Hubblecast 64: It all ends with a bang!

Wed, 03 Apr 2013 12:00:00 +0200

Most stars in the Universe are small and insignificant, and they will -- eventually -- fizzle out without much drama. But a few light up the sky when they die, and in the process, they don’t just tell us about the lives of stars: they create the building blocks of life, and help us to unravel the whole history of the Universe. These are the stars that end their lives as supernovae, explosions that are among the most violent events in the Universe.

Hubblecast 53: Hidden Treasures in Hubble's Archive

Tue, 27 Mar 2012 17:10:01 +0200

Over two decades in orbit, the Hubble Space Telescope has made a huge number of observations. Every week, we publish new ones on the Hubble website. But hidden in Hubble’s huge data archives are some truly breathtaking images that have hardly ever been seen by anyone.

Hubblecast 52: The Death of Stars

Hubblecast 51: Star-forming region S 106

Thu, 15 Dec 2011 15:00:00 +0100

In this episode of the Hubblecast, we take a tour of the compact star-forming region Sh 2-106. Its hourglass shape is caused by the final, violent phases of a star’s formation in the middle of the gaseous nebula. This episode explains some of the science behind Hubble’s observations and brings them to life with detailed 3D computer visualisations.

Hubblecast 50: Q&A with Dr J

Tue, 25 Oct 2011 15:00:00 +0200

Hubblecast 42: Hubble's Greatest Hits

Thu, 27 Jan 2011 14:15:00 +0100

What makes a scientific discovery really important? It's partly down to how much scientists use the discovery in subsequent work -- but it’s also partly down to what inspires their imagination. In this episode, the Hubblecast talks to some leading astronomers about their favourite Hubble discovery. Meanwhile, our presenter, Dr J, struggles to make up his mind.
