Water Detected in Planet-Forming Disk Around Baby Star

Posted by in category: space

One of the most interesting baby planet systems in the Milky Way has just yielded a detection of water vapor.

And not just anywhere, either. In the extended disk of dust and gas that still clings to the star PDS 70, the James Webb Space Telescope detected the molecular signature of water in the region expected to form Earth-like worlds.

This could help us work out how Earth formed, and where its water came from; but it also is a tantalizing clue about the formation of other potentially habitable worlds out there in the wider galaxy.
