Astrophysicists have discovered for the first time a population of planets beyond the Milky Way galaxy. Researchers were able to detect objects in extragalactic galaxies that range from the mass of the Moon to the mass of Jupiter.
Two red dwarfs and their accompanying gas giant were discovered through a microlensing event -- but their true nature could only be confirmed by Hubble.
There is a peculiar system 1,600 light-years from our solar system. It is composed of two brown dwarfs, massive objects too big to be planets and too small to fuse hydrogen and become stars. But that is not the strange part: Scientists have now discovered a Venus-sized planet around the smaller brown dwarf.
