More than a decade ago, scientists predicted Our Milky Travel Galaxy and Andromeda Neighborhood would be crashed In four billion years, resulting in “Makeor” with our solar system.
This is unlikely – at least within the expected time frame.
“We see out the external galaxies that often collide and connect with other galaxies, sometimes producing the equivalent fireworks when gasoline, flip the central hole,” Durham University professor Carlos Frank explained.
“So far, we thought it was the fate expected Our Milky Way Galaxy,“Ua said statement. “Now we know that there is a very good chance that we may avoid that terrible destiny.”
Previous research from the Astronomer NASA They found that the collision with our closest neighbor Galaxy will throw the sun on the new region of space, although the country would not be destroyed. The stars would be sent to different orbits. Currently, the galaxies move each other at approximately 62 miles per second.
But after 100,000 simulations and galaxies based on the latest observational data from the Hubble and European Space Agency Gaia Space Telescopes, the authors of the study published in the journal Nature Astronomy They found only 2 percent probability that the Milky Way and Andromeda will crash against each other over the next five billion years.
In more than half of the scenario, the galaxies experienced at least one close encounter before they lost enough orbital energy to collide and merge. However, that would happen in about eight to 10 billion years. Until then, The sun might have burned When he runs out of hydrogen, I consume the country.
But, in most other cases, galaxies passes each other without an incident, although there is space for insecurity.
Furthermore, the authors claim that previous research was not incorrect, but that they managed to include more variables in their simulations.
“While some earlier works focused on interaction between the Milky Way, Andromeda and Galaxy Triangulum,” said the leading author of Dr. to Sawal, Sawal, Sawala, Sawalau, Sawalau, Sawinki. The cloud is a galaxy dwarf that orbits the Milky Way. “Although her mass is only about 15 percent of the Milky Way, her gravity move is pointed vertically on orbit with Andromeda Forturbs Milky Way’s Motion enough to significantly reduce the possibility of merging with Galaxy Andromeda Galaxy.”
However, the authors already want to update their findings to new data. The European Space Space Telescope in the closed agency will soon provide more precise measurements of key factors within the galaxy, including Andromeda. Nevertheless, Frank said that the results of the “testimony” of the power of great supercompos.
“When I See The Results of Our Calculations, I am Astonished That We Are Able to Simulate With Such Precision The Evolution of Gigantic Collections of Stars Over Billions Of Years And Figure Out Their Ultimate Fate,” He Added.
