Deep Sky
M53

Constellation Coma Berenices
Globular Cluster
Apparent Magnitude 8.33

This beauty was discovered by Johann Bode in 1775, it is approx 60,000 light years away from the Galactic Center of the Milky Way. It is also approx 58,000 light-years from us.  It is one of the most distant globulars we have.  What’s also interesting about this globular is that it is well outside of our Milky Way, but the several hundred thousand stars are bound to our galaxy and to orbit for eternity. 

Most stars are so far from each other there is little chance of them colliding, however, globular clusters, especially one like M53, the stars are packed in much tighter and as a result they can and o collide.  If they do, they become blue stragglers, (cool name, huh).  Over 200 blue stragglers have been found in M53 alone.  Living in a neighborhood approx 12 billion years old, these blue stragglers will live fast and die young!
