Feature Guest: Vikram Ravi

They come to us from deep space. They last a tiny fraction of a second. They contain as much energy as the sun’s total output in 80 years. Yet we still haven’t figured out what causes these so-called Fast Radio Bursts or FRBs. I don’t want to say it’s aliens, but... no, it’s probably not aliens. Today we’re joined here at The Star Spot by Professor Vikram Ravi whose team is quickly zeroing in on the origin of these bizarre FRBs.

Current in Space

Amelia and Tony explain new research stating that worlds with completely frozen oceans, fittingly known as snowball planets, may actually be habitable . . . on the surface! And while the peak of the prolific Perseid meteor shower may have already passed, Simon reminds us that it's still not entirely over, and to get out there and take a look while you still can. Finally, robots are on the International Space Station! Joseph and Tony explain the purpose of three artificial helpers floating in the orbiting laboratory, one of which arrived only in late July.

About Our Guest

Vikram Ravi is Assistant Professor of Astronomy at the California Institute of Technology. He received a PhD from the University of Melbourne, then worked as the Millikan Fellow in Astronomy at Caltech followed by the Clay Fellow at the Center for Astrophysics at Harvard and Smithsonian. He describes his interest as exploring the “ephemeral, unseen universe,” studying phenomena that “vary on time-scales of nanoseconds to years.”
