Astronomers may have found the first-ever exomoon seen by humans

Geek- We’re living in an age where astronomers can find exoplanets that we can’t actually see. What we haven’t seen yet though, is an exoplanet’s moon, as they’re much smaller than the exoplanets themselves. Now, though, astronomers at University of Notre Dame claim they have seen the human race’s first-ever exomoon.

The story is too old to be commented.
