Scientists discover the smallest ever black hole

November 01, 2019 5:32 pm

Space scientists have found out a tiny black hole that could fall under a totally different class of objects. It has a size of 3.3 solar masses and is located near a huge star 2MASS J05215658+4359220.

Indian, British astronomers discover new details of black hole 10,000 light years away

The new visualisation of a black hole by NASA illustrates how the gravity of the giant celestial structure distorts our view, warping its nearby surroundings. It has been created with the help of a custom software at NASA's Goddard Space Flight Center.

Scientists ponder over discovery of 'physically impossible' black hole

September 05, 2019 8:32 am

Scientists are analysing the gravitational-wave signals provided by LIGO and Virgo interferometer that provide details of a giant black hole which is so huge that until now has been thought to be physically impossible. So far, they have refused to confirm or deny the detection.
