Today NASA released a stunning photo of the center of globular cluster NGC 6362, made up of stars 10 billion years old. The photo shows a high concentration of stars with different colors, found 25,000 light-years from Earth.
Globular clusters are common but rarely photographed. More than 150 of these clusters are currently known in our galaxy, the Milky Way, NASA writes. Why are they worth researching?
"Globular clusters are among the oldest structures in the Universe that are accessible to direct observational investigation, making them living fossils from the early years of the cosmos," the release states. In fact, these clusters are older than the sun.
The photo shows NGC 6362, located approximately 25,000 light-years from Earth in the constellation of Ara (The Altar). This image was created combining ultraviolet, visual and infrared images taken with the Wide Field Channel of the Advanced Camera for Surveys and the Wide Field Camera 3, NASA explains.
