The largest spot-the-difference effort EVER has begun!🚨
On the night of Feb 24, NSF–DOE Rubin Observatory officially released its first ~800,000 public alerts of detected changes in the night sky!🔍
A new era of discovery is here✨ 🔭🧪☄️

#February11 is International Day of Women & Girls in Science. So I would like to highlight Katherine Johnson, #NASA mathematician and computer scientist.

She was a trailblazer in the quest for racial equality and, as a champion of STEM education,
More on catastrophic cuts to UK astronomy & particle physics. Costs of facilities & international subscriptions go up so grants line and individual projects are cut. If the Government is serious about backing science & technology, they need to fix this. www.space.com/astronomy/uk...
Elon Musk et al are totally fucking up the night sky ALREADY and they plan to make it worse 🔭

Perhaps it was coincidental timing, but nothing underscores the collapse of the Washington Post like firing most of the Pulitzer prize winning #climate reporters the very same day as their opinion pages publishes a BS screed by climate misinformer Bjorn Lomborg.

Starts With A Bang podcast #125 – Large-scale structure
Here at the start of 2026, the biggest puzzles in the expanding Universe are the Hubble tension and the question of whether dark energy evolves.
Two cosmologists, me and Kate Storey-Fisher, discuss.

How recently have we understood the Universe?
The Universe has been around for 13.8 billion years.
But it's really only over the most recent millennia, centuries, and decades that humanity has understood it at all.

Brightest-ever lensed supernova reveals astronomy’s coming revolution
Astronomers found our first gravitationally lensed superluminous supernova.
With the Vera C. Rubin Observatory now operational, hundreds, maybe thousands more should be coming.

Very excited and honoured that we got funding for this exciting new research network with a fantastic group of people.

I haven’t seen this label used before but it seems apt. The video contains a good discussion of what “science populism” is and how it’s harmful.

Der Beschluss des Grünen-Parteitags gegen eine Erstattung von Homöopathie durch gesetzliche Krankenkassen ist ein wichtiges Signal. Es geht nicht (nur) ums Geld. Es geht auch um Abgrenzung: Was durch die Solidargemeinschaft finanziert wird, muss wissenschaftlich belegt sein. Die Erstattung führt…

I didn’t know it was this bad at Goddard. Infuriating. 🧪
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...!)

Speaking out for science ... My subjective conclusions to a short talk on "From Einstein to Astrology: On Misquotes, Scepticism, and Speaking Out for Science" at the VISESS doctoral school in Vienna
Enjoyed giving a short talk "From Einstein to Astrology: On Misquotes, Scepticism, and Speaking Out for Science" at the #VISESS doctoral school, remembering our open letter to Austrian public TV ultimately cancelling an astrology show. A small victory given the constant attacks on science...
