A team of astronomers working with the James Webb Space Telescope (JWST) announced the discovery of six rogue planet candidates in an unlikely spot.
The planets, which include the lightest rogue planet ever identified (with a debris disk around it), were spotted during Webbs deepest survey of the young nebula NGC 1333 , a star-forming cluster about a thousand light-years away in the Perseus constellation.
These planets could teach astronomers a great deal about the formation process.
Webb observations indicate that rogue planets account for about 10% of celestial bodies in the targeted cluster.
The data will help astronomers refine their estimates on the number of rogue planets in our galaxy.
At 10% that would suggest that there are anywhere from 90 to 360 billion rogue worlds floating out there.
