Inside galaxies, stars aren’t evenly spaced out. As a substitute, stars are likely to cluster into teams which might be as many as tens of 1000’s and even thousands and thousands of stars sturdy. These teams of stars, referred to as globular clusters, are tightly certain collectively by gravity and type a spherical form with a dense core of stars within the heart. They’re additionally visually gorgeous, with 1000’s of factors of sunshine seen in numerous colours representing stars of all completely different ages.
The picture of the week shared by scientists working with the Hubble Area Telescope this week reveals one such globular cluster named NGC 6355. Situated inside our personal galaxy, the Milky Means, this cluster is comparatively close by at lower than 50,000 light-years distance from Earth within the constellation of Ophiuchus.

The picture was captured utilizing Hubble’s Superior Digital camera for Surveys and Vast Subject Digital camera 3 devices, which may see the big construction in nice element. It’s tough to check globular clusters utilizing ground-based telescopes as water vapor within the Earth’s ambiance distorts the readings, making it tougher to resolve particular person stars inside the cluster. As Hubble is in area, orbiting across the Earth above its ambiance, it sits above this water vapor and so is ready to take extra detailed photos.
“The dense, brilliant core of NGC 6355 shines in crystal-clear element as Hubble is ready to resolve particular person stars within the crowded space towards the middle of this picture,” Hubble scientists write. “Hubble’s distinctive capabilities and vantage level above Earth’s light-distorting ambiance enable it to seize a globular cluster’s constituent stars intimately.”
