Composite images of the Cas A supernova remnant, a structure resulting from the explosion of a star in the Cassiopeia constellation. The blues represent data from the Chandra Observatory, the ...

Using cutting-edge theoretical models and data from NASA's Chandra X-ray Observatory, scientists have transformed astronomical observations into detailed 3D models of cosmic objects — models that ...

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 supernova in ...

Astronomers used data from multiple space telescopes to create 3D models of celestial objects. These models help scientists understand how stars explode and die (supernovae). The models show the ...

For the first time, scientists have made a clear X-ray detection of chlorine and potassium in the wreckage of a star using data from the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) ...
