Despite the fact that the brand-new James Webb Space Telescope has recently taken some incredible images of celestial events, the Hubble Space Telescope continues to impress with its ability to take magnificent images.
The discovery of a galactic globular cluster in the interior of our Milky Way galaxy adds to the telescope’s list of accomplishments. This star cluster, designated NGC 6355, is located approximately 50,000 light-years away from Earth in the constellation Ophiuchus.
The Hubble Space Telescope image shows the dispersed stars of the globular cluster NGC 6355. NGC 6355 is a galactic globular cluster found in the centre of our Milky Way galaxy. It is less than 50,000 light-years away from Earth in the constellation Ophiuchus.
Globular clusters, which can contain tens of thousands to millions of stars, are stable, tightly bound groups that are linked to galaxies of all types. Because of their dense populations of stars and mutual gravitational attraction, these clusters have a roughly spherical shape with a bright, central concentration of stars surrounded by an increasingly sparse sprinkling of stars. The dense, bright core of NGC 6355 shines in stunning detail in the crowded region toward the centre of this image, which is too crowded for Hubble to resolve individual stars.
Hubble has transformed the way globular clusters are studied. Individual stars in globular clusters are nearly impossible to distinguish with ground-based telescopes. Because of its unique capabilities and elevated position above the Earth’s light-distorting atmosphere, Hubble is able to capture the individual stars that comprise a globular cluster in great detail. This image includes data from Hubble‘s Wide Field Camera 3 and Advanced Camera for Surveys.
