Event Horizon Telescope Releases First Image of Sgr A*
In an early morning announcement, the Event Horizon Telescope collaboration finally revealed their first image of Sgr A*, the black hole at the center of the Milky Way galaxy. We have a special episode entirely about this amazing new image and the science behind it. And this week’s What’s Up is a total lunar eclipse.

Did we mention OSIRIS-REx sampled Bennu this week?
Of course, our top story today is the touch-and-go sampling event on our favorite asteroid-to-hate, Bennu. OSIRIS-REx’s TAGSAM worked as expected, and now we’re waiting for the mass measurement of the sample taken. Plus, the Milky Way’s black hole is spinning too slowly to make jets, and the galaxy’s history can be found in atomic hydrogen filaments.
Rocket Roundup for October 21, 2020
Join us for this week’s Rocket Roundup with host Annie Wilson as we look back at the launches that happened from the past week, including a suborbital launch from Blue Origin, more astronauts on their way to the ISS, and… another batch of Starlink satellites.
Betelgeuse smaller and closer than previously thought… what?
All of Betelguese’s strange behavior for the last year had everyone looking at the star, which the latest research shows is smaller and closer than previously calculated. Plus, InSight’s mole is finally all the way underground, new measurements of atomic hydrogen in distant galaxies, and two planets have been discovered around a red dwarf star.
Planetary Pandemonium for 16 October 2020
Join us for our weekly tour through the local neighborhood! This week we cover how the ice caps on Pluto’s mountains form; we celebrate BepiColombo’s flyby of Venus; and we continue to prep for that Bennu sample. Plus planetary scientist Alan Stern is going to space!
Exoplanet guardians, quasar jets, and a globular cluster
Today we look at three astronomical stories! First, simulations show that rocky Super-Earth sized exoplanets have a Jupiter-sized guardian. Then a study of over 700 quasars shows they form because of… magnetic fields, of course! And finally, spare observation time leads to the discovery of a metal-poor globular cluster near the Andromeda Galaxy.
Rocket Roundup for October 14, 2020
Join us for this week’s Rocket Roundup with host Annie Wilson as we look back at the launches that happened from the past week, including the Cygnus NG-14 mission (that included a new space toilet!), another SpaceX Starlink launch, and another Gaofen satellite from China.
