Andromeda is approaching to Milky way galaxy at the speed of 110km/s (68mi/s) which is studied according to blue-shift. The sidelong speed is extremely hard to quantify with an accuracy to reach sensible inferences: a horizontal speed of just 7.7 km/s would imply that the Andromeda is advancing toward a point 177,800 light-years to the side of the Smooth Way ((7.7 km/s)/(110 km/s) × (2,540,000 ly)), and such a speed over an eight-year time span adds up to just 1/3,000th of a Hubble Space Telescope pixel (Hubble’s resolution≈0.05 arc-sec: (7.7 km/s)/(300,000 km/s)×(8 y)/(2,540,000 ly)×180°/π×3600 = 0.000017 arc-sec).
Until 2012, it was not known whether the conceivable impact was certainly going to occur or not. In 2012, specialists reasoned that the crash is certain utilizing Hubble to follow the movement of stars in Andromeda somewhere in the range of 2002 and 2010 with sub-pixel exactness.
So, according to calculation it would take 4 billions of years from now, our galaxy will collide to Andromeda
Collision between galaxies are common it is believed that Andromeda has collided with at least a galxy before.
What Will Happen After Collision ?
The galaxy we know wont survive for long.Truth be told, our nearby planetary group will outlast our universe. By then, the sun won’t yet be a red giant star – yet it will have become sufficiently brilliant to broil Earth’s surface. Any living things still there, however, will be blessed to receive some entirely tremendous astronomical movement.
At present, Andromeda and the Smooth Route are about 2.5 million light-years separated. Powered by gravity, the two systems are tearing toward each other at 402,000 kilometers for every hour. However, even at that speed, they won’t meet for another four billion years. At that point, the two cosmic systems will impact head-on and fly through each other, leaving gassy, starry ringlets in their wakes. For ages, the combine will keep on meeting up and fly separated, scrambling stars and redrawing heavenly bodies until in the long run.
Then After Solar System will have new cosmic location. This isn’t a part tore from sci-fi – it’s a genuine, logical forecast.That Newton could portray the circles of planets, and Halley the arrival of his eponymous comet, and contemporary stargazers, the finish of the Smooth Way – this endowment of foreknowledge is extremely a numerical comprehension of the physical laws that administer the developments of divine bodies.
Fortunately, a group of top researcher says, stars are so far separated that despite the fact that worlds are impacting, the probabilities of outstanding crashes are little. So the sun and its planets will probably endure the introduction of Milkomeda, however Earth will never again have the capacity to call the Smooth Way home. Also, we’ll never again live in a winding world: Milkomeda will be curved fit as a fiddle, and it’ll most likely look really red.
