Walkabout the Galaxy
Supermassive black hole; atoms; star formation rates; Voyager 2
Astrophysics and Astronomy | Physics
Yes, it's just as bad as the title suggests, because when a supermassive black hole in a galactic center really gets going it can shut down star formation in the galaxy by blasting out all the raw star materials also known as atoms. The astroquarks explore galaxies with large and small star formation rates, plus we catch up on space news with Voyager 2 and the return to the Moon, and some throwback Voyager trivia.
Black Body Radiation
Don't be deceived by our unassuming name, blackbody radiation is the brilliant illumination that brightens your day. For stars, planets, asteroids, and even people, blackbody radiation provides a simple, one-stop shop to describe the spectral radiance. Give blackbody radiation a temperature, and we'll give you photons from gamma rays to microwaves. Blackbody radiation also provides an excellent return on your investment: double your temperature, and we'll deliver a whopping sixteen-fold increase in your radiation return.
