Latest Ultraluminous X-ray source Stories
At this time of year, there are lots of gatherings often decorated with festive lights. When galaxies get together, there is the chance of a spectacular light show as is the case with NGC 2207 and IC 2163
Imagine how brightly our Sun shines on a warm summer day. Now, try to imagine a star approximately 10 million times brighter. A team of astronomers have discovered such a pulsating star.
The Nuclear Spectroscopic Telescope Array, or NuSTAR, recently spotted the brightest pulsar ever recorded using X-ray optics designed by a team that included researchers from the Lawrence Livermore
Approximately 12 million light years from Earth is a galaxy called NGC 7793, and just on the outskirts of this galaxy is a black hole, designated P13, which new research has revealed is ingesting a weight equivalent to 100 billion billion hot dogs every minute.
WASHINGTON, Oct. 8, 2014 /PRNewswire-USNewswire/ -- Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns.

Our understanding of how some black holes consume matter might be changed by new observations of a black hole powering an energetic X-ray source in a galaxy some 22 million light years away.
Black holes are known to either come in masses of only about 10 times that of our sun, or the equivalent in mass of up to 10 billion suns. However, NuSTAR could be finally finding a middle ground.
NASA’s Chandra X-ray Observatory caught signs of what appeared to be a black hole eating gas at the middle of the nearby Sculptor galaxy nearly a decade ago. A new observation by NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has found the black hole asleep.
