Astronomers using NASA’s Chandra X-ray Observatory have detected an extragalactic candidate planet circling a binary system in Messier 51 (also known as M51, the Whirlpool Galaxy and NGC 5194), an interacting grand design spiral galaxy located some 26 million light-years away in the constellation of Canes Venatici.
New images from NASA’s Chandra X-ray Observatory show small knots of metal-rich debris in the remnant of Kepler’s supernova, also known as SN 1604, are moving up to 37 million km per hour (23 million mph). These are extremely high speeds for an explosion that happened over 400 years ago as seen from Earth.
Astronomers have uncovered a supermassive black hole that has been propelled out of the center of a distant galaxy by what could be the awesome power of gravitational waves.
Astronomers have found evidence of a star that whips around a likely black hole twice an hour. This could be the tightest orbital dance ever seen by a black hole and a companion star in our own Milky Way galaxy.
A small but distinctive signal in X-rays from the Milky Way could be key to proving the existence of dark matter.
A black hole 11 million light-years away has gone dormant, a decade after being spotted consuming cosmic debris.
Astronomers have used NASA’s Chandra X-ray Observatory to show that, multiple eruptions from a supermassive black hole over 50 million years have rearranged the cosmic landscape at the center of a group of galaxies.
Space is beautiful. These are nine images of the most beautiful sights we have of space that people have taken pictures of.
Astronomers have discovered the second-strongest merger shock in clusters of galaxies ever observed.
