On Truss & Kwarteng in ‘22. Allister Heath, Telegraph: “the best budget I have ever heard a British chancellor deliver". Alex Brummer, Mail: “a genuine Tory package elbowing to one side the Treasury's fiscal conservatism".
These men will now be paid actual money for their analysis of today’s budget.

We grabbed a timelapse of the comet C/2025 K1 (ATLAS) tonight at the Alston Observatory. This is the comet that has broken apart.

It is really moving. This motion is only over about 40 minutes.

NASA’s Europa Clipper captured this image of a starfield - and the planet Uranus - on Nov. 5, 2025, while experimenting with one of its 2 stellar reference units. These star-tracking cameras are used for maintaining spacecraft orientation.

Had a few enquiries recently about #Seestar smart-telescopes for #scicomm or xmas gifts for keen-kids. If you are lucky enough to have the cash (£369), these are a great investment & super easy to use.
👇These images were all taken in just a few mins in the light polluted city of Edinburgh. 🤩🔭

Well that’s a first. My only mildly sarcastic answer to a question about how we know 3I/ATLAS is a comet made it onto Have I Got News For You.

Quick update video on the real science (plus some hopefully not ill-informed speculation) of 3I/ATLAS around it's closest approach to the Sun.

Rapid brightening! Changing colour? non-gravitational acceleration! It is Aliens yet?

No. But it's still cool.

These are galaxy colour magnitude diagrams from a different article surely? 🧪🔭
I think this paper about the relationship between screen time and ADHD (and related brain structure) is very interesting... but at the same time, I'm looking at the plots and grind my teeth.
These are really terrible correlations (and possibly data biases). 🧪

Our interstellar comet has reappeared from behind the Sun! (I note there’s no sign of it having fired any engines while hidden from us….)
Comet 3I Atlas is back in the field of view of the PUNCH WFI instruments. Here is co-added stack of all of the images from the clear filter (centered around 550nm) from October 27th.

I made a (relatively) short video looking at the 8 reasons Avi Loeb thinks 3I/ATLAS has a 40% chance of being aliens.

I’m not impressed.

Welcome to our Open Day 👋

Unfortunately, due to the clocks change, our ANPR cameras have fined all Open Day guests who have parked in our car parks between 8-9am. The fines cannot be cancelled, but 5% will go back into improving the student experience.

Best quote referring to the comet going behind the Sun “Was this hideout planned as an opportune time for technological action?”… No 🔭🧪
Loeb latest: “If 3I/ATLAS is a massive mothership, it will likely continue along its original gravitational path and ultimately exit the Solar system.”

Getting his excuses in early. Even if moves like a comet and leaves the solar system it’s still aliens.

Irritated by all the publicity hungry nonsense about 3I/ATLAS and aliens I made a video describing what we actually know about this unusual tourist from deep space and deep time that is racing through our solar system.

Spoiler: it's a comet, a cool one, but still a comet.
