This week, we welcome Dr. Dimitra Atri to the show. He is an astrophysicist from New York University Abu Dhabi, and we will be discussing his work showing how life might survive just beneath the surface of Mars, aided by galactic cosmic rays.We will also look at how astronomers found a type of black hole they always expected to find as well as one thought impossible. We examine the most detailed images ever recorded of the Sun, taken by astronomers at Europe's largest solar telescope. Lastly, we will journey to the Moon, where investigators recently found hematite – a mineral which forms from water and free oxygen – both of which are rare on the lunar surface.--- 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
