This is timeline of the Messier 87 galaxy, the Messier 87 galaxy is an elliptical galaxy in the constellation Virgo, located at 55 million light years away from earth
at 12.6 billion years ago, the Messier 87 galaxy was formed, when the Messier 87 galaxy was formed, It's was an starburst galaxy rather an elliptical galaxy, also, as the Messier 87 galaxy has merged with many other galaxy, the Messier 87 galaxy becomes an elliptical galaxy
hence this, we named galaxy that merged with the Messier 87 galaxy as Messier 87R, Messier 87S, Messier 87T, et cetera
Currently, the Messier 87 galaxy contains about 5 trillion stars, the age of most stars in the Messier 87 galaxy was more than twice of the sun
