U.S. space agency (NASA) said on Thursday (5/31/2012) that the Milky Way galaxy will collide with the Andromeda galaxy 4 billion years.
This was revealed by the Hubble Space Telescope observations. Andromeda is currently heading towards the Milky Way.
Commenting on the collision, Roeland van der Marel of the Space Telescope Science Institute in Baltimore, told the AP on Thursday (5/31/2012), said, “It’s like a poor car that crashed into the yard of the galaxy.”
Galaxy collision is a true merger of galaxies. When the collision, the speed of Andromeda is 1.92 million km per hour. Although quite so fast, the merger process will take 2 billion years.
Is this collision will destroy the Earth and the Sun in the Milky Way and the end result?
Scientists say, although the collision, the Earth and the Sun will be saved. There is a void space in the galaxy to help save the Earth and the Sun.
However, the collision will change a few things, among them a view of Earth’s night sky. The night sky will be dominated by the views of Andromeda. The nickname for the galaxy merger results have been prepared, namely Milkomeda.
The results of studies that Andromeda and the Milky Way will collide in four billion years to strengthen the previous studies conducted Avi Loeb, an astronomer at Harvard University.
Say, the less likely it did not hit a fumble Andromeda Milky Way. Collision would occur if the Andromeda moves to the side with speed 6 times faster than predicted.
Because the Milky Way and Andromeda similarly sized and equally 10 billion years old, it is difficult to predict which galaxies will suffer “collateral damage” losses due to collisions.
Scientists predict, when two galaxies merge has completed 4 billion years, the Sun still have 2 billion years before death.
The sun will become a red giant star, is likely to swallow the planet like Mercury, Venus, and Earth. Life on Earth is difficult to survive.
So, if the apocalypse is going to happen, instead of the Milky Way and Andromeda due to collisions, but most likely due to the Sun which will be dead.
