Astronomers spot planets beyond Milky Way for the first time
In a first, University of Oklahoma researchers have claimed to discover a population of planets beyond the Milky Way galaxy. The team observed about 2,000 extragalactic objects ranging from Moon to Jupiter mass in a galaxy 3.8 billion light years away. The discovery was made using quasar microlensing, where gravitational effect of small objects creates magnified images of faraway galaxies.
