"We are literally mapping the entire celestial sky in 102 infrared colors for the first time in humanity's history." ...

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 ...

What’s more, Webb used its Near Infrared Camera (NIRCam) instrument to observe glowing interstellar gas and dust illuminated by a supernova explosion approximately 350 years ago. The material glows in ...

This wisp had been identified as a light echo by NASA's now-retired Spitzer space telescope. But Spitzer didn't have the resolution of JWST. Even so, "we were pretty shocked to see this level of ...

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.

Using NASA's space-based Chandra X-ray Observatory and the retired Spitzer Space Telescope, astronomers have discovered "danger zones" for planets that are forming around young stars. The team ...

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 ...

The Hubble is just one of NASA's orbiting "great observatories." The group also includes the Spitzer Space Telescope and the Chandra X-ray Observatory. Spitzer is an infrared orbiting telescope ...

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 ...

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 ...
