Here’s the background — Cassiopeia A exploded as a supernova about 11,000 years ago, and its light finally reached Earth around 1670, although the telescopes at the time weren’t powerful ...

A young NASA mission spotted strange movements of X-rays in the supernova remnant known as Cassiopeia A, which may include an extremely dense and small star.

That light, which we now know is from the supernova Cassiopeia A, has just been captured in never-before-seen detail by the Webb Space Telescope.

Researchers announced the latest findings from the James Webb Space Telescope (JWST) of the supernova remnant, Cassiopeia A (Cas A). These observations of the youngest known core collapse ...

Back to Article List View the Cassiopeia A supernova remnant in 3D Sophisticated computational models let us examine objects such as supernova remnants in extraordinary detail and from every angle.

The newest image of supernova remnant Cassiopeia A uses different colors to designate different wavelengths of energy. “With some clever manipulation of the filters, we are able to look closely at the ...

Astounding new Webb Space Telescope images of supernova remnant Cassiopeia A may finally help astronomers understand how supernovae generate life’s biomolecular precursors.

A new Webb image of Cassiopeia A captures the iconic supernova remnant in sparkling detail unlike we've ever captured.

A new study has described in detail a dying star initially recorded in 1181. The object may belong to a rare class of supernovas that leaves behind a “zombie star.” ...

New 3D-printable models of Chandra X-ray Observatory images will allow you to hold a star in your hands and touch a supernova remnant.

A new high-definition image from NASA’s James Webb Space Telescope’s NIRCam unveils intricate details of supernova remnant Cassiopeia A and shows the expanding shell of material slamming into ...
