Cape Canaveral, Florida – It turns out that an imminent collision between our Milky Way and Andromeda galaxy will not happen after all.
Astronomers reported on Monday that the two spiral galaxies were less likely to collide than previously thought, with a 50-50 chance over the next 10 billion years. Essentially, it’s a flip of the coin, but better than previous estimates and further time.
“For now, the declaration of our galaxy’s impending demise seems to be exaggerated,” a Finnish-led team wrote in a study that emerged in natural astronomy.
While the good news for the Milky Way is that the latest predictions of humanity may be a debate about humanity.
“We may not live to see the benefits,” Sawala of the University of Helsinki said in an email.
The Sun has been over 4.5 billion years old and can run out of energy and die within 5 billion years, but before it becomes so big, it will devour Mercury, Venus and possibly Earth. Even if it does not swallow the earth, the home planet will be left with a burning ball, and its ocean will be boiling.
Sawala’s international team relies on NASA’s Hubble Space Telescope and European Space Agency’s Gaia Star to measure the latest observations of the spacecraft to simulate possible scenarios of the Milky Way and neighbors next door. Both have collided with other ancient galaxies, and according to many, it seems destined to be a head-on crash.
Past theories collided between the two – leading to a new elliptical galaxy called Milkomeda – which might be possible if it is inevitable. In 5 billion years, some predictions will happen, if not soon.
In the new study, scientists rely on updated galaxy measurements to consider the gravity of the Milky Way’s motion through the universe. They found that the effects of adjacent triangular galaxies increased the likelihood of mergers between the Milky Way and Andromeda, while the large Magellan cloud reduced these opportunities.
Although uncertainty about the location, motion and mass of all these galaxies continues to be uncertain, scientists end up suffering from 50-50 collisions over the next 10 billion years.
“The fate of our galaxy is not only an astronomer, but not an astronomer,” said Raja Guhathakurta of the University of California, Santa Cruz.
He noted that a full-scale collision would transform our home galaxy from a pile of discs into a pile of stars scattered with milky light into milky spots. The harmless flight of two galaxies may cause this star disk to be largely disturbed, thus retaining our galaxy name.
Researchers say more work is needed before the fate of the Milky Way can be accurately predicted. Further insights should help scientists better understand what is happening in the deeper universe in galaxies.
Sawala said that while the fate of our galaxy is still highly uncertain, the future of the sun is “almost sealed.” “Of course, before that, humans also have a great chance to end themselves without the help of astrophysical.”
