A pair of dazzling images from NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) highlights the observatory's impressive imaging capabilities for objects both near and far.
A surprising new class of hypervelocity stars has been discovered by an international team of astronomers.
Scientists have discovered a rare celestial entity that could help test predictions of Albert Einstein’s theory of general relativity.
NASA’s Chandra X-ray Observatory has helped astronomers witness the first event of a black hole destroying a star in a dwarf galaxy.
NASA astronomers have found evidence of two supermassive black holes at the center of a remote galaxy that are locked in a fierce, circling dance.
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.
Many supermassive black holes emit a jet of high-energy particles as a byproduct of engulfing large quantities of mass and energy, and NASA researchers have just discovered that the supermassive black hole at the center of the Milky Way is no different.
Supermassive Black Hole -- A Supermassive black hole is a black hole with a mass in the range of millions or billions solar masses. A supermassive black hole has some interesting properties differing from his low-mass cousins: -- The average density of a supermassive black hole can be very low, and actually can be lower than water's density. This happens because the black hole diameter increases linearly with mass, and consequently density drops much faster. -- Strong tidal...
