The website Chileno notes [en] that a Chilean-led team of astronomers has shed new light on the evolution of galaxies by observing young star formations in outer regions of the interacting galaxy NGC 92. As lead author Dr Sergio Torres from Universidad de La Serena explains, there is something special about interacting galaxies like NGC 92. They are as he says, “perfect laboratories to study galaxy evolution”:
The unassumingly titled NGC 92 galaxy isn’t a close one. On the contrary, it’s quite far away, 160 million light years away to be precise, or roughly 940 quintillion miles. That’s a lot of noughts.
