Scientists have Unveiled a Decades-Long Video of a Supernova Remnant Captured by NASA's Chandra X-ray Observatory
A remarkable video, spanning over 25 years, has been released by NASA's Chandra X-ray Observatory, showcasing the evolution of Kepler's Supernova Remnant. The footage is the longest-spanning video ever released by Chandra and provides unprecedented insights into the behavior of a Type Ia supernova.
Kepler's Supernova Remnant was first spotted in 1604 and is located approximately 17,000 light-years away from Earth. It's a remnant of a white dwarf star that exploded when it exceeded its critical mass, after being pulled material from a companion star or merging with another white dwarf. This kind of supernova is crucial for measuring the expansion of the universe.
The video includes X-ray data collected in 2000, 2004, 2006, 2014, and 2025. These datasets were used to create highly detailed visuals, resulting in a 25-year timelapse-style video of the growing remnant. The footage reveals a cloudy neon blue ring with a diagonal cross-line stretching from top to bottom.
As the video cycles through the different datasets, the ring expands like a slowly inflating balloon. Researchers have determined that the bottom of the remnant is expanding at approximately 13.8 million miles per hour (2% of the speed of light), while the top appears to be expanding at around 4 million miles per hour (0.5% of the speed of light). This significant difference in speed is due to the varying density of gas towards the top and bottom of the image.
The team used this data to study the environment into which the white dwarf star exploded, providing crucial information about how remnants change over time. According to Brian Williams, principal investigator of the new Chandra observations of Kepler, understanding supernova explosions and the elements they disperse is essential for knowing our cosmic history.
This latest release from NASA's Chandra X-ray Observatory highlights the significance of studying these celestial events and offers a unique window into the universe's evolution.
