Building Andromeda: Galaxy ended with right-angled stars

The large galaxies present in the present universe were not always that large. There are indications that over time they have mainly been formed by collisions with other galaxies. These collisions have left traces that we can still discover: stellar streams attracted by the victims of the collisions, and weak dwarf galaxies that still orbit the larger object that has …

Apparently, the Andromeda galaxy is a monstrous cannibal that eats smaller galaxies

M31, the Andromeda Galaxy, with its companion galaxies. VW Pics The Andromeda Galaxy is officially a monster. Astronomers studying our neighbors have discovered that the huge spiral galaxy certainly has a cannibalistic past. Andromeda has devoured galaxies twice smaller in the last 10 billion years, but the way they were devoured confused astronomers. Our galaxy is warped and twisted but …

This is what it will look like when the Milky Way and the Andromeda galaxies collide billions of years ago

What happens when two galaxies collide? The Milky Way and the Andromeda Galaxy are on a collision course and will meet in about 4.5 billion years. Now astronomers using the Hubble have visual insights into what this collision might look like. When two galaxies collide, it is very unlikely that stars will actually collide with each other. The distance between …

Thanks to Gaia, we now know exactly when we will collide with Andromeda

Astronomers have known for some time that the Milky Way and the Andromeda galaxies will collide at a later date. The best guess for this rendezvous was in about 3.75 billion years. Now, a new study based on Data Release 2 of ESA's Gaia mission brings clarity to this future collision. The overall picture of the collision contains more than …

We finally know when the Milky Way will break into the Andromeda galaxy

(Digital India) Our Milky Way will survive a little longer in its current form than some astronomers had thought, suggests a new study. The monster collision between our Milky Way and the other spiral galaxy Andromeda will occur about 4.5 billion years ago, according to new research based on observations of the European Gaia spacecraft. Some prominent earlier estimates had …

The Andromeda Galaxy will hit our Milky Way later than expected

Astronomers have long suspected that the colossal Andromeda galaxy would collide with our modest Milky Way in billions of years. The collision was predicted in about 3.9 billion years ago. After analyzing new data collected by the European Space Agency's star-gazing satellite Gaia, astronomers now set the date to 4.5 billion years – 600 million years later than originally anticipated. …

Andromeda finally comes for our Milky Way

The apocalypse has been postponed. Astronomers have long known that the Andromeda Galaxy, also called Messier 31, is a swirling city-state with a trillion stars – and all the precautions of gas, dust, dark matter, and black holes. Rumbles through the cosmos at a speed of 68 miles per second towards us. Five years ago, astronomers using the Hubble Space …
