Just like the moon orbits the Earth, and the Earth orbits the sun, galaxies orbit each other according to the predictions of cosmology.For example, more than 50 discovered satellite galaxies orbit our own galaxy, the Milky Way. The largest of these is the Large Magellanic Cloud, or LMC, a large

Not long ago, the center of the Milky Way exploded
Will Andromeda start consuming the Milky Way?
Scientists have now charted the cannibalistic past of the neighboring galaxy to our own - Andromeda. The large galaxy now appears to have sights set on the Milky Way as its next main target.By pulling together big data, astronomers have figured out that Andromeda has, over time, consumed several smaller
“Stellar baby boom” may have given birth to half the Milky Way’s stars
Hypervelocity alien stars could be invading the Milky Way
Astronomers have discovered a population of incredibly fast-moving stars bearing down on the Milky Way. It is possible that these newly found "hypervelocity" stellar bodies were created in another galaxy, before being hurled out into intergalactic space on a collision course with the Milky Way.Our galaxy is populated by over
Four newly discovered Milky Way neighbors
Ultra-faint dwarf galaxies are the smallest, most dark matter dominated, and least chemically enriched stellar systems in the universe, and are important targets for understanding dark matter and galaxy formation. They comprise by number the majority of galaxies in the universe, and not least, dwarf galaxies around the Milky Way
An ‘Invisible Galaxy’ May Be Hiding in the Milky Way
Scientists think that at the heart of nearly every galaxy, including our own Milky Way, lies a supermassive black hole (SMBH) with immense gravity. These SMBHs are surrounded by dense clusters of millions of stars and—according to findings published earlier this year—probably thousands of smaller, star-sized black holes that all orbit within a few
Our Galaxy Has Already Died Once. Now We Are In Its Second Life
Magnetized inflow accreting to center of Milky Way galaxy
Are magnetic fields an important guiding force for gas accreting to a supermassive black hole (SMBH) like the one that our Milky Way galaxy hosts? The role of magnetic fields in gas accretion is little understood, and trying to observe it has been challenging to astronomers. Researchers at the Academia
How Long Would It Take to Cross the Milky Way at Light Speed?
Andromeda and Milky Way Galaxies Are Already Touching
The merger of the Milky Way and Andromeda galaxy won’t happen for another 4 billion years, but the recent discovery of a massive halo of hot gas around Andromeda may mean our galaxies are already touching. The Andromeda Galaxy is the largest member of a ragtag collection of some 54 galaxies, including the Milky
