The Milky Way has been left disturbed by a collision with another, smaller galaxy, scientists say.
Some 700 million years ago – relatively recent, by the standards of the universe – the Milky Way suffered a crash that has left a long-lasting mark on its shape, scientists say. The discovery changes our understanding of the evolution of our galaxy and its history, they claim.
For a long time, our Milky Way has been viewed as relatively static, or has fallen into an equilibrium. Instead, it is undergoing savage contortions because of a collision with a smaller galaxy known as the Large Magellanic Cloud, or LMC.
The effects of that cosmic crash are still visible today, the researchers say, in the way they upset the fabric of the galaxy itself.
