James Webb finds interstellar ice older than its host star

Bookmark this story

Observations from the James Webb Space Telescope show that ice in a planet-forming disk predates the star it orbits. The finding indicates some of the solid materials that build planets can survive the radiation and collisions of star formation, preserving a record of conditions before the system formed.
