Synopsis

Feature Guest: Roberto Abraham Imagine a galaxy that has a similar mass and volume to our own but where somebody turned off most of the stars. Meet Dragonfly 44, the most famous member of a new category of galaxies known as ultra-diffuse. Are they failed galaxies, bits of other galaxies or something even stranger. Today we’re joined at The Star Spot by Professor Roberto Abraham whose team was responsible for the discovery of what’s being dubbed the Milky Way’s Dark Matter Twin. Current in Space The killer asteroid that took out the dinosaurs - and much of life on Earth - came from somewhere in our solar system, and Anuj reports we’ve just identified its home base. Then in case you thought the universe was a big place Tony explains how our observable universe just got a whole lot bigger. And did you know Earth has at least one sidekick? Dave explains how a new mission will help study so-called Trojan asteroids that share a common orbit with our pale blue dot. About Our Guest Roberto Abraham is Professor and As
