Looks can be deceiving. The light from an incandescent bulb seems steady, but it actually flickers 120 times per second. Because the brain only perceives…
Hubble Determines Mass of Black Hole Isolated Black Hole Supermassive black holes, such as Sagittarius A* — the black hole at the center of the…
Gravitational waves are ripples in the curvature of spacetime caused by accelerated masses that propagate as waves at the speed of light outward from their…
Gravitational microlensing turns up black hole candidate, one of 200 million in the galaxy. When massive stars come to the end of their lives and…
A deeper understanding of black holes could revolutionize our understanding of physics, but their enigmatic nature makes them difficult to observe. Because the theory of…
The Webb Space Telescope team continues to work on commissioning the science instruments, the final step before starting science operations in the summer. We recently…
Something weird is going on in the galaxy known as 1ES 1927+654: In late 2017, and for reasons that scientists couldn’t explain, the supermassive black…
Newfound black holes in dwarf galaxies shed light on the origin of our galaxy’s supermassive black hole. A team of researchers led by astronomers in…
The Universe contains different “flavors” of black holes. While “stellar” mass black holes are 10-50 times the mass of our Sun, supermassive black holes are…
Astronomers reveal the first image of the black hole at the heart of our galaxy. It is the first direct visual evidence of a ring-like…
This is a sonification — translation into sound — of the latest image from the Event Horizon Telescope (EHT) of the supermassive black hole at…
Team reveals first image of the black hole at our galaxy’s heart. An international team of more than 300 scientists from 80 institutions has created…
