Two colliding galaxies have been found to be reorganizing their dwarf satellites, potentially solving a major conundrum ...

They orbit the Milky Way at a distance of about 160,000 light-years and are visible from the Southern Hemisphere without a telescope, according to NASA's Goddard Space Flight Center.

Astronomers have long predicted that a collision between our galaxy and nearby Andromeda could be inevitable, but new ...

New evidence suggests that a dwarf galaxy orbiting the Milky Way called Ursa Major III is actually a star cluster.

Astronomers identified what they believed was a lone brown dwarf orbiting a bright single star. Then they looked more closely.

S29 and S55, we can only assume, will meet the same fate at some point. The post Here’s How Stars Orbit Milky Way’s Supermassive Black Hole appeared first on Nerdist.

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies ...

But these and other more exotic possibilities were eliminated in the spring of 2002 when a star called S2 swept down in its highly eccentric orbit and passed within 17 light-hours of the Milky Way’s ...

Hubble’s latest portrait of the Tarantula Nebula reveals a turbulent star-making region far beyond the Milky Way. Located 160 ...

Astronomers have spotted a star dancing around a massive black hole in the middle of the Milky Way galaxy — and they said it proves Einstein was right. The star is the first ever caught circling ...

Yet observations suggest that many galaxies don't do this. Many of the Milky Way's dwarf galaxies, for example, orbit it in the same direction along a narrow plane.
