#CassiopeiaA is a #Supernova remnant located about 11,000 light-years from Earth in the constellation Cassiopeia.

It is the remnant of a massive star that exploded approximately 340 years ago as seen from Earth, and it is the brightest extrasolar radio source in the sky at frequencies above 1 GHz.

#PhotoOfTheDay: Adding Dimension to #CassiopeiaA

Using NASA’s James Webb Space Telescope, astronomers uncovered a mysterious feature within the supernova remnant Cassiopeia A , nicknamed the “Green Monster,” alongside a puzzling network of ejecta filaments forming a web of oxygen-rich material.

The James Webb Space Telescope has captured a stunning new image of an exploded star, or supernova remnant, in the constellation Cassiopeia. The image reveals the intricate details of the expanding gas and dust ejected from the star when it died. The supernova remnant, called Cassiopeia A, is a cosmic laboratory for studying the elements' origin and stars' evolution.
