Feature Guest: Sandro Mereghetti
Fast radio bursts are a new mystery in astronomy. These highly energetic events of unknown origin were first discovered in 2007 out in deep space. Now a team is reporting the first fast radio burst to emanate from our own Milky Way Galaxy. Today we’re joined here at The Star Spot by Sandro Mereghetti, whose team is on the hunt for the source of this unusual phenomenon.

Camilla shares the remarkable discovery, or rather re-discovery, of the heartbeat of a supermassive black hole in a distant galaxy, found still alive and kicking ten years after being first observed.

In other black hole news, Finally, Jeff brings us back down to Earth (though still above Earth), as SpaceX is launching ever more Starlink satellites into orbit to provide high-speed Internet coverage to citizens of our planet. There’s only one problem: the future of ground-based astronomy may be at stake.
