What’s the biggest thing in the universe? Find out here, along with 9 other incredible astronomical wonders.
NASA/JPL-Caltech For the first time ever, scientists have been able to measure the precise spin rate of a ‘supermassive black hole’. The findings will provide some clue as to how some of the most mysterious objects in our universe began to form. The black hole is located in the NGC 1365 galaxy, located 56 million [...]
Meet the new record-holder for the LARGEST BLACK HOLE IN THE UNIVERSE (so far) in this EXPANDED and UPDATED version (in 1080p) of our most popular Cosmic Journeys episode.

In a new study that was recently published in ‘Science,’ astronomers from all over the world assessed data from an array of four linked radio dishes located in Arizona (the Submillimeter Telescope), Hawaii (the James Clark Maxwell Telescope) and two from CARMA in California — which created a ‘super telescope’ capable of seeing details of [...]
Esther Inglis-Arkell Pretty much anything could, in theory, become a black hole if it were squeezed down small enough. At what point would the Earth become a (very unimpressive) black hole in space? We’re going to figure it out, and tell the tale of the Schwarzschild Radius. Karl Schwarzschild is one of those people [...]
