You might have heard about the future collision of our neighbor Andromeda with our galaxy, the Milky Way. But hey, do you know its not the only galaxy heading towards collision with the Milky way.
M 90 or Messier 90 is one of such galaxies heading towards collision with Milky Way. This spiral galaxy is located around 60 million light years in the constellation Virgo. Even though both M 90 and Andromeda belongs to different galaxy clusters- Andromeda in Local Group and M 90 in Virgo cluster, both are destined to collide with the Milky Way. Our Universe is expanding and so galaxies are getting away from us. We know this by understanding the Doppler shift of the light coming from the galaxies. If the light is red shifted, then galaxies are getting away from us but if the light is blue shifted, then they are coming towards Milky way.
In case of M 90, the light is blue shift which means a future collision between M 90 and Milky Way or I say Milkomeda because by that time, Andromeda would have already collided with the Milky Way. The best time to view this galaxy is May. You can use Binoculars to view this galaxy in a dark, clean night sky.
