Earth's coastlines are fascinating places where liquids mix and materials are shaped into distinct landforms like river deltas.

Chinese rover finds underground evidence of beach sediments likely deposited 4 billion years ago

The delta smelt was bound for extinction years ago, but it's still a red flag signifying political ignorance on the right.

About 50 Senegalese women climate activists hit the streets of Dakar Saturday to demand climate justice ahead of COP29 in a march held annually since 2021...

What do Venice, Jakarta, Manilla and Bangkok have in common? They are or were sinking cities. Wageningen researcher Philip Minderhoud studies the causes of subsidence in these cities. Groundwater extraction plays an important part in all cases. The good news is that this can be avoided.

An underground Martian ocean could hold enough liquid to cover the Red Planet with a mile of water

New data about the Martian crust gathered by NASA's InSight lander allowed geophysicists to estimate that the amount of groundwater could cover the entire planet to a depth of between 1 and 2 km.

The Perseverance rover has found evidence in a leopard-spotted rock that could suggest microbial life once existed on Mars billions of years ago, NASA said.

Beneath the Antarctic ice, scientists find remnants of a giant river system that flowed for thousands of miles

These samples are uniquely important for return to Earth for further study.

In May 2017, NASA's Curiosity rover observed higher than usual amounts of manganese in the lakebed rocks within Gale crater, Mars.

Volcano detectives use artificial intelligence to sleuth out ancient secrets in Alaska.

Every day, farmer Nguyen Hoai Thuong prays in vain for rain to fall on the cracked dry earth of her garden in Vietnam's Mekong Delta—the country's "rice bowl" agricultural heartland.

So much water, it could have rivaled Earth.

The Australian continent is now geologically stable. But volcanic rocks, lava flows and a contemporary landscape dotted with extinct volcanoes show this wasn't always the case.

NASA's Perseverance rover is equipped with a radar imager, allowing researchers to create a subsurface profile of Jezero Crater to better understand its...

If life ever existed on Mars, the Perseverance rover's verification of lake sediments at the base of the Jezero crater reinforces the hope that traces might be found in the crater.

The NASA Mars Helicopter, Ingenuity, is now responsive after losing communications for several days.

If you really want to know how much Australia contributes to the amount of carbon dioxide (CO₂) in the atmosphere, you have to study all the "sources" and "sinks."

NASA's Perseverance rover hit a big milestone today (Dec. 13) — 1,000 Mars days, or sols, on the Red Planet.
