What is this: Supernova residue Cassiopia near intersteller medium
Where is this: About 11,000 light-year away in Nakshatra Cassiopia,

Why is this so special: it Set of stunning paintings From James Web Space Telescope After more than 350 years, its intense light has long exposed the complex layers of glowing material around the dead star.
These paintings reveal an attractive phenomenon known as a light resonance – unconscious reflections of light emitted during a supernova explosion. When a star reaches and explodes to the end of his lifetime, it emits acute radiation that brings the surrounding gas and dust, produces a “echo” that can be seen in visual wavelength Is. Sometimes energetic supernova radiation also heats the dust of the nearby gas and intersteler medium, which emits its brightness, resulting in a rare type of mild echoing. Infrared Wavelength – The kind of light that excel in JWST spotting. According to NASA, infrared light eco in these images actually comes from the material behind Cassiopia A, not from the expelled material during the explosion.

The images are tightly packed, performing the nature -like nature of the intersteler medium, which looks a bit like an onion layers. These filamentary structures were seen in unprecedented detail, with the measurement taken on the scales of about 400 astronomical units (AU), which is 400 times from the average distance between the Earth and The SunFirst, astronomers have Identified The intersteter medium on the scales of Parasake has structures (1 parasek approximately 206,000 AUs, or 3.2 light-year). To find out that these structures exist on very small paraimans were new to researchers.
These magnificent curtains come from the observation of the same patches of dust taken on three different days-August 19, September 16, and 30 September, 2024-using camera near JWST. Three times, once combined, explains how a light resonance changes over time. (In the above images, the viewing area in the top row is slightly covered with the middle and bottom rows due to the tilt of the binoculars while taking those comments while taking those comments.)
Astronomers plan to study the scene using the mid-end equipment of JWST, which expects to see the light eco change in weeks or months. This will help them identify changes in the structure of the dust patch and will help check whether the molecules or dust grains are destroyed in the process.
