(ORDO NEWS) — Scientists conducted a new study in which they tracked how thousands of galaxies move, as well as their clusters, located at a distance of 350 million years from our planet.
They also managed to create a visualization of how they moved over the past 11.5 billion years.
Astronomers have been able to calculate how galaxies have moved over billions of years. To do this, they used information regarding their brightness, position, and current movement.After the Big Bang happened, galaxies move very fast as our universe continues to expand.
Under the influence of gravity, the movement of galaxies gradually begins to change in such a way that they do not diverge in different directions, but, on the contrary, gather into huge clusters or filaments. At the same time, large voids remain in outer space, where galaxies are completely absent.
Ed Shaya, from the University of Maryland, spoke about how much attention was paid to how large-scale structures formed within the universe. They found several places where there are a huge number of galaxies.
At the same time, special attention of specialists was attracted by a gravitational anomaly, called the Great Attractor. It is located in the constellation Nagolon at a distance of about 250 million light-years from Earth.
The mass of the object is 100,000 times greater than the mass of the Milky Way. The Great Attractor acts as the core of the Laniakea supercluster of galaxies, in which our galaxy is also located. The cluster is 520 million light-years across and contains 100,000 galaxies of various sizes.
Another interesting region in the universe is the Perseus-Pegasus galactic filament. The length of the thread reaches a mark of a billion light years. It is she who is considered the largest space structure.
Thanks to the created visualization, specialists were able to follow the process of the divergence of galaxies in outer space and establish the paths of their movement until the moment when the Universe becomes almost twice as old.
Over the next 10 billion years, only a few major mergers of galaxies can occur in those regions where the highest density of matter is recorded.
