Scientists used a process called 'diffusioosmosis' to write words that lingered in liquid water.
Ice can form on Earth at temperatures above 32 degrees Fahrenheit (0 degrees Celsius), and water can boil below 212 F (100 C). Here's how.
Whether it's from a day at the beach or a trip to the swimming pool, getting water stuck in your ear is very common. But how does it happen?
Some of the moon's surface water may have an Earthly origin, due to high-energy interactions between the sun and Earth's magnetic shield, new research suggests.
NASA's James Webb Space Telescope has detected potential traces of dimethyl sulfide, a chemical only known to be created by phytoplankton on Earth, in the atmosphere of an exoplanet believed to have its own liquid ocean.
One researcher hypothesizes that experiments carried out by NASA's Viking landers in 1976 could have inadvertently killed microbes living in Martian rocks. Other experts are skeptical.
A patchwork of polygon-shaped cracks in ancient Martian mud are evidence of past wet-dry cycles, which could have helped extraterrestrial life emerge on the Red Planet.
The magma that erupts from basaltic volcanoes in the middle of tectonic plates originates from within Earth's mantle — rather than from the outer crust — and is propelled upward by CO2, not water.
