Jun 30, 2021 | Asteroids, Daily Space, Earth, Exoplanets, Mars, Neutron Stars / Pulsars, Supermassive Black Holes, Supernovae

About 900 million miles away in two different galaxies, a black hole and a neutron star merged, and their gravitational waves have been detected here on Earth. These detections add another type of merger to the collection so far discovered. Plus, new composition data on Mars’ south polar cap and a look back at the Tunguska Event. #AsteroidDay

Contrary to the destructive role supermassive black holes are thought to play in the lives of stars, it turns out that certain types of galaxies benefit from black holes clearing the way and keeping star formation going. Plus, lightning at the edge of space, a landslide in the Himalayas, and an interview with Dr. Darby Dyar and Dr. David Grinspoon about the recent selection of three different Venus missions.
