Nothing like a call to go on BBC news to shake up a relaxing Sunday morning! I spoke about all things Nancy Grace Roman — how powerful it is, the amazing discoveries that await us, and the fact that all the data will be completely public. Bring on the launch :)

After trying a few, my absolute favourite (even better than a sharpie!) is a Pilot V Sign Pen. It’s literally perfect. Thin and glides like a dream, and no bleed through 😊📖

A pilot V Sign Pen, the best pen for signing books

It's publication day for Mastering the Multiverse, the latest instalment of the Supervillain Academy series from @dkbooks.bsky.social! Black holes, time travel, wormholes, dark matter, and the big one: do we actually live in a multiverse? Available everywhere books are sold 😀🧪🔭

I have a new book coming out next month -- my children's astronomy books have become a trilogy 😀 Want to know about time travel, black holes, wormholes, and whether we live in a multiverse? Mastering the Multiverse is out May 7th, and available to preorder now. 🔭🧪 dk.com/products/978...

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

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

By popular demand, a side-on view of the glass gravitational lens! Now with extra autumnal-ness. 🧪🔭

It is regular glass optics, but it’s a piece of glass specifically made so the lending matches the gravitational lending profile of a galaxy. This video shows it a bit better

GPT5 now knows how many 'r's are in the word strawberry. But this seems like a one-off, and fails on similar words. Has the 'how many 'r's in strawberry' question become easy just because it's now part of the training data?

It was amazing to be part of the Read For Good 2025 Summer Party, alongside so many great authors and illustrators. We went live to 65 schools around the UK, and spoke about scary unicorns, anxious doughnuts, and alien life across the galaxy. Fun times!

It was so great to speak at Cheltenham Science Festival (in one of the biggest venues I’ve ever spoken in!). Hundreds of super keen students came to talk all things extraterrestrial life, as part of the Great Alien Hunt book tour 👽🧪🔭

People talking with ChatGPT and thinking it’s conscious are basically doing the human version of this

It was fun talking about my new book at the Oxford Literary Festival 😀 As always, the questions were amazing (including one very precocious ten-year-old who was very sceptical about the detection significance of certain exoplanets, which blew my mind.) Get the book: www.dk.com/uk/book/9780...
