New mathematical technique enables astronomers to predict the whereabouts of missing worlds around nearby stars.
The scariest beast in the universe has an insatiable appetite and shreds its victims.
Researchers have long suspected there's water - or ice, to be precise - on the Moon. New research now confirms it, and suggests it lurks in sun-starved nooks and crannies called 'cold traps'.
OSIRIS-REx will touch down on asteroid Bennu, collect a sample of the dust and begin its journey back to Earth, where scientists will study it, hoping to learn secrets of the solar system's origin.
Surprising findings on an exquisite and huge star system in our Milky Way suggest future potential for an extremely rare gamma-ray burst. This event has never been observed in our galaxy.
The 2020 Nobel Prize in physics was awarded to three scientists – an Englishman, an American and a German – for breakthroughs in understanding the most mysterious objects in the universe: black holes.
News that Venus may harbor life has swept the globe. So how do we find out for sure? A planetary scientist explains what's next.
There is a reason why it's easier to roll marbles down rather than up a hill. And the answer (to this and to gravity itself) is all about acceleration.
