The recently observed glowing material, not related to the star that turned into Cassiopeia A, exists among dozens of other nearby light echoes that had first been observed by NASA's Spitzer Space ...

As light from the explosion, which we now call Cassiopeia A, expanded outwards, it reflected off and warmed the tenuous ...

A light echo is created when a star explodes or erupts, flashing light into surrounding clumps of dust and causing them to shine in an ever-expanding pattern.

In the constellation Cassiopeia, a supernova flash has acted as a cosmic spotlight, lighting up this interstellar material. NASA’s James Webb Space Telescope has revealed stunning new details, ...

The images also depict dense, tightly wrapped regions resembling wood grain knots. These may be magnetic “islands” among the more streamlined ... potentially revealing more infrared light echoes for ...
