A Tour of The Big, Bad & Beautiful Universe with Chandra
A Tour of The Big, Bad & Beautiful Universe with Chandra
To celebrate the 15th anniversary of NASA's Chandra X-ray Observatory, we have released four new images of supernova remnants. These show Chandra's ability to study the remains of supernova explosions, using images that are the sharpest available in X-ray astronomy. The images of the Tycho and G292.0+1.8 supernova remnants show how Chandra can trace the expanding debris of an exploded star. The images show shock waves, similar to sonic booms from a supersonic plane, that travel through space at speeds of millions of miles per hour. The images of the Crab Nebula and 3C58 show the effects of very dense, rapidly spinning neutron stars created when a massive star explodes. These neutron stars can create clouds of high-energy particles that glow brightly in X-rays. The image for G292 shows oxygen (yellow and orange), and other elements such as magnesium (green) and silicon and sulfur (blue) that were forged in the star before it exploded. For the other images, the lower energy X-rays are shown in red and green and the highest energy X-rays are shown in blue. (2014-07-22)


CH Cyg in 60 Seconds

View/Listen
Narrator (Megan Watzke, CXC): Deep within this optical image lies an intriguing system known as CH Cyg. CH Cyg is a binary star system containing a white dwarf that feeds from the wind of a red giant star. The material from the wind forms a hot accretion disk around the white dwarf before crashing onto the star. CH Cyg is one of only a few hundred so-called symbiotic systems known, and one of the closest to Earth at a distance of only about 800 light years. By combining X-ray data from Chandra, optical data from Hubble, and radio data from the Very Large Array, scientists can study CH Cyg like never before. This image shows material in a jet, moving with a speed of over three million miles per hour, powered by material spinning into the accretion disk around the white dwarf. Systems like CH Cyg are fascinating objects because the components are codependent and influence each other's structure, daily life, and evolution.
