It's publication week for my newest children's book, The Great Alien Hunt 👽 I'm really excited about this one. Readers will be able to join the quest to find habitable planets and signs of life across the Galaxy when it comes out on March 6th! 🔭🧪

This is obviously getting less airtime than normal on account of The Horrors, but it’s incredibly cool and exciting that within weeks people will be going back to the Moon after more than half a century

Had an intriguing editorial discussion recently: how did people in the past talk about 'minutes' when they didn't have watches or standardised times? How does that affect your thinking?

Come down an Elizabethan/Jacobean rabbit hole with me.

The train company website insists my journey isn’t delayed, even though it knows my train got in at 9:57, and the connection left at 9:56. Glad to know LNER thinks I can literally time travel

I’m going to be in Northern Ireland this February, talking about the search for alien life across the galaxy! If you’re around in Belfast, please come along 😀👽

Eww why is the Guardian running advertorials for Macdonalds. These fake paid-for articles seem so much more pernicious than just regular ads

100%. When I post about astronomy or books here, I get nice replies talking about astronomy and books. On X I get people telling me space is fake, NASA is lying, and people running crypto scams. Pretty easy choice
"Bluesky is an echo chamber."
"Bluesky doesn't have enough reach"
"Liberals must return to X to challenge the far right"

I'm not a tech bro or a journalist. Your priorities are not my priorities. Stop telling me I need to do anything other than chat about comics & telly with people who seem nice.

Amazing lunar halo last night — a treat for everyone at our public stargazing evening in Cambridge! 🧪🔭

It was a huge pleasure to be back at the Royal Institution last month! I gave a lecture all about the mysteries of dark matter, which is now up on YouTube. 🧪🔭

(As a bonus, my demo actually worked, unlike in my 2021 Ri talk...!)

Woke up to an unsolicited email laying out a radical new theory that explains why quantum mechanics, relativity, and LCDM are all wrong.

It started "I know this sounds like an email you'd get from a nutcase. But I'm actually a 75 year old electrical engineer!"

What is it about retired engineers?

This also totally fails to account for different fields having different norms. In astronomy, the last author slot is meaningless (and is almost certainly someone who didn’t contribute all that much). 🔭🧪
🧪For those of us who do complex collaborations with multiple corresponding authors this is terrible . I suspect it will also hit female authors disproportionately as they tend to have more collaborations across fields…https://www.nature.com/articles/d41586-025-03281-4
Google Scholar tool gives extra credit to first and last authors
Researchers welcome the initiative, but say it doesn’t go far enough to capture the nuance of researcher productivity and impact.

On the contrary, Cornell et al. (1994) was way ahead of its time, positing the existence of quasi-stars (en.m.wikipedia.org/wiki/Quasi-s...) which mainstream astrophysics didn’t predict until 2006.
If I learned anything from the song Black Hole Sun it's that Chris Cornell didn't know shit about astrophysics
