[Curiosities] The Webb telescope captures a "green monster" inside a young supernova

[Mr.Hacker]

(CNN) -- The James Webb Space Telescope has captured never-before-seen colorful detail in one of the best-observed remnants of an exploded star. The glowing gas and dust of Cassiopeia A is all that remains of a star that exploded in a supernova and whose light first reached Earth 340 years ago. It is the youngest known supernova remnant in our galaxy, which is why the celestial object has been studied by a multitude of terrestrial and space telescopes. Cassiopeia A lies 11,000 light-years away, in the constellation Cassiopeia, and the remnant extends for 10 light-years.

 

 

A bright green loop along the right side of the bubble has also caught the interest of researchers. "We named it the Green Monster after Fenway Park in Boston. If you look closely, you can see that it's dotted with what look like mini bubbles," Milisavljevic explains. "Its shape and complexity are unexpected and difficult to understand." The team is still trying to understand the sources of the different colors in the image. Studying supernova remnants like Cas A can help scientists understand cosmic dust, a building block of stars and planets, and how exploding stars release crucial elements for life.
