The Milky Way, which contains our own solar system and many other stars and planets, is being actively pulled, twisted and distorted by the gravitational force of small galaxies, new research has found.
This large galaxy, named the Large Magellanic Cloud (LMC), is the second or third closest galaxy to the Milky Way. Visible as a faint cloud in the Southern Hemisphere’s night skies, it was also seen by its name: the Portuguese explorer Ferdinand Magellan. After inspecting the LMC during his travels in 1519, his later writings brought him into the general knowledge of Western society.
Scientists now believe that this neighboring galaxy penetrated the seam of the galaxy about 100,000 million years ago – most recently by the standards of the universe – and that its massive dark matter gained momentum with the fall of our galaxy’s fabric and motion.
Previous research has indicated that both the Milky Way and the LMC are surrounded by such large traps of dark matter, which can be described as elusive particles around Gauchars and do not absorb or emit light, but have a dramatic gravitational effect on the motion of stars and gases in the universe.
Using a state-of-the-art statistical model Dell that calculated the motion of the farthest stars in the Milky Way, researchers at the University of Edinburgh discovered how LMC was able to wrap up the motion of our galaxy. They observed that the dark matter halo of the LMC was moving the Milky Way galaxy 32 cm towards the constellation P. Gassus (a constellation in our northern sky). Pulling and turning at a speed of per second.
Surprisingly, the research team also found that, despite being attracted by the LMC, the galaxy is not moving toward the LMC’s current location (previously thought), but toward a point in its past path. This is because the LMC, powered by its tremendous gravitational force, is 370 km from the Milky Way. Moving at a faster speed per second. Scientists describe the movement of the galaxy Our galaxy is trying to hit a fast moving target, but the target is not very well aimed.
Speaking about the findings, George Perubia, personal chair professor of Gravitational Dynamics at the School of Physics and Astronomy, said: Understanding this can give us an unparalleled view of the distribution of dark matter in both galaxies. “
This discovery will help scientists develop new manipulative techniques that capture the strong dynamic interplay between two galaxies. Moreover, astronomers also intend to make an accurate study when LMC first arrived in the galaxy, as it will reveal the amount and distribution of dark matter in two galaxies with unprecedented detail.
The study and its findings were recently published in the journal Nature astronomy And here can be accessed.
