(ORDO NEWS) — This image taken by the Hubble Space Telescope shows the brilliant globular cluster NGC 6569 in the constellation Sagittarius.
Hubble explored the heart of this cluster with the Wide Field Camera 3 and the Advanced Observation Camera, finding a brilliant cluster of stars in this astronomical treasure trove.
Globular clusters are stable, closely associated clusters containing tens of thousands to millions of stars and associated with all types of galaxies.
The intense gravitational pull of these closely packed clusters of stars means that globular clusters are regularly spherical with a densely populated center, as seen in the center of this star-studded image.
This observation was obtained during the study of globular clusters located near the center of the Milky Way.
Previous studies have bypassed these objects because the dusty center of our galaxy blocks their light and changes the color of the stars in them.
The color of a star is especially important to astronomers studying stellar evolution and can give astronomers an idea of their age, composition, and temperature.
The astronomers who proposed these observations combined Hubble data with data from astronomical archives, allowing them to measure the age of globular clusters, including NGC 6569.
Their study also provided insight into the structure and density of globular clusters towards the center of the Milky Way.
