Anew study has uncovered surprising details about the nature of ice in space, challenging long-held assumptions about how ...

But space is different in two extremely important ways: it’s cold (especially if you’re not in direct sunlight, or farther away from our star), and it’s the best pressureless vacuum we know of.

NASA says with the help of data from the James Webb Space Telescope, scientists have confirmed the presence of water crystals around a Sun-like star, some 155 light-years away from Earth. The star ...

She says if you add up all the water that astronauts either sweat out or breathe out as moisture, it's about 1 1/2 liters per day per person. WILLIAMSON: That is about 50% of our water that we do ...

Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 ...

Illustration of silica crystals coming out from the liquid metal of the Earth's outer core due to a water-induced chemical reaction. Their research was recently published in Nature Geoscience .

A new study has revealed that water from the Earth's surface can penetrate deep into the planet, altering the composition of the outermost region of the metallic liquid core and creating a ...

It is made of water, with a three-dimensional form that doesn’t get its shape from any vessel and as such cannot exist on earth, but only in outer space in the absence of gravity.

A new series of experiments has shown that the mysterious "E-prime layer," which surrounds Earth's outer core, is created by water that leaks deep into our planet's interior.
