SpaceTime: Your Guide to Space & Astronomy S27E77: Early Universe Black Holes, Mars' Odd Rocks, and Milky Way Flares

Join us for SpaceTime Series 27 Episode 77, where we explore the latest cosmic discoveries and advancements in space exploration.
First, astronomers have discovered the earliest known pair of quasars in the process of merging. Reported in the Astrophysical Journal Letters, this discovery represents the earliest known merger of supermassive black holes, occurring just 900 million years after the Big Bang. This period, known as the cosmic dawn, is crucial for understanding the formation of the first stars and galaxies and the epoch of reionization.
Next, NASA's Mars Perseverance rover has discovered oddly textured, popcorn-like rocks in a formation known as Bright Angel. These rocks suggest the presence of groundwater in Mars' past, and mission managers plan to conduct detailed exploration to uncover their origins.
Finally, new insights into the Milky Way's supermassive black hole, Sagittarius A*, have been presented at the 244th meeting of the American Astronomical Society. Using decades of x-ray data, astronomers have uncovered previously undetected flares and echoes, providing valuable information about the black hole's environment and past activity.
