A single still from a video of the Kepler Supernova Remnant is shown here using Chandra data taken in 2000, 2004, 2006, 2014, and 2025. When the data collected over the years is viewed as a timelapse, it makes it the longest-spanning video that Chandra has ever released. It also gives astronomers a remarkable view into the aftermath of a Type Ia supernova, a class of stellar explosion created from the thermonuclear detonation of a white dwarf star that scientists use to measure the expansion of the universe. The supernova was witnessed by German astronomer Johannes Kepler in 1604 A.D.

This artist’s concept depicts a smaller white dwarf star pulling material from a larger star, right, into an accretion disk. Earlier this year, scientists used NASA’s IXPE (Imaging X-ray Polarization Explorer) to study a white dwarf star and its X-ray polarization.
