While James Webb’s incredible images get all the attention, Hubble is still going strong even thirty years after it was launched into orbit. In fact, to demonstrate their power, NASA, along with ESA published new images of a group of starsAnd it’s an impressive sight.

Located in the constellation Sagittarius, a globular cluster known as NGC 6638. appears in all its glory in a new, almost magical way. To capture it, Hubble used its Wide Field Camera 3 and Advanced Camera for Surveys.

The Hubble launch revolutionized the scientific understanding of globular clusters. Before its existence, the dense atmosphere of the Earth made it extremely difficult to study these stellar formations. Prior to this, it was impossible to clearly distinguish individual stars in these celestial bodies using conventional ground-based telescopes. However, take this powerful artifact into space forever changed how we could learn the same things.

Thanks to Hubble, agencies such as NASA, ESA and CSA have been able to improve our understanding of globular star clusters. The telescope for its more than thirty years of work has proven itself perfectly. Currently, James Webb comes in to take over and take space exploration to the next level. that until now we didn’t know what we could achieve.

What do we see in the picture taken by Hubble?

What does “globular cluster” mean? Well, it’s a set of stars arranged in a sphere., and which also revolve around the galactic core. Almost like a satellite.

All stars are strongly bound by gravity., a force that also organizes them in such a striking way. This, in turn, leads us to find higher density near its center and more diffuse order as we move away from it.

By studying these clusters, astronomers can study the development of stars in the universe, how they develop, and how important gravity is in their formation. Now James Webb He made a significant technical leap. With your cameras you will be able to observe infrared wavelengths.. This allows for a much clearer view of celestial bodies, given its lesser sensitivity to dust and gas obscuring formations.

In the case of NGC 6638, located in Sagittarius, has tens of billions of stars. An impressive amount that reminds us how small we are in the face of the vast cosmos.
