Our Milky Way: Double KO punch in two galactic collisions – astronomers



A research team from Britain's Durham University predicts that another galaxy will collide with the Milky Way much sooner than expected and launch our solar system into space.

"There is little chance that we will get away with it" The collision between the two galaxies that could throw us out of the Milky Way into interstellar space, "said Marius Cautun, a postdoctoral fellow at the Durham Institute for Computational Cosmology. in a recent statement received from Business Insiders.

Cautun is the lead author on a paper entitled "The Aftermath of the Great Collision Between Our Galaxy and the Large Magellanic Cloud," published in the September monthly bulletins of the Royal Astronomical Society

The collision between the Milky Way and the Large Magellanic Cloud (LMC), a Milky Way satellite galaxy, is expected to occur in 2 billion years.

But the crash would come much sooner than an impending collision between the Milky Way and the Andromeda Galaxy, which is expected to be in just 8 mill iarden years will take place, or more than half of the existence of the known universe.

"While 2 billion years are an extremely long time compared to a human life, this is a very short time on cosmic timescales," Cautun noted.

New research shows that the LMC has twice as much dark matter as before and the undiscovered mass could slow down the galaxy so much that it could not escape the attraction of the Milky Way's Milky Way.

Astronomers also believe that a collision will trigger the Milky Way's enormous dormant black hole, which then begins to feed near gas as it gets bigger.

"Apart from catastrophes, such as a major disruption of the solar system, our offspring, if any, are special: a spectacular spectacle of cosmic fireworks as the newly awakened super A massive black hole in the center of our galaxy responds by making rays extremely brighter emitted high-energy radiation, "noted study co-author Carlos Frenk, cited by Business Insider.

According to the researchers, however, a collision between the two galaxies is behind schedule.

Dr. Duris University Institute for Computational Cosmology's Alis Deason said, "We believe that our galaxy has so far had few fusions with very low mass galaxies," quoted by Physics.org.

. This compares very slender results to nearby galaxies of the same size as the Milky Way. For example, our nearest neighbor, the Andromeda galaxy, has devoured galaxies that weigh almost 30 times as much as the Milky Way. Therefore, the collision with the large Magellanic Cloud is long overdue and it is necessary to make our galaxy typical, "she added.
