#2023. W 26 D 3 GMT +08:00. Indicate #186 days to go in 2023. Thanks to James Webb Space Telescope, we see in the mid-infrared an object formed about 340 years ago due to a star explosion. The image’s orange areas are where the explosion’s ejected material collides with the surrounding gas and dust. Meantime the green loop is still a mystery to many scientists as the shape and complexity of the structure are very unexpected to understand. However, the light pink color is the mare of the star itself, which is illuminated by heavy elements such as Oxygen, Argon, and Neon. Those are the complex in the color of the star explosion that is a supernova remnant in the constellation Cassiopeia.
