ملف:25 Images to Celebrate NASA’s Chandra 25th Anniversary- Crab Nebula (53893798390).jpg

English: To celebrate the 25th anniversary of its launch, NASA’s Chandra X-ray Observatory is releasing 25 never-before-seen views of a wide range of cosmic objects.

These images, which all include data from Chandra, demonstrate how X-ray astronomy explores all corners of the universe. By combining X-rays from Chandra with other space-based observatories and telescopes on the ground, as many of these images do, astronomers can tackle the biggest questions and investigate long-standing mysteries across the cosmos.

On July 23, 1999, the space shuttle Columbia launched into orbit carrying Chandra, which was then the heaviest payload ever carried by the shuttle. With Commander Eileen Collins at the helm, the astronauts aboard Columbia successfully deployed Chandra into its highly elliptical orbit that takes it nearly one-third of the distance to the Moon.

The Crab Nebula is the result of a bright supernova explosion witnessed by Chinese and other astronomers in 1054 A.D. Chandra sees the rings around the pulsar and the jets blasting into space. X-rays from Chandra (blue-violet and white) and IXPE (purple); optical from Hubble (red, green, and blue)
