Each year, NASA’s Chandra X-ray Observatory helps celebrate American Archive Month by releasing a collection of images using X-ray data. Each of these six new images — representing just a small fraction of the treasures that reside in Chandra’s unique archive — also includes data from telescopes covering other parts of the electromagnetic spectrum, such as visible and infrared light.
Scientists have determined that comets produce X-ray emission when particles in the solar wind strike the comet’s atmosphere. Recently, astronomers announced the results of a study using data collected with NASA’s Chandra X-ray Observatory of two comets — C/2012 S1 ISON and C/2011 S4 PanSTARRS — when both were relatively close to Earth.
Solar storms are triggering X-ray aurorae on Jupiter that are about eight times brighter than normal over a large area of the planet and hundreds of times more energetic than Earth’s “northern lights,” according to a new study using data from NASA’s Chandra X-ray Observatory when a giant solar storm arrived at the planet.
By combining X-ray data from NASA’s Chandra X-ray Observatory over a 15-year period with radio data from the Australia Telescope Compact Array, astronomers have a better understanding of the active galaxy Pictor A, the supermassive black hole at its core and the enormous jet of particles it generates travelling at nearly the speed of light into intergalactic space.
