It looks like a deformed red snowman, orbiting the Sun from the icy reaches well beyond Pluto. New research has provided a more detailed picture of the most distant object we've ever visited New ...

Jupiter's rapid early growth dramatically reshaped our solar system, scientists now reveal. Its immense gravity acted as a cosmic divider, separating materials and influencing where planets formed.

About 13.8 billion years ago, the universe began in a big bang. With it was born space, time and a fiery soup of exotic subatomic particles. Of this, cosmologists are reasonably confident. In the ...

Solar system birth Our solar system was born thanks to the death of a nearby star in a spectacular supernova event, say researchers. The findings are based on new computer simulations developed by Dr ...

Scientists have long puzzled over how our solar system’s planets formed, because this isn’t a process they can watch unfold. Researchers have generally thought that Jupiter and Saturn grew out of ...
