No red carpet necessary for this star-studded event 🎊
A globular cluster is pictured here in the constellation Sagittarius, located near the center of the Milky Way. The NASAHubble Space Telescope captured this dazzling scene using its Wide Field Camera 3 and Advanced Camera for Surveys.
Globular clusters are made up of tightly bound groups of tens of thousands to millions of stars. This starry snapshot is set in our home galaxy, the Milky Way, in its central region which holds a tightly packed group of stars that are rich in interstellar dust. The dust makes the globular clusters near the galaxy’s center difficult to study, as it absorbs starlight and can even change the apparent color of stars in these clusters.
Hubble is a class act. Its sensitivities to both visible and infrared wavelengths allows astronomers to measure how star colors change due to interstellar dust. Knowing a star’s true color and brightness allows astronomers to estimate its age, and the age of its g...
