UNAWE Space Scoop - Cotton Candies Floating in Space?

Astronomers just found something cool!  Typically, most Sun-like stars host planets between the size of Earth and Neptune called 'super-Earths' or 'sub-Neptunes'. These planets often orbit their stars even closer than Mercury orbits our Sun. They're mostly rocky super-Earths or they have a thick atmosphere and a rocky core and are sub-Neptunes. They're the most common types of planet found in our Galaxy. And yet, astronomers weren't sure exactly how these planets formed.  So yeah, they found something cool!    We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
