Light gases like helium hung around in the gas-and-dust nebula that formed the solar system for only a few million years. "It's very much debated how long it took the Earth to form," Olson said.

NASA has launched the SPHEREx telescope to uncover the ingredients for life in our galaxy, as well as the PUNCH mission to study the sun’s mysteries.
