Although the new James Webb Space Telescope has been capturing incredible images of celestial events, the Hubble Space Telescope has once again proved that, even though it may be old, it is still capable of capturing breathtaking images. Since the launch of Hubble in 1990, it has become relatively very easy to observe distant stars due to its presence about 340 miles above the Earth. Not just stars, but Hubble has also captured breathtaking images of groups of stars, known as Star Clusters.

NASA's Astronomy Picture of the Day is a breathtaking snapshot of the Globular Star Cluster NGC 6355, which is nearly 13 billion years old. Stars are celestial objects millions of years old floating in space. The older and bigger the star, the brighter it appears. They are formed in star-forming regions called Nebulae. The makeup of a Nebula consists of gases, mainly hydrogen and helium. After formation, many stars form groups from the same Nebula, which is known as a Star Cluster. According to NASA, Star clusters can contain as few as ten stars or as many as millions of stars.

The image was captured by the Hubble Space Telescope which is run by NASA and ESA in collaboration.

This stunning discovery by the Hubble Telescope further proves the capabilities of the Hubble Space Telescope.

Globular clusters once ruled the Milky Way. Back in the old days, back when our Galaxy first formed, perhaps thousands of globular clusters roamed our Galaxy. Today, there are less than 200 left. Over the eons, many globular clusters were destroyed by repeated fateful encounters with each other or the Galactic center. Surviving relics are older than any Earth fossil, older than any other structures in our Galaxy, and limit the universe itself in raw age.
