A highly sensitive radio telescope has seen something peculiar in the depths of our cosmos: A group of supermassive black holes are mysteriously aligned, as if captured in a synchronized dance.
Scientists have discovered radioactive debris from relatively nearby stars that exploded a few million years ago, raising questions about whether cosmic rays released by the supernovae impacted Earth’s past climate.
Astronomers have found a monster black hole, some 17 billion times more massive than the sun, in a modestly sized galaxy, raising suspicions that supermassive black holes may be much more common than originally thought.
From the brightest supernovae to the blackest of holes, space sure knows how to provide extremes. But, it's not as easy as just taking a look to decide which objects are how bright or dark. DNews crunches the numbers.
Tune in tonight at 7 p.m. for a fascinating Perimeter Institute public lecture on the mysteries of dark matter.
An enterprising artist has taken on one of the biggest concepts known to man: the universe.
In new observations, an extremely concentrated knot of ancient galaxies undergoing energetic star formation at the dawn of our universe has been spied embedded in a knot of dark matter.
Astronomers have detected something baffling at the furthest frontiers of our observable universe: lots of massive galaxies that shouldn't even exist.
