Milky Way’s chance of colliding with galaxy billions of years from now? New study puts odds at 50-50
Cape Canaveral, FLA. (AP) – It turns out that the collision that is looming on the horizon between us milky way And Andromeda galaxies may not happen after all.
Astrologists reported that the possibility of the two Sealing galaxies The collision is less than it was previously thought, with a chance of 50-50 in the next 10 billion years. This is mainly a coin, but there are still better possibilities than previous estimates and time exit.
As is the case, the disappearance of Washik Our galaxy The team -led team wrote in a study that appears in natural astronomy.
Although the good news of the Milky Way, the latest expectations may be a discussion of humanity.
“We will not live to see the benefit,” the main author said even a question from Helsinki University in an email.
Indeed, more than 4.5 billion years, the sun is on its way to running energy and die in another 5 billion years or so, but not before it becomes very large so that it swallows mercury, flower and possibly the ground. Even if the Earth does not swallow, the home planet will be left a burning ball, and its surroundings have long been left.
The Sawala International team relied on the latest notes by Tilescope Hubble Space Telescope, NASA, and the Gaia Strevertate Award in NASA and the European Space Agency in its neighbor in my neighbor, Wagromeda, adjacent Andromeda. Both of them actually collided with other galaxies in their old past, and according to many, he seemed destined to destroy them.
Previous theories laid down a collision between the two – which led to a new oval galaxy called Milkomeda – as possible if not inevitable. Some predictions occurred within 5 billion years, if not sooner.
For this new study, scientists relied on the updated galaxy measurements of its worker to withdraw gravity on the movement of the Milky Way through the universe. They found that the effects of the neighboring triangle galaxy increased the possibility of integration between the Milky Way and Andromida, while the large majestic cloud reduced these opportunities.
Despite the constant uncertainty of this situation, the movement and mass of all these galaxies, the scientists ended 50-50 of collision during the next 10 billion years.
“The fate of the Milky Way is an important topic – not only for astronomers,” said Raja Ghattakorta of the University of California, Santa Cruz, who did not participate in the study.
He pointed out that the complete collision will turn our home galaxy from a tablet of stars that are seen as a milky band of light spread across the sky into a milky point. A harmless fly can leave this star disk greatly without disturbing, thus maintaining the name of our galaxy.
More work is needed before predicting the fate of the Milky Way, according to researchers. More insight should help scientists understand what is happening between galaxies better even deeper in the universe.
While our Galaxy’s fate is still largely inconsistent, the future of the sun is “largely closed”, according to Saal. “Of course, there is also a very big opportunity because humanity will put an end to itself before that, without any need to help astronomical physics.”
