Check out Chris Lintott discussing this lecture and your unanswered questions on our brand new podcast "Any Further Questions?' available on Apple and Spotify
******
There have been two major revolutions in how we look at the sky - the shift beyond the optical to other wavelengths, particularly the radio, and the increasing attention paid to how objects change over time.
We start with the discovery of pulsars by Jocelyn Bell Burnell, explore how a microwave oven bamboozled astronomers, and discuss the latest research on Fast Radio Bursts, mysterious events detected in galaxies billions of light-years away.
This lecture was recorded by Chris Lintott on 21st February 2024 at Barnard's Inn Hall, London
Chris is Gresham Professor of Astronomy.
He is also a Professor of Astrophysics at the University of Oxford, and a Research Fellow at New College.
The transcript and downloadable versions of the lecture are available from the Gresham College website:

A superb lecture - great to hear about the many observations we still don't understand; there is loads to learn from this method of observing the universe

Nah, the aliens will look at that probe image and say 'Aww, look, they were so primitive they didn't know about their Oort Cloud yet. They thought that little thing was a planet'

I still remember the end of that one Battlestar Galactica episode, where Apollo sits in this observatory, and then just after he leaves, it receives footage of the moon landing.

Maybe I have the mental capacity of 1 billion super computers, or should I just say I'm really smart, but I find it very useful to have some thing concrete to compare the density of neutron star material to. Saying it's really heavy or really dense could just mean more dense than usual. I don't think it would be very helpful to say some thing like neutron star material is very dense and whatever black holes are made of is very very dense.

1 thimble of neutronium (Thats the material neutron stars are made of) would weigh as much as a mountain. A black hole with a thimble sized event horizon would weigh about the same as the moon. There u go, quantified it for you

Your just-after-the-lecture-starts promo plug exhorts the viewer to share. Unfortunately that intrusive just-after-the-lecture-starts promo plug is the very thing that has *_stopped_* me sharing on social media. *_Put it at the end!_*

If it was at the end you would not have heard it. That is why the speaker explains in a sentence or two what his lecture is about. That is an opportunity to decide to listen or not.
