Spacetime With Stuart Gary

In this episode of SpaceTime, we dive into the cosmos to uncover the secrets of the early universe, explore the potential for black hole atmospheres, and examine the intriguing history of habitability on Mars, alongside the launch of a new deep space antenna by the European Space Agency.Mysterious Red Dots in the Early UniverseAstronomers have identified a population of enigmatic red dots in the early universe, potentially representing exotic stellar atmospheres around ancient black holes. These findings, published in Astronomy and Astrophysics, could bridge the gap in understanding the rapid growth of supermassive black holes. The Webb Space Telescope's observations suggest these objects might be a new class of celestial body, challenging existing models of galaxy formation and offering insights into the origins of galaxies.Multiple Episodes of Habitability on MarsNASA's Perseverance rover has provided compelling evidence that Mars's Jezero Crater experienced multiple episodes of liquid water flooding, each
