A supermassive black hole is really large by its weight, and it is a billion-solar-mass object.
Two supermassive "black holes" are found in galaxies near the Earth. These had been discovered with the use of NASA's space-based telescope the Nuclear Spectroscopic Telescope Array.
In a paper recently published in peer-reviewed Physical Review Letters, Stephen Hawking and his co-authors suggested that black holes may potentially lead to another universe. The paper contradicts the idea that black holes have ‘no hair’ saying that a so-called ‘halo of hair’ captures low-energy quantum excitations.
A new study found that the black holes are just a light-week away from each other and could collide in about 100,000 years.
The study however claims that such black holes may not succeed in consuming the universe.
Discovery of five supermassive black holes recently has led astronomers to believe that there could be millions of them across the universe.
Using the Hubble Telescope, astronomers were associated plasma jet emissions from galactic cores to merger of black holes.
The observatories were dedicated on Wednesday. Scientists hope to detect gravitational waves which were predicted by Einstein.
The quartet was found engulfed in a massive nebula of cold and dense gas, surprising astronomers who spotted the objects.
A new study argues that a quasar emitting periodically indicates cyclic absorption of matter by merging black holes to form a binary black hole.
Repairs could take weeks as the magnetic sector is cryogenically cooled.
In spite of a motor neuron disease, Stephen Hawking is a feisty scientist with earth-shattering theories and an interesting way with words.
