The iconic Hubble Space Telescope has captured a glimmering new photo of a densely packed region of stars located in the constellation Sagittarius. .

The grouping of stars is a globular cluster known as NGC 6558, which lies 23,000 light-years from Earth.

The new photo was taken by the Hubble Space Telescope's Advanced Camera for Surveys, which is designed to survey large areas of the sky at visible and red wavelengths.

"As this observation shows, the stars in globular clusters can be densely packed; this image is thronged with stars in a rich variety of hues.".

The globular cluster features bright stars, some of which are surrounded by prominent diffraction spikes, or lines radiating from bright light sources.

"Globular clusters equip astronomers with interesting natural laboratories in which to test their theories, as all the stars in a globular cluster formed at approximately the same time with similar initial composition," ESA representatives said in the statement.

The recent Hubble image was taken as part of a project to study globular clusters in the inner Milky Way, which may offer new clues into how such stellar groupings form and evolve. .
