My latest @science.org water cooler piece, on the arrival of our 3rd interstellar visitor, 3I/ATLAS. As an extragalactic astronomer I am an amateur, but comets are amazing, and interstellar comets even more so. There may be 10^26 of them in the Milky Way www.science.org/doi/10.1126/... #astronomy
Interstellar visitors: Smoking and nonsmoking
As a third interstellar visitor, the comet 3I/ATLAS, has entered the Solar System, there is a huge community effort underway to study it.

Thank you
@empirepoduk.bsky.social for the wonderful history of Gaza. As I listen I keep finding locations on Google Maps. Finding pre-war images of beautiful parks, beach resorts, shopping centres etc has also been eye opening - so much beauty, green spaces, and joy!

The donation box at the National Library of Scotland is almost all dollars. I guess we expect libraries and museums to be free and Americans don’t?

Inspiring conversation between Sally Magnusson and Tim Berners-Lee @timbl.bsky.social at Assembly Rooms tonight. Closed with "practice creativity, practice collaboration, practice compassion". Maybe TBL should make that a T-shirt and include it with his book "This is for Everyone"

Curmudgeon Time. I hate the fact that my Apple devices now always have to be in a chosen "focus". You can't choose "no focus". I created a new one called "none" just for a larf but it's not the same.
