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.--- Send in a voice message: https://anchor.fm/the-cosmic-companion/messageSupport this podcast: https://anchor.fm/the-cosmic-companion/support Get full access to The Cosmic Companion at thecosmiccompanion.substack.com/subscribe
