The Early Universe Was All About Galactic Hook Ups

In about 4 billion years, scientists estimate that the Andromeda and the Milky Way galaxies are expected to collide, based on data from the Hubble Space Telescope. And when they merge, they will give rise to a super-galaxy that some are already calling…

Andromeda and Milky Way Might Collide Sooner Than We Think

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.(…)Read the rest of Andromeda and Milky Way Might Collide Sooner Than We Think (740 words) © Bob King for Universe Today, […]

Disorderly Conduct: Andromeda’s Mature Stars Exhibit Surprising Behavior, Says Study

To a distant observer, our own Milky Way and the Andromeda galaxy would probably look very similar. Although Andromeda is longer, more massive, and more luminous than the Milky Way, both galaxies are vast spirals composed of hundreds of millions of stars. But new research presented at this week’s AAS conference in Seattle suggests that there are other differences as well […]

Dwarf Galaxies That Dance? Andromeda Observations Reveal A Larger Cosmic Mystery

What is up with these dwarf galaxies? A survey of thousands of galaxies using the Sloan Digital Sky Survey reveals something interesting, which was first revealed by looking at the massive Andromeda Galaxy nearby Earth: dwarf galaxies orbiting larger ones are often in disc-shaped orbits and not distributed randomly, as astronomers expected. The finding follows […]
