Theory of relativity

Astronomers identified the largest stellar black hole yet discovered in the Milky Way, with a mass 33 times that of the Sun, according to a study published on Tuesday.

One of the largest black holes ever recorded has been discovered using a new technique that could spot thousands more of the insatiable celestial monsters in the coming years, according to astronomers.

The ultramassive black hole, one of just four ever observed, is more than 30 billion times the mass of the Sun, a new study said.

A new study shows that extreme black holes could break the famous “no-hair” theorem, and in a way that we could detect

Scientists were shocked to find that three years on a black hole came back to life…throwing out material

Astronomers first noted the existence of the rogue black hole in 2011

The change could be far more fundamental, suggesting for instance that Einstein’s general theory of relativity could need replacing

One black hole is nice, but astrophysicists can do a lot more science with 50 of them

Scientists have discovered a black hole just 1,000 light years from Earth, the European Southern Observatory announced on May 6.

The black hole, which boasts a mass more than four-times that of our sun, is the closest to Earth known to exist. It was detected in the HR 6819 triple system in the Telescopium constellation.

A Turkish astrophysicist professor has begun work on a new U.S. National Aeronautics and Space Administration (NASA) project to create a powerful space telescope.

Professor Feryal Özel, the only Turkish woman scientist at NASA, is already managing a project for an event horizon telescope that aims to monitor a black hole.
