Ashes to Ashes, dust to dust: a search for the stolen starlight
6pm

Cosmic dust grains are usually a nuisance to astronomers because they block out star light, but dust is also the raw material out of which new stars and planets are born, and ultimately life itself. It is an important part of the Universe but astronomers are still not sure where all this dust is created. Using telescopes in space and on Earth in the last few years, we investigated whether titanic stellar explosions could be responsible for all the dusty mess in galaxies. It turns out that exploding stars can be efficient dust factories and could even be responsible for the very first cosmic dust in the universe. In this talk, I will show how the latest space technology is revealing a whole new dusty world.
