According to the CDC, 50 countries worldwide have drinkable tap water. But look closer, and the picture is more nuanced.
There are at least 15 different types of solid water (ice). Now, scientists believe that there might be a second type of liquid water.
Finding this missing piece of water’s path through the universe offers clues to how it came to be on Earth.
Exoplanet LP 791-18d is likely to have an atmosphere and liquid water.
Sometimes called “the new gold,” sand is the second most exploited natural resource in the world after fresh water.
While ice itself is slick, slippery, and difficult to navigate across under most circumstances, skaters easily glide across the ice.
Some fascinating observations of K2-18b have come along with horrendous, speculative communications. There's no evidence for oceans or life.
In one experiment, the Viking landers added water to Martian soil samples. That might have been a very bad idea.
In the early stages of our Solar System, there were three life-friendly planets: Venus, Earth, and Mars. Only Earth thrived. Here's why.
While Saturn and its moons all appear faint and cloudy to JWST, Saturn's rings are the star of the show. Here's the big scientific reason.
The Black, Caspian, and Aral Seas are the last surviving fragments of a body of water that stretched from Austria to Turkmenistan.
The divers spend their waking hours either under hundreds of feet of water on the ocean floor or squeezed into an area the size of a restaurant booth.
Figuring out the answer involved a prism, a pail of water, and a 50 year effort by the most famous father-son astronomer duo ever.
Why can’t more rainwater be collected for the long, dry spring and summer when it’s needed?
It's a bird! It's a plane! It's a medieval airship!
Despite the vast number of planets in the Universe, Earth's specific evolutionary history guarantees that its life forms — including humans — are utterly unique.
Decades ago, a disaster left three million acres of land uninhabitable and killed between 85,600 and 240,000 people. Chernobyl? No. Banqiao dam in China.
Although early Earth was a molten hellscape, once it cooled, life arose almost immediately. That original chain of life remains unbroken.
Despite the enormous mass of the Earth, simply depleting our groundwater is changing our axial tilt. Simple Newtonian physics explains why.
Simple physics makes hauling vast ice chunks thousands of miles fiendishly difficult — but not impossible.
The flavor is "simultaneously fascinating and... abusive."
Passing chunks of ice can fertilize ocean waters and play a role in the planet’s carbon cycle.
About six million years ago, the Mediterranean was sealed off from the Atlantic, and over centuries it ran dry. One megaflood reversed that.
It could make enough drinking water for a family of four.
Most of us only ever see a fraction of a full rainbow: an arc. But optically, a full rainbow makes a complete circle. Physics explains why.
Once water gets more than about 200 feet deep, building on the sea floor is out of the question.
In the 1960s, politicians and bureaucrats were formulating the Central Arizona Project. Citizens fought back.
