The powerful space telescope captured a stunning image of the Cas A supernova remnant.
A new image from the James Webb Space Telescope shows in stunning detail the wreckage of a cataclysmic supernova explosion. remnant, known as Cassiopeia A , formed about 340 years ago from our perspective here on Earth. This makes the 10-light-year-wide Cas A one of the youngest clouds of supernova wreckage we know of. With images like this, scientists can perform"cosmic forensics" to better understand what happens when stars die.
and paved the way for living things, supplying elements like the calcium in our bones and the iron in our blood.Cassiopeia A is a supernova remnant located about 11,000 light-years from Earth in the constellation Cassiopeia. It spans approximately 10 light-years. This new image uses data from the James Webb Space Telescope's Mid-Infrared Instrument to reveal Cas A in a new light.
observes in — to the vibrant colors seen in the new image isn’t a purely aesthetic choice. It also reveals a wealth of scientific information that researchers are only just beginning to access. At the top of the newly released JWST image, and at the outer edge of a bubble of material blown out by the supernova, veils of orange and red represent emissions from warm dust, NASA officials said.
