NASA's Hubble Space Telescope captured a new image of globular cluster IC 4499. The image shows a diamond shaped cluster of stars, which is around 50,000 light years away from Earth and orbits in Milky Way galaxy.
Scientists claimed that the image will help them to find how old that globular cluster really is.
In the 1990s, scientists observed IC 4499 and found that the globular cluster is much younger than other globular clusters in the Milky Way. The recent image captured by Hubble can help scientists to confirm the age of IC 4499.
According to NASA's recent reports, while huge globular clusters consist of multiple generations of stars, the medium-sized globular clusters have only the stars born around the same time.
The globular cluster is a group of old stars that orbits around its galaxy. Before getting this image, scientists considered that all stars of globular clusters have same age. The image of globular star cluster IC 4499 shows that massive clusters have stars of different ages.
The image of IC 4499 shows that it probably has just a single generation of stars. Once astronomers thought that the stars in IC 4499 were young and larger clusters have stars as old as 12 billion years. The image from Hubble suggests that IC 4499 is as old as other clusters.
NASA had launched the Hubble Space Telescope in 1990, which is the only telescope made for servicing space by astronauts. Recently, it has discovered a zombie star and provided a better look at the planets present outside earth's solar system. Hubble has 8-foot mirror that can measure ultraviolet as well as infrared light. The telescope provides clear images as there is no background light to spread them.
