Uranus is a lopsided oddity, the only planet to spin on its side. Scientists now think they know how it got that way: It was pushed over by a rock at least twice as big as Earth.
It was another great year for science, and physics was front and center, as a team at the University of Oxford announced that they may have solved one of the biggest mysteries in modern physics. They came up with a new theory ...
Jamming and astrophysics go hand-in-hand for Queen lead guitarist Brian May, who announced Wednesday he is releasing a musical tribute to a far-flung NASA spacecraft that is about to make history.
With no apparent hazards in its way, NASA's New Horizons spacecraft has been given a "go" to stay on its optimal path to Ultima Thule as it speeds closer to a Jan. 1 flyby of the Kuiper Belt object a billion miles beyond ...
Around 4 billion years ago there lived a microbe called LUCA: the Last Universal Common Ancestor. There is evidence that it could have lived a somewhat 'alien' lifestyle, hidden away deep underground in iron-sulfur rich hydrothermal ...
A team of astronomers has discovered the most-distant body ever observed in our Solar System. It is the first known Solar System object that has been detected at a distance that is more than 100 times farther than Earth is ...
In their search for life in solar systems near and far, researchers have often accepted the presence of oxygen in a planet's atmosphere as the surest sign that life may be present there. A new Johns Hopkins study, however, ...
The Geminids meteor shower peaks on the mornings of December 13 and 14, 2018 – but if you look up any time there's a clear night sky up until December 17, you might just catch a glimpse of a Geminid meteor.
By developing a new method for measuring isotopic ratios of water and carbon dioxide remotely, scientists have found that the water in Saturn's rings and satellites is unexpectedly like water on the Earth, except on Saturn's ...
