6:46Now PlayingIn this conversation, Neil deGrasse Tyson, co-host Chuck Nice, and Harold Connolly Jr. discuss the growing scientific evidence for the chemical ingredients of life on Mars and asteroids. The discussion explores Martian minerals like gypsum and phosphate-rich deposits, possible ancient water activity, organic compounds discovered through the OSIRIS-REx mission, and whether these findings could point to past microbial life on Mars — while also debating abiotic explanations versus true biological evidence.
