Milky Way Versus Andromeda As Seen from Earth

Astronomers have used the Hubble Space Telescopeto forecast a future cosmic pile up: the titanic collision of the Milky Way and the Andromedagalaxy in about four billion years time. The Andromeda Galaxy, some 2.2 million lightyearsaway, is the closest spiral galaxy to our home, the Milky Way. For around a century,astronomers have known it is moving towards us, but whether or not the two galaxies wouldactually collide, or simply fly past each other, remained unclear. Now, a team of astronomershas used the Hubble Space Telescope to shed light on this question, by looking at themotion stars in the Andromeda Galaxy. We wanted to figure out how Andromeda wasmoving through space. So in order to do that

we measured the location of the Andromedastars relative to the background galaxies. In 2002 they were in one place, and in 2010they were in a slightly different place. And that allowed us to measure the motion overa period of eight years. The motion is actually incredibly subtle,and not obvious to the human eye, even when looking at Hubble's sharp images. However,sophisticated image analysis revealed tiny movements that the scientists were able toproject into the future. Based on these findings, it is finally possibleto show what will happen to the Milky Way over the next eight billion years, as thegalaxies drift closer, then collide and gradually

merge into a single, larger, elliptical galaxywith reddish stars. And yet the Solar System should in fact survive this huge crash. The reason we think that our Solar Systemwill not be much affected by this collision between the Milky Way and Andromeda is thatgalaxies are mostly empty space. Even though our galaxy, as well as the AndromedaGalaxy, has a hundred billion stars in it, they are very far apart. So if two galaxiesactually collide with each other, the stars basically pass right between each other andthe chance of two stars directly hitting each other is really, really small. So the likelihoodthat our Solar System will be directly impacted

by another star, for example, in Andromedaas we collide with it is really, really small. Well, if life is still present on Earth whenthis happens, the changes in the sky will be quite spectacular. Now they will be veryvery slow because the timescales on the scales of galaxies in the Universe are very verylong. So you have to think, millions of years but even then over these timescales over millionsof years, we will see big changes. If we wait a few billion years, Andromeda will be hugeon the sky. It will be as big as our Milky Way because we'll be very close to it. And then later, when the galaxies merge, themerged remnant of the Milky Way Galaxy and

Andromeda will look more like an ellipticalgalaxy and we'll be sitting right in it. So the view of the Milky Way on the nightsky will be completely gone and this band of light will be replaced by a more spheroidaldistribution of light. And so, the Sun, born in the Milky Way almost5 billion years ago will end its life in a new orbit, as part of a new galaxy.
