In 2007, astronomers discovered the Cosmic Horseshoe, a gravitationally lensed system of galaxies about 5.5 billion ...

Binary black holes, systems consisting of two black holes in close orbit around each other, synchronize their spins before they merge together, according to new research. The moment creates a ...

Gamma rays detected by NASA's Fermi spacecraft indicate that microquasars are powered by small black holes slowly devouring ...

However, a new simulation revealed just in time for Feb. 14 shows how dancing black holes can "vibe" with one another, forming a cosmic love story that is literally written in the stars. More ...

The extreme velocity of J0731+3717 resolves this debate. "Such a high-speed ejection requires a tight binary star to pass ...

More precisely, the team behind the simulation discovered that binary black hole pairs formed in dense star clusters first align their spins before coming together and merging. The discovery could ...

Fast-moving stars in the Milky Way indicate there could be a supermassive black hole in the neighboring Large Magellanic ...

An international team of researchers has detected a binary star orbiting near Sagittarius A*, the supermassive black hole located at the center of our galaxy. This is the first time a pair of stars ...
