See the cluster of stars at the heart of the Milky Way. Usually it is impossible to see him

Hubble has taken a new picture of a sparkling star cluster. Astronomers used a wide-angle camera

Wide Field Camera 3.This space object is also known as ESO 520-21 or Palomar6. This is a globular cluster in the constellation Ophiuchus, which belongs to the halo of the Milky Way galaxy. It was first discovered by Roberto J. Harrington and Fritz Zwicky on the sky survey plates of the National Geographic Society's Palomar Observatory.

Although the Palomar 6has been studied many times, some important parameters of this cluster, such as distance to it, age and metallicity, were estimated only very roughly until recently. The visibility makes it difficult to locate the cluster - near the center of the Milky Way, where gas and dust absorb starlight and make observation difficult.

Due to this process the color changesastronomical objects, for example, appear redder than they really are. Astronomers call this process “reddening,” and it makes determining the properties of globular clusters near the galactic center, such as ESO 520-21, especially difficult.
