It is noteworthy that Webb was not created to observe such events. Instead, the telescope is designed to study distant planets and detect signs of life.
In recent images from the James Webb Space Telescope, astronomers have noticed something unusual happening in the distant galaxy SDSS J141930.11+525159.3, writes BGR.
According to experts, this something is most likely a supernova. Moreover, as scientists note, this bright object is the first supernova discovered by the Webb telescope. The object is much brighter than the rest of the galaxy. And when Webb observed the galaxy 5 days apart, the object dimmed slightly. All this is consistent with the behavior of a supernova.
The new series of images taken by James Webb is not as striking as the previous images. However, they are still quite mesmerizing. The image is split into four fields, including two Webb images and one Hubble image. The fourth demonstrates the difference between the two telescopes. If you look closely, you can almost see a possible supernova.
Remarkably, James Webb was not created to observe such events. Instead, it is designed to study distant planets and detect signs of life. So the fact that it may have spotted a supernova is impressive.
The space telescope continues to exceed expectations despite minor damage. The galaxy in which Webb spotted the supernova is 3 to 4 billion light-years away. As a result, the difference we see is the slowly fading light of an explosion that occurred 3-4 billion years ago.
In fact, the death of a star takes a fraction of a second, but the resulting fireball grows and becomes brighter for several days, and then gradually disappears over the next few months. It's only a blink of an eye in astronomical terms, so Webb was able to detect this supernova shortly after it peaked.
