We measure the extremely long distances between things in space by light years. A light year is the distance that light travels in one Earth year. Light travels at about 300,000 kilometres per second.

Scientists had assumed that the ice in space was purely amorphous, but new experiments show it can have a partly crystalline ...

Strange cone-shaped rocks led scientists to the hidden remains of one of Earth’s oldest asteroid impacts. It could help us find fossil life on Mars.

The Universe’s most abundant ice isn’t formless—it’s secretly laced with crystals. And that might change how we think about ...

How did Earth, alone among the solar system's rocky planets, become the home for life? How, among all this frigid ...

Ice in space, long believed to be completely disordered like frozen water without structure, is turning out to be more complex. New research from (UCL) and the University of Cambridge has shown that ...

NASA has confirmed the discovery of an Earth-sized planet parked right in the “habitable zone” of a distant red dwarf star.

"Space ice" contains tiny crystals and is not a completely disordered material like liquid water, as previously assumed, ...

Ancient oceans with phosphorus-rich waters may have supported some of Earth’s earliest microbial life, according to a new ...

Micrometeorites raining down from space may have provided the perfect surfaces for the first primitive cells to form on Earth ...

Why is Mars barren and uninhabitable, while life has always thrived here on our relatively similar planet Earth?

In a groundbreaking discovery, astronomers have detected a young star system, HD 100453, awash in alcohol, approximately 330 light-years away. This pr ...
