The disaster between our galaxy galaxy and its neighbor, Andromeda, will take around 4.5 billion years after delaying about 600 million years.
"The apocalypse was suspended," said New York Times (NYT) as he said Tuesday. Unlike the situation in which two diseases are headaches, they are expected to be tied together as if they were removed.
Researchers at the United States Spanish Scientific Sciences Research Institute (STScl) Rollund van der Marell made this decision based on the views of the galaxy and galaxy triangular Andromeda released by satellite GIA of the European Association of Europe (ESA) in April last year. The results are published in the current journal of the Astrophysical Journal magazine.
The Andromeda galaxy (M31) and a triangular galaxy (M33) are related to the same local galaxy as a galaxy and are called galax alongside. It is a group of galaxies in which there is a galaxy in the local disease, with about 30 galaxies, and including alone. Searchers believe that the M31 and M33 are far apart with 2.5 million years of light and 3 million light years, individually, in our galaxy. In particular, aircrafts have been using Teleascop Space Hubble for five years ago, and the M31 has been in & # 39; Just go to our disease at a distance of around 109km each second and they were think the accident was ahead after around 3.9 billion years.
But, as ESA launches Gaia satellite in 2013, it will be able to predict more precisely the disease disasters; already. Gaia launched in December 2013 a correct analysis of the situation, trendy and clear of about 1.3 billion star in our galaxy, and finished a 3D space map last May.
"The Gaia has already been built to map our galaxy, but the satellite performance is longer than expected," said Timothy Prusutia, a researcher at the Gaia project. "Gaia satellites gave small movements of several galaxies. The more detailed the dimensions."
The survey showed that the M31 does not go directly to our galaxy, but it's a? move in a broken form. The speed was also 32km / lane, slower than expected. Dr. van der Marel, who researched, "According to this inspection (M31 and we do), it will be a bit of a bit about 400,000 years ago," he said. "In the end, it is likely that it will be introduced into the swimmers. The accident has been delayed from 3.9 billion years to 4.5 billion years since now.
The researchers also confirmed that the M33 can not have the idea; Now the M31 is moving around to & # 39; His 6 billion year cycle, and concluded that the M33 was destroyed to the M31.
"He gave us 100 years to reach this decision by precisely measuring the momentum momentum of the M31, the galaxy closest to our galaxy," said Gaia. "This will help us to understand the nature of our disease," he said.
The researchers believe that there is little likelihood of our solar system in relation to two diseases. In fact, the distances between the stars and stars in the batteries are very small and are not very tight.
On the other hand, Galaxy will have to make any extra strides before we meet M31. It's because the Galaxy-Magellanic Galaxy (LMC) satellite is a & # 39; come to our disease as a course; war. The astrophysical research team of Durham Research vs Cosmetology Computational (ICC) can see the time to be & # 39; war around two billion years.
