It seemed that these redshifted galaxies were all moving away from the Milky Way. Hubble’s results suggested the farther away a galaxy was, the faster it was moving away from Earth. Hubble got ...

When that occurs, the newly found black hole in the dwarf galaxy may merge with Sagittarius A*, the supermassive black hole at the center of the Milky Way. This cosmic collision may remake our ...
