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 ...

Scientists targeted a light echo previously observed by NASA’s retired Spitzer Space Telescope, and it is one of dozens found near remains of the Cassiopeia A supernova. The Webb images show ...

The light echoes were first detected by NASA's retired Spitzer Space Telescope, but Webb's high-resolution imaging has provided clearer views of these cosmic phenomena. The echoes result from a ...

Sometimes, scientists get lucky: In 2012, NASA's Spitzer Space Telescope grabbed an image of lacy interstellar medium illuminated by Zeta Ophiuchi, a large star roughly 370 light-years away.

Jencson (Caltech/IPAC) The researchers targeted a light echo that had previously been observed by NASA's retired Spitzer Space Telescope. It is one of dozens of light echoes seen near the ...
