Supernovae and Galaxies Being Used to Solve Astrophysics’ Biggest Questions

Supernovae and Galaxies Being Used to Solve Astrophysics’ Biggest Questions

Two new studies are attempting to solve a couple of big puzzles in astrophysics: Is the Hubble constant actually constant? And why do galaxies have flat rotation curves? Plus, a young star’s circumstellar disk, the search for stellar-mass black holes, magnesium in the deep waters of Neptune and Uranus, and an interview with PSI scientist David Horvath regarding possibly active volcanism on Mars.

Tiny ‘Unicorn’ Black Hole Found in Milky Way is Closest One to Earth

A tiny black hole, only three solar masses, has been found inside the Milky Way in the constellation Monoceros. One of the smallest black holes ever found, it is also the closest one to Earth. Plus, Perseverance, Gaia, a brown dwarf, new images of Jupiter, seismic monitoring from space, and this week’s What’s Up.

Gas giant found orbiting white dwarf star and a Wolf-Rayet binary produces dust

Join us today as we take a look at today’s top story – a planet has been found still in orbit around its white dwarf star even after a supernova. Then we discuss how a Wolf-Rayet binary system is a dust factory. Finally, new works show neutron stars are NOT producing all those heavy elements, the solar minimum is over, Plus special guest, Sara Seager from MIT.
