Euclid is finding free floating planets in Orion, too

There are likely millions of "rogue" or free-floating planets (FFPs) spread through the galaxy. These planets, which aren't big enough to become stars but also aren't beholden to a star's gravity, are some of the hardest ...

Galactic bloodlines: Many nearby star clusters originate from only three 'families'

An international team of astronomers led by the University of Vienna has deciphered the formation history of young star clusters, some of which we can see with the naked eye at night. The team, led by Cameren Swiggum and ...
