Description of Pal 1
Discovered by George Abell in 1954. A team of astronomers lead by Alfred Rosenberg of Padova, Italy has closer investigated globular cluster Palomar 1. First, they confirm its nature as a globular by finding that its properties and location in the outer halo, about 55,000 light-years from the Galaxy's center, contradict the possibility of a very old open cluster. They find that Palomar 1 is probably younger than most globulars, and could have been created in a different formation process. Source: Seds.org \| Notify inaccuracies
