Live from MegaCon 2022 in Orlando, we team up with space reporter Brendan Byrne to discuss the image of the black hole at the center of the Milky Way, great discoveries in store with JWST, and the Mars Insight lander going out with a quake, if not a bang.
You've seen the pictures and read the stories, but to really know the gentle giant at the heart of the Milky Way, you've got to see the relativistic jets and accretion disks of Sagittarius A* for yourself. At only 27,000 light year from us all, Sagittarius A* features a modestly supermassive black hole producing a dazzling network of emissions and high-energy photons to light up your vacation, whatever your preferred wavelength of observation. Get get up off your a** and come on down to Sagittarius A*. Sagittarius A*, a journey that begins where everything ends (The Black Hole).
