The space agency pieced together the evolution of Kepler’s Supernova Remnant from the data of NASA’s Chandra X-ray Observatory over 25 years.

NASA has released an unprecedented time-lapse video showing the evolution of Kepler’s Supernova Remnant, a cosmic relic of a massive stellar explosion. Captured by the Chandra X-ray Observatory over ...

The shockwave has traveled half a light-year.

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 ...

"Why are we here?" is humanity's most fundamental and persistent question. Tracing the origins of the elements is a direct attempt to answer this at its deepest level. We know many elements are ...

Decades in the making, NASA's X-ray timelapse shows a stellar explosion expanding into space at up to 2% the speed of light.

Supernova 1987A, the nearest observed supernova in modern history, continues to offer profound insights into the life‐cycle of massive stars. Its distinctive features, including a prominent equatorial ...

Italian astronomers have developed a 3-D model for the supernova remnant (SNR) IC 443 in order to investigate the morphology of this source. The model allowed the researchers to gain more insights ...

A star collapses when it dies, spewing space dust in a giant cloud of elements that make for very beautiful Hubble Telescope photos. The “explosion,” called a supernova, results in either a black hole ...

When a supernova was seen glittering in the night sky for six months in 1181, it was so bright that Chinese and Japanese astronomers recorded it as a “guest star” in the Cassiopeia constellation. Now, ...
