Water

A reanalysis of the data from the "rubber-ducky" comet 67P, collected nearly a decade ago, suggests comets may have deposited a lot more water on Earth than scientists previously thought.

NASA satellites discovered that Earth's surface has lost enough water to empty Lake Erie two and a half times since 2015. And the problem could be here to stay.

A new study captured never-before-seen footage of hydrogen and oxygen atoms combining to form a miniature water droplet out of "thin air." The newly improved reaction could one day help astronauts make water in space.

Drinking water triggers a variety of complex biochemical reactions that reward rehydration and help satiate our thirst.

Researchers think climate change will soon cause an increase in the incidence of Naegleria fowleri infections, a "brain-eating" disease.

Earth from space This 2018 astronaut photo shows the rust-colored waters of Madagascar's Betsiboka River winding through a complex series of mangrove islands. Both the river and islands have been altered in recent years by destructive human practices.

A new water loss mechanism on Venus explains how the planet lost all its water, turning the planet from a potentially habitable world into the parched hellscape we know today.

Earth from space A puzzling arc was spotted in the water of a Greenland fjord littered with iceberg fragments. There are a couple of possible explanations for this bizarre phenomenon but we will likely never know what caused it, experts say.

On April 10, a bright red atmospheric "hole" was spotted in the night sky above Texas shortly after SpaceX launched 23 Starlink satellites into space. It is the latest example of an increasingly common phenomenon caused by the company's dying rockets.

Africa's soda lakes are rising and it's decimating the cyanobacteria flamingos have evolved to eat, putting the species at risk of drastic declines if current trends continue.
