Exploding star provides hint on how dark matter warps light in the universe
An exploding star has been seen by astronomers four separate times as a result of dark matter affecting the image, an Australian researcher has revealed.

A team of international scientists studying space using the Hubble Telescope found a supernova explosion appeared multiple times in different places due to the impact of gravitation on light :: Read the full article »»»»


Astronomers Discover Largest Black Holes EVER!?

Black HoleScientists have discovered the two biggest black holes ever observed, each with a mass billions of times greater than the Sun’s, according to a study published overnight. The two giants are located in the heart of a pair of galaxies several hundred million light years from Earth, the study was published in the scientific journal Nature.

Each black hole is estimated to have a mass about 10 billion times greater than the sun, dwarfing the previously largest-known black hole, which has a mass of 6.3 billion suns. The University of California, Berkeley, team led by Nicholas McConnell and Chung-Pei Ma said one black hole is located in NGC 3842, the brightest of a cluster of galaxies about 320 million light years from Earth. The second hole is of “comparable or greater mass” and is located in NGC 4889, the brightest galaxy in the Coma cluster, about 335 million light years away.

“These two black holes are significantly more massive than predicted,” the astronomers wrote.

The researchers said their calculations suggest that different evolutionary processes influence the growth of the largest galaxies and their black holes than in smaller galaxies. Astronomers have long supposed that since the universe began it has harboured black holes with a mass the size of the two newly found giants. These cosmic gluttons grow in tandem with their galaxies, slurping up gases, planets and stars :: Read the full article »»»»
