This supermassive black hole, with millions to billions times the mass of our sun, lies at the heart of a galaxy called NGC 1365 and it is spinning almost as fast as Einstein’s theory of gravity will allow, nearly at the speed of light. Image © NASA/JPL-Caltech
The Jake Matijevic rock that Curiosity explored for several days on Mars, is marked by red dots indicate areas where the rover shot the rock with laser blasts and purple circles indicate areas investigated with X-rays beams. Image credit: NASA/JPL-Caltech/MSSS
Astronomers using NASA‘s Swift satellite recently detected a new black hole, by a rise in high-energy X-rays from a source toward the center of our Milky Way galaxy. The outburst, produced by a rare X-ray nova, came from a previously unknown stellar-mass black hole. Image credit: NASA’s Goddard Space Flight Center
Nick Veasey uses x-ray technology to create photographic works revealing the structural anatomy of a range of subjects from small animals, plants, insects, toys, cars. Some of them require industrial x-ray facilities to be captured. © Nick Veasey
The “Black Widow” pulsar is moving through the galaxy at a speed of almost a million kilometers per hour. A bow shock wave due to this motion is visible to optical telescopes, shown in this image as the greenish crescent shape. The pressure behind the bow shock creates a second shock wave that sweeps the cloud of high-energy particles back from the pulsar to form the cocoon.
In late March 2011, NASA’s Swift satellite alerted astronomers to intense and unusual high-energy flares from a new source in the constellation Draco. They soon realized that the source, which is now known as Swift J1644+57, was the result of a truly extraordinary event — the awakening of a distant galaxy’s dormant black hole as it shredded and consumed a star.
