Another Galaxy is on a Collision Course With the Milky Way

The Milky Way will collide with its neighboring galaxy, Andromeda, around 4 billion years ago.

This merger will dramatically change the two galaxies. But the researchers think that before

that there will be another merger with the Great Magellanic Cloud, the satellite galaxy of our

galaxy.

The Great Magellanic Cloud (LMC) is one of the largest and closest to the dwarf galaxies 

surrounding the Milky Way. It is located 163,000 light years away and entered our

neighborhood 1.5 billion years ago. People thought for a long time that it would either

continue to orbit our galaxy or it could even escape gravity, as it moves very fast. But recently

we discovered that it has a lot more dark matter than expected and its fate has changed

dramatically.

It is now expected that in about 2.4 billion years, it will reach the Milky Way. It will not

completely devastate the galaxy, but it will make substantial changes. Scientists expect

Sagittarius A *, the supermassive black hole at the center of the Milky Way, to receive an

influx of intense material. This will increase your mass significantly.

The obvious question is: will it affect the solar system?


"There is a small chance that we will not escape unscathed from the collision between the two

galaxies, which could get us out of the Milky Way and into aimless space," said Marius

Cautun of Durham University. The team of scientists think the scenario is unlikely, as only a

few of the stars located in the region where the Sun is at risk of collision with each other.

Anyway, by now our Sun will be increasing in size and getting closer to Earth, after all, we know that when its fuel runs out, it will gradually swell until it swallows the planets of the inner solar system. We don't need to heat our heads with this for now. [ IFLS ]
