Kepler’s Supernova Remnant: Views from Chandra, Hubble, and Spitzer

These images represent views of Kepler's supernova remnant taken in X-rays, visible light, and infrared radiation.
Each top panel shows the entire remnant. Each color in this image represents a different region of the electromagnetic spectrum, from X-rays to infrared light. The X-ray and infrared data cannot be seen with the human eye. Astronomers have color-coded those data so they can be seen in these images.
The bottom panels are close-up views of the remnant. The region seen in these images is outlined in the top row of pictures. In the bottom, center image, Hubble sees fine details in the brightest, densest areas of gas.
The images indicate that the bubble of gas that makes up the supernova remnant appears different in various types of light. Chandra reveals the hottest gas [colored blue and colored green], which radiates in X-rays. The blue color represents the higher-energy gas; the green, the lower-energy gas. Hubble shows the brightest, densest gas [colored yellow], which appears in visible light. Spitzer unveils heated dust [colored red], which radiates in infrared light.

NASA's Great Observatories Provide a Detailed View of Kepler's Supernova Remnant
NASA's three Great Observatories - the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory - joined forces to probe the expanding remains of a supernova, called Kepler's supernova remnant, first seen 400 years ago by sky watchers, including...
Shock Wave in Kepler's Supernova Remnant
Detailed knots and filamentary ribbons of glowing gas are apparent in this Hubble Space Telescope image of Kepler's supernova remnant. This image was taken with Hubble's Advanced Camera for Surveys (ACS) in August 2003. Filters onboard Hubble isolate visible light emitted by...

Zoom-In to Kepler's Supernova Remnant
This "zoom" starts in the Scorpius constellation and pushes through deeper and narrower telescopic fields to at last reach Kepler's supernova remnant, a composite of images from NASA's Chandra X-ray Observatory, Hubble Space Telescope, and Spitzer Space Telescope.

Chandra, Hubble, Spitzer Composite View of Kepler's supernova
The composite view of Kepler's supernova splits into its three components: blue-green for Chandra, yellow for Hubble, and red for Spitzer. Each observatory's full image is then shown for side-by-side comparison, beginning with Chandra, then Hubble, and finally Spitzer.
