Webb Telescope Data Point To Six ‘Rogue Worlds’
17:03 minutes
Did you know that almost every star you see in the night sky has at least one planet orbiting it?
Here’s something even wilder: There are some celestial bodies that look a lot like planets, but just float around freely in the cosmos, unattached to any particular star. They’re called rogue worlds. With data from the James Webb Space Telescope, astrophysicists just identified six right here in our own Milky Way galaxy.
So what can we learn from these rogue worlds? Can they teach us anything about how stars and planets are formed? Guest host Rachel Feltman talks with two authors of the recent study: Assistant Research Scientist Dr. Adam Langeveld, and Professor of Physics and Astronomy Dr. Ray Jayawardhana, both of Johns Hopkins University in Baltimore, Maryland.
