Maciek Wielgus - A Glittering Black Hole in M 87 - Astronomy News with the Cosmic Companion Oct 13, 2020
An odd glitter is seen around the supermassive black hole in M 87 - and we talk to an astronomer who found the strange lights.
Hello everyone:
This week, we are joined by Dr. Maciek Wielgus, astronomer at Harvard University, speaking to us from Gdansk, Poland. We will discuss his work revealing glittering around the supermassive black hole at the center of the M 87 galaxy.
But first, we look at a new study identifying 24 exoplanets that appear to be even friendlier to life than Earth. We also see how superflares – powerful eruptions from stars – behave, and learn how they might affect life on other worlds. Then, we take a look at OSIRIS-REx, NASA's first attempt to collect material from an asteroid, as the revolutionary spacecraft readies to touch the surface of the asteroid Bennu.
