After NASA’s newest James Webb space telescope was activated, it has been taking pictures of previously unseen stars. Recently, NASA released new photos The bright stars are a “super star cluster” called Westerlund 1, which is very rare.
According to NASA, the Milky Way produced more star clusters billions of years ago, but now new stars don’t appear often anymore, and only a few super star clusters remain. Westerlund 1 is the largest supercluster in the Milky Way and the closest to Earth It is located 12,000 light-years away from Earth It consists of massive stars with a mass of 50,000 to 100,000 times that of the Sun , distributed in area 6 light. – years in diameter.
The stars in the image, taken using the space telescope’s Near Infrared Camera (NIRCam), include yellow supernovae, which are about 1 million times brighter than the Sun. Since the stars in the cluster have a relatively short lifespan, scientists believe that it is only about 3.5 million to 5 million years old, which is very young. NASA said the discovery could help better understand the formation and death of massive stars.
