Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered three ultra-massive galaxies -- nearly as massive as our own Milky Way Galaxy -- already in place within the first billion years after the Big Bang.

Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe. This discovery from NASA's Chandra X-ray Observatory shows that very young black holes grew more aggressively than previously thought, in tandem with the growth of their host galaxies.

For some time after the big bang there were no stars. Researchers are now looking at cosmic dawn—the time when stars first popped into being—and are seeing hints of dark matter’s influence on supercold hydrogen clouds. News Writer Adrian Cho talks with Sarah Crespi about how this observation was made and what it means for our understanding of dark matter. Sarah also interviews Joanna Kaplanis of the Wellcome Sanger Institute in Hinxton, U.K., about constructing enormous family trees based on an online social genealogy platform. What can we learn from the biggest family tree ever built—with 13 million members spanning 11 generations? In a bonus segment recording during a live podcasting event at the AAAS Annual Meeting in Austin, Sarah talks with Michael Varnum of Arizona State University in Tempe about what people think they will do if humanity comes into contact with aliens that just happen to be microbes. Live recordings sessions at the AAAS meeting were supported by funds from the European Commission. This week’s episode was edited by Podigy. Listen to previous podcasts.
