This is in the direction of “Sagittarius”Globular Cluster “NGC 6638”This image captures the center of the . A globular cluster is a celestial body in which tens of thousands to millions of stars are gathered in a spherical shape. About 150 globular clusters have been discovered so far in the Milky Way galaxy.
This image of NGC 6638 is“Hubble” Space Telescopewas taken using According to the European Space Agency (ESA), which released the images, it was nearly impossible to clearly distinguish the individual stars that make up the globular cluster using ground-based telescopes that look through the Earth’s atmosphere. The appearance of the Hubble Space Telescope launched in April 1990revolution in astronomyIt has been used to study what stars make up globular clusters, how they evolve, and the role of gravity in dense star clusters.
and now“James Webb” Space Telescopeis about to revolutionize astronomy again.Specializing in infrared observationsThe Webb Space Telescope will be able to observe dust-obscured objects that are difficult to see in visible light, such as newborn stars surrounded by gas and dust. Observing newly formed star clusters made up of pre-evolutionary stars with the Webb Space Telescope is expected to further deepen our understanding of globular clusters.
The image above is from the Hubble Space Telescope.“Advanced camera for comet hunting observation (ACS)”and“Wide field camera 3 (WFC3)”It was created based on the image acquired using , and is released by ESA on August 1, 2022 as one of the Hubble Space Telescope’s images of the week.
