Globular Cluster Palomar 2
The globular cluster Palomar 2 was discovered in the 1950s by the American astronomer Albert George Wilson in the Palomar Observatory Sky Survey photo plates. George O. Abell published a list of 13 globular clusters and 73 planetary nebulae in 1955. He noted «highly obscured». 
Palomar 2 is a loose globular cluster of Shapley–Sawyer concentration class IX. The stars appear reddened due to the high absorption by interstellar gas due to the great distance. 
The globular cluster was studied in a study with the Hubble Space Telescope. The age has been estimated at 13.25 ± 0.12 billion years. It has about 140'000 solar masses. At a distance of 26.1 ± 1.5 kpc (about 85'000 light years) from the Sun, it is located in the outer halo of our Milky Way.
