We live in a big-city galaxy. The Milky Way is so big it has satellite galaxies that orbit it, just as the Moon orbits the Earth. These arrangements tell us a great deal about the secrets of the universe—from how galaxies ...

By conducting deep, wide-area imaging survey of the galaxy NGC 2403 and its environment, including the dwarf satellite galaxy DDO 44, astronomers have detected tidal tails emanating from the dwarf. The finding, presented ...
The universe is simply so vast that it can be difficult to maintain a sense of scale. Many galaxies we see through telescopes such as the NASA/ESA Hubble Space Telescope, the source of this beautiful image, look relatively ...
