Taps microphone: anyone still out there? If you've been missing my tweets🤔come over to the blue skies - you'll find me there with the same handle. In the meantime here is me getting super excited about the Vera Rubin Observatory!
A world record-breaking digital camera is about to start making the first movie of the Universe. Astronomer Royal for Scotland Professor Catherine Heymans tells @SeanFarrington that this will be ‘the first time that we’ve looked at the Universe in this way.’ #R4Today

UK Election campaigning hits "silly season" with #Labour stating "the roads have more potholes than the moon has craters" 🧐 I'm on BBC 'More or Less' this week: way, way more craters than potholes. Still great if Labour is going to fix them tho! 📻: bbc.co.uk/sounds/play/m00208…
Labour will back drivers, by fixing up to one million more potholes every year and cracking down on soaring car insurance costs.

And in fairness to the Labour Party, there are more potholes in the UK than *named* craters on the moon. The @IAU_org has official names for 9176 lunar features, many of which date back to UK astronomer Mary Blagg's catalogue from 1913. ℹ️: en.wikipedia.org/wiki/Mary_A…

Sad news: Prof. Jasper Wall, titan and pioneer of radio astronomy, passed away on the 28th March. He created the 1st large-scale radio surveys to catalogue black hole quasars across the Universe and showed how to statistically analyse them to infer the cosmology of our Universe🧵

As the last Director of the Royal Greenwich Observatory, Jasper fought to stop its closure in the 1998 UKGov’s cost-cutting exercise.  Prevented from speaking to the media, Jasper said he could write a whole book about this sad period in UK astronomy. independent.co.uk/news/scien…

I met Jasper in his “retirement” as an Oxford researcher probing the large scale structure of the Universe with radio surveys.  We both moved to Vancouver and Jasper effectively adopted me, becoming surrogate grandad to my firstborn. He was v much loved and will be sorely missed.

#Aurora on Portobello beach Edinburgh 🏴󠁧󠁢󠁳󠁣󠁴󠁿. It was so very bright at one point that you could see the slow rainfall of colours across the sky with your very own eyes. Special thanks go to the Sun & atmosphere for putting on such a spectacular show for us tonight!!

The White House has directed Nasa to establish a unified standard of time for the moon and other celestial bodies 🌕 @AstroRoyalScot Prof Catherine Heymans tells #R4Today 'there are serious safety risks for communication and navigation' if a standard time can't be agreed.

A brief X-return to say how delighted I am to virtually join WorldCon 2024 #scifi. This will be the 1st time I return to "the stage" since falling ill with Long Covid ~2 yrs ago. Huge🙏 to the Glasgow team for making it possible for me to join in the fun with hybrid events.
Glasgow 2024 is excited to announce an online special guest! Prof. Catherine Heymans is the 11th Astronomer Royal for Scotland, appointed by Her Majesty the Queen in 2021, the first woman to hold this title in its 200 year long history. (1/14)

The one gift #LongCovid has given me: my dear friend @DrGrounds. And "what a small world" twist! Turns out her Dad wrote the book I taught myself A-level physics from, when I was off-school with #MECFS aged 17! DrG give me this 🎁today "an oak tree from this little acorn" 🥰❤️

Oddly enough, one of the best ways to learn about dark matter is through its interaction with light. (Gravitationally!) You can explore, and learn about, gravitational lensing in The Hunt for Dark Matter web app gravitational-lensing.explor…

Super Blue Moons! 🤗 the mismatch between "wow super rare event" media excitement and the prof astronomer "it's not actually blue and only slightly brighter than normal". Whatever whenever the moon is gorgeous so #dolookup - still pretty super tonight! bbc.co.uk/news/av/world-us-c…

Time to make a wish on a shooting star🌠: the Perseid meteor shower peaks over the next 48hrs. UK @metoffice forecasts patchy cloud tonight, but with even more clouds tomorrow, it's going to be blankets in the back garden tonight! rmg.co.uk/stories/topics/per…

Don't forget to turn off all your outdoor lights and give your eyes enough time (~15 mins) to fully adapt to the darkness.
