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

Hubble snapped a new image of a glittering star cluster. Astronomers used a wide-angle camera

Wide Field Camera 3.This space object is also known as ESO 520-21 or Palomar 6. It 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 plates of the Palomar Observatory of the National Geographic Society.

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, they appear redder than they actually are. Astronomers refer to this process as “reddening,” and it makes determining the properties of globular clusters near the galactic center, such as ESO 520-21, especially difficult.
