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)


SXP 1062 in 60 Seconds

View/Listen
Narrator (April Hobart, CXC): The Milky Way galaxy has several small satellite galaxies very close to it. One of them is called the Small Magellanic Cloud. Astronomers using several telescopes - including the Chandra X-ray Observatory - spotted an unusual object in the SMC. The source is known as SXP 1062 and may be the first pulsar found within the remains of a supernova explosion. X-ray data from Chandra and XMM-Newton also show that SXP 1062 is rotating unusually slowly - about once every 18 minutes. In contrast, some pulsars are found to revolve multiple times per second, including most newly born pulsars. Scientists have determined the pulsar was born between ten and forty thousand years ago. While this may sound like a long time, it is a blink of an eye in astronomical terms. Therefore, it is a mystery why SXP 1062 has been able to slow down by so much, so quickly.
