M15 – Great Pegasus Cluster
M15 is about 35,700 light-years from Earth and 175 light-years in diameter. Messier 15 is one of the most densely packed globulars known in the Milky Way galaxy. Home to over 100,000 stars, the cluster is notable for containing a large number of variable stars and pulsars, including one double neutron star system.

M13 -The Great Hercules Cluster
Messier 13, at the distance of 25.000 light-years from our Solar system, contains several hundred thousand stars; some sources even quote more than a million. In the photo you can also see NGC6207, a spiral galaxy some 50 million light-years from our solar system. And also IC4617, a spiral galaxy some 536 million light-years from our solar system, twice as large as NGC6207 and about 700 times larger than M13.
M53 & NGC5053
Globular clusters in the constellation Coma Berenices. Each one of the two clusters contains around 500.000 stars.
Imagine a million suns with possible planet systems around many, if not all, of them…
