If we could go back 101 years, we would encounter a time when scientists still thought the Milky Way was the entirety of our universe. But, if we went back 100 years instead, we would find most ...

For the first time, the Hubble Space Telescope has detected a lone object drifting through our Milky Way galaxy. Two different teams of astronomers have arrived at separate conclusions about the ...
