"Astronomers Unravel 'Green Monster' Mystery in Supernova Remnant"

Astronomers have discovered that the "Green Monster," a peculiar green light seen in the remnants of a supernova explosion, is actually a blast wave bordering the debris field. The James Webb Space Telescope captured unprecedented detail of the supernova remnant, revealing a 10-light-year-long ball of light infused with red clouds and streaks of white, green, and orange light. The X-ray properties of the Green Monster match those of the outer regions of the supernova debris field, suggesting it was created when a blast wave collided with material shed by the star thousands of years before its explosion. Additionally, the study uncovered a network of "pristine debris" near the center of the explosion, shedding light on the physical processes involved in the star's collapse.
