Tour of WASP-18
Tour of WASP-18
A new study using data from Chandra X-ray Observatory has shown that a planet is making the star that it orbits act much older than it actually is. (2014-09-18)


Hydra A in 60 Seconds

View/Listen
Narrator (Megan Watzke, CXC): This composite image of the Hydra A galaxy cluster shows 10-million-degree gas observed by Chandra and jets of radio emission observed by the Very Large Array. The galaxies in the cluster are seen in optical light by two ground-based telescopes. At the center of Hydra A is a supermassive black hole that has experienced powerful outbursts. These outbursts pushed the material surrounding the black hole, creating giant cavities seen in the Chandra data. These cavities were then filled with material from jets seen in the radio data. The Chandra data reveal that the gas located along the direction of the radio jets is enhanced with iron and other metals. Scientists think that these elements, vital for stars, planets, and ultimately life, were forged in supernova explosions in the large galaxy at the center of the cluster.
