X-Ray Data Reveal Origin of Kepler’s Supernova

This composite image of SN 1604 shows Chandra X-ray emission from iron in blue, and also Spitzer infrared (IR) emission in pink. The IR emission is very similar in shape and location to X-ray emission from material that was expelled by the giant star companion to the white dwarf before the latter exploded. This material forms a disk around the center of the explosion (X-ray: NASA / CXC / NCSU / M.Burkey et al; IR: NASA / JPL-Caltech)

New data obtained with NASA’s Chandra X-ray Observatory point to the origin of the supernova SN 1604, the famous explosion that was discovered by the great German astronomer Johannes Kepler in 1604. This composite image of SN 1604 shows Chandra X-ray emission from iron in blue, and also Spitzer infrared (IR) emission in pink. The IR emission is very similar in shape and location to X-ray emission from material that was expelled by the giant star...

This image combines data from ALMA and Hubble. Shown in red is the distant, background galaxy, being distorted by the gravitational lens effect produced by the galaxy in the foreground, shown in blue as measured by Hubble. The background galaxy appears warped into a so-called Einstein ring: a circle of light around the foreground galaxy (Dan Marrone)
