catastrophic for planets! Our new research into this planet population shows that the evolution of stars causes giant planets to spiral into their host stars and be destroyed. Check out the press release below and paper (published in MNRAS today!) for more

Don't forget to look up later 👀 And not just for the fireworks! 🎆 You can enjoy the largest and brightest supermoon of 2025 tonight as our lunar satellite appears 8% larger and 16% brighter than average. 🌕 The only issue might be the cloud. But if you do get a good picture we'd love to see it! 📸

🚨New research alert🚨 Ever wondered what might happen to Earth and the other planets in our solar system when the Sun becomes a red giant in 5 billion years? ☀️🔴

Was great fun to help organise and co-chair this special discussion meeting at the @royalastrosoc.bsky.social Thank you to all of the speakers and attendees that made it such a great day! #astro #AGNOutflows

In London today for my first @royalastrosoc.bsky.social Council meeting at Burlington House as President Elect 🔭

Professor Sijacki is followed by Dr Rob Eyles-Ferris, of @physicsuol.bsky.social, who is talking about lobster eyes 🦞🫨 ... the Einstein Probe, and how the deaths of massive stars power the most powerful explosions in the universe. 💫💥 ⤵️

Today's Specialist Discussion Meetings have come to a close, but the talks haven't finished yet. October's A&G Highlights Meeting is now taking place, with RAS President Professor Mike Lockwood welcoming a packed room of attendees and introducing Professor Debora Sijacki. 👋 ⤵️

A series of talks and presentations have also been taking place at our other Specialist Discussion Meeting, about the seismic soundscape of the UK and Ireland. This 'UKI-Array' could support high-resolution imaging and research into geohazards, subsurface resources and net-zero goals.

First up in our black hole discussion meeting is a talk by Prof Debora Sijacki. 💫⚫ She says the field is moving in a "very exciting" direction, citing a "pioneering idea that black holes in dwarf galaxies could be driving powerful, fast outflows that could influence their star formation rates".

Let the discussions begin! 🗣️ Our first two Specialist Discussion Meetings of the 2025/26 season are about to start 🔭🌍 We look forward to welcoming everyone joining us in-person and online 👋

Looking forward to this tomorrow! I will be discussing my latest work, linking outflows, radio, and dust in DESI QSOs ✨
