New Delhi: NASA's Hubble space telescope has helped scientists reach out into the depths of the universe and discover numerous things that would have otherwise, been impossible.

With its hawk-like eye, Hubble, it can be said, has seen all and knows all, which has in turn, helped in making us familiar with our outer planetary world.

This time, Hubble has beamed back a stunning image of a globular star cluster, which is one of the most magical sights in the night sky.

These ornate spheres contain hundreds of thousands of stars, and reside in the outskirts of galaxies. The Milky Way contains over 150 such clusters.

As per NASA, as stars make their way through life they fuse elements together in their cores, creating heavier and heavier elements — known in astronomy as metals — in the process. When these stars die, they flood their surroundings with the material they have formed during their lifetimes, enriching the interstellar medium with metals. Stars that form later therefore contain higher proportions of metals than their older relatives.

By studying the different elements present within individual stars in NGC 362, astronomers discovered that the cluster boasts a surprisingly high metal content, indicating that it is younger than expected. Although most globular clusters are much older than the majority of stars in their host galaxy, NGC 362 bucks the trend, with an age lying between 10 and 11 billion years old. For reference, the age of the Milky Way is estimated to be above 13 billion years, NASA reported.
