Feature Guest: Stuart Ryder When a massive star explodes in a supernova, it tends to gobble up all the attention. But what happens when that star has a binary companion with its own story to tell? That’s exactly what happened last month when the Hubble Telescope captured the first image of the surviving stellar companion to a supernova, and it turned out to be more than just a passive observer. Today we’re joined at The Star Spot by the discovery team leader Stuart Ryder to tell us how sibling rivalry might account for the origin of one unusual type of supernova.  Current in Space Tony details the launch of a new space telescope that will take planet hunting to the next stage. Then Maya shares a tantalizing discovery from Jupiter's largest moon. And finally while we have trouble seeing individual stars in the galaxy next door, Dave reports on a star called Icarus that we just image despite it being 9 billion light-years away! About Our Guest Stuart Ryder is Head of International Telescopes Support at the Australian Astronomical Observatory and is responsible for coordinating Australia's usage of large telescopes around the world.
