Institute of Astronomy Cambridge

Next week, Cambridge cosmologists head to London for the Royal Society's Summer Science Exhibition!

From 30 June–5 July, the Kavli Institute for Cosmology will be at Carlton House Terrace with our Simons Observatory exhibit — exploring how we're using the Cosmic Microwave Background to uncover clues about the very first moments of the Universe.

Free and open to the public. Come say hello! 🔭

Professor of Astrophysics (1909) Hiranya Peiris has published a piece in the Bulletin of the Atomic Scientists on a structural gap in current AI safety frameworks — one that Forbes this week paired with Pope Leo XIV's encyclical on AI as two defining texts on the moment we're in.

Our 1909 Professor Hiranya Peiris appeared on The Life Scientific, talking to Jim Al-Khalili about pioneering the modern era of precision cosmology and revolutionising our understanding of the universe.

Our 1909 Professor Hiranya Peiris has a new Nature article out, titled "Large language models are not the problem".

If a Large Language Model (LLM) can replicate your scientific contribution, the problem is not the LLM. What does it say about our field that so much of the anxiety about AI comes down to the fear that a machine could do what we do? Perhaps it says we should be doing something better.
