NASA's Nuclear Spectroscopic Telescope Array has turned its gaze from distant black holes and focused on our sun, producing the most sensitive measurement of high-energy solar X-rays ever achieved.
This image, a composite of x-ray, infrared, and optical data, shows the most massive galaxy cluster ever discovered at its distance: a staggering 9.6 billion light-years away, altogether containing the equivalent mass of 400 trillion suns. Continue reading →
Astronomers may finally have detected a signal of dark matter, the mysterious and elusive stuff thought to make up most of the material universe.
A black hole is eating a star faster than scientists had thought was possible, and it's unleashing unusually bright X-ray signals that may help scientists understand a group of weird, superbright objects in deep space.
Through the analysis of light from distant galactic clusters, astronomers have detected a mysterious signal that they're having a hard time explaining. Continue reading →
Astrophysicists have analyzed two decades-worth of X-ray data and discovered three events inside galactic cores that can be interpreted in only one way: stellar destruction. Continue reading →
To celebrate 15 years in orbit, NASA has release new, mind-blowing views of the Chandra X-ray observatory's most famous supernova remnants.
The complex violence of a galactic cluster four-way has been recorded 5 billion light-years distant and astronomers don't yet fully understand what they are witnessing. Continue reading →
