Finding new planets outside our solar system is nothing new these days. There are now 3,588 known exoplanets, as of February 1, 2018. Very recently, astronomers discovered for the first time ever exoplanets outside our galaxy! Obviously there are billions and billions of exoplanets in our galaxy and many more outside of our galaxy, but technological limits prevents us from seeing exoplanets outside our galaxy, until now.
Astrophysicists discover planets in extragalactic galaxies using microlensing
Wow! Odds are low that any of these planets, including this one outside of our galaxy, harbors life, let alone intelligent life, but one of these days, one of the planets we discover will harbor life. When that happens, I argue it will be the greatest discovery of all time. Astronomy never ceases to amaze me!!!
