A river longer than England’s Thames flows beneath the Antarctic ice sheet, draining an area the size of France and Germany combined, new research reveals. This under-ice river was discovered using ice-penetrating radar mounted on aircraft. In a series of aerial surveys, researchers discovered a river system snaking 285 miles (460 kilometers) and draining into … Read more
On Dec. 24, 2021, a magnitude 4 marsquake rocked the Red Planet, triggering sensors on NASA’s Insight lander. Now, scientists know exactly what shook things up. Before and after images captured by NASA’s Mars Reconnaissance Orbiter confirmed it was a meteoroid impact –— the largest on record in the entire solar system. The impact crater, … Read more
The massive asteroid impact that killed the dinosaurs also triggered mega-earthquakes that lasted months. Around 66 million years ago, an asteroid approximately 6.2 miles (10 kilometers) across smashed into Earth near the Yucatan Peninsula, plunging the planet into darkness and causing a mass extinction that wiped out 80% of animal life — including all the … Read more
There are deep realms on our planet that seem almost extraterrestrial. Translucent fish flit back and forth while strange, flower-like crinoids sway in the water.

The boundary zone between Earth’s molten metal core and the mantle, its rocky middle layer, might be a diamond factory. A new laboratory experiment finds that, under extreme temperatures and pressures, the combination of iron, carbon and water — all potential ingredients found at the core-mantle boundary — can form diamond. If this process also … Read more
A mysterious Martian mineral that has perplexed scientists since its discovery seven years ago may have been spat out during an unusual volcanic eruption, researchers have revealed. The mineral, which is normally only found on Earth, was likely formed on the Red Planet more than 3 billion years ago. NASA’s Curiosity rover discovered the mineral … Read more
Salt crystals from Central Australia hold ancient microorganisms that became trapped 830 million years ago, new research finds. And there’s a chance that some of the microorganisms might still be alive. The single-celled organisms are locked in tiny fluid pockets — smaller than the width of a human hair — in halite, or salt, from … Read more
An area of Pluto that researchers think was formed from the eruption of ice volcanoes is unique on the dwarf planet and in the solar system, a new study suggests. NASA’s New Horizons mission, which launched in 2006, took detailed photos of the surface of Pluto, a dwarf planet and the largest object in the … Read more
