The Milky Way and Andromeda during the merger—a close up. Credit: ICRAR Astronomers have discovered that our nearest big neighbor, the Andromeda galaxy, is roughly the same size as theMilky Way. It had been thought that Andromeda was two to three times the size of the Milky Way, and th...
Scientists say there's a 50/50 chance that our Milky Way galaxy will collide with the Andromeda galaxy, challenging previous certainty about this cosmic event.
Both the Milky Way and Andromeda are moving together in the direction of what's called the Great Attractor, theUniversity of Hawaii Institute for Astronomyreported. The Great Attractor is thought to be the center of the Laniakea Supercluster. However, observations of this region of the local univ...
At the same time, these models predict that the size-luminosity distributions for satellite galaxies around similar host-halos must be the same, providing a natural explanation as to why the size distribution of Milky Way and Andromeda satellites are similar. Although strong rotation is currently ...
3.Andromeda, the largest galaxy in the Local Group, is one galaxy that can be seen - at least partially - with the naked eye.4,The Milky Way is the second largest galaxy, followed by the Triangulum Galaxy. The Local Group contains about 50 galaxies, most of which are...
People always seem fascinated that the Milky Way Galaxy and Andromeda Galaxy are going to merge. I've always loved explaining it to people. I even have a PowerPoint presentation about it. But now I've learned that it might not happen (Astronomy magazine, Jan '25 issue page 9). What shou...
Our Milky Way galaxy is a cannibal. It has grown by consuming other galaxies. Yet, it too, may be destined to collide and merge with an even bigger galaxy: Andromeda. Though galaxy collisions are normal events and NASA suspects this collision is inevitable (in billions of years), new ...
The Milky Way is classified as what kind of galaxy? What is solar nebula? Is Polaris a circumpolar star? What constellation is the Orion nebula in? What galaxy is shaped like a pinwheel? What is the Andromeda constellation? What is the Andromeda Galaxy made of?
If the universe is expanding and everything in it is traveling at the same speed, why would galaxies collide, as the Milky Way and Andromeda are projected to do? James Rains, Concord, California There’s a competition between the expansion of the universe and the gravitational ...
What lies at the far reaches of the universe? This is a question that science has yet to answer, but most young people in China today already have an answer. According to them, at the end of the universe is not the Milky Way, the Andromeda Galaxy or the Canes Venatici Constellation, ...
