Today’s Image of the Day from the European Space Agency features one of the most well-known open star clusters known as Messier 11.
The cluster contains thousands of stars, many of which are hot and young blue stars in the center.
Messier 11 is also known as the Wild Duck Cluster because its brightest stars form a “V” shape that resembles a flying formation of ducks.
Astronomers estimate that Messier 11 formed around 220 million years ago.
