Watching the Births of Solar Systems

Watching the Births of Solar Systems

Radio telescopes are delivering stunning images that, in some cases, current optical telescopes can’t equal. Witness the 20 beautiful protoplanetary disks imaged by the DSHARP team using the ALMA radio telescope in Chile. The diversity of these proto-solar systems is astounding. Principal investigator Sean Andrews will tell us how the pictures were created, and why they are surprising and delighting astronomers. Senior editor Emily Lakdawalla is literally looking back on objects around our own solar system. She tells us how backlit images reveal their secrets. The rubber asteroids have returned!
