Its exact value has been the subject of debate, but the Hubble Constant is an important figure in modern astronomy. Featuring Mike Merrifield from the University of Nottingham.
The Hubble constant tells us how quickly the universe is expanding and is usually quoted in really odd units. It also isn't actually a constant, and took many years to work out a reliable value for, and involved many arguments. Some groups thought it was around 100, others thought it was nearer to 50, and today we think it is about 67. So everyone wins!
Also discussing dark energy and gravity.

Black holes are a favourite of both science fiction and science fact. What are they though, and should we be afraid of them? How big would the Earth be if we wanted to make it into a black hole, and how big can they get? Is their terrible reputation really warranted?
Discussing the Schwarzschild radius.

You've heard of redshift, but what about the "blue shifting galaxy" on a collision course with the Milky Way!?
Featuring Michael Merrifield and Omar Almaini
Redshift is a measure of how fast objects in the distant universe are moving away from you. It is often used in astronomy as a measure of distance, because of Hubble's law which relates the redward shift in wavelength of the spectra of very distant objects to their distance and their epoch in the history of the universe.

How do stars and supernovae create the elements. Featuring Omar Almaini
Where do all the elements we know and love come from? The universe started with mostly just hydrogen and helium, so where is oxygen, iron, nitrogen, gold, silver and particularly carbon come from? Here we discuss some of the ways elements are made. Supernovas explode into the story.
