Astronomers Have Detected Planets Outside Our Galaxy

In an incredible world first, astrophysicists have detected multiple planets in another galaxy, ranging from masses as small as the Moon to ones as great as Jupiter.

Given how difficult it is to find exoplanets even within our Milky Way galaxy, this is no mean feat. Researchers at the University of Oklahoma achieved this thanks to clever use of gravitational microlensing.

Wow. I cannot even wrap my head around the numbers. Three point eight billion light years.

This is us.

Only 125,000 light years.
