Mars looks still from a telescope, a rust-red disk hanging in the sky with no oceans, no forests and no weather systems large enough for the eye to follow.
Saturn's moon Titan has rivers, rainfall, lakes and a slow hydrological cycle uncannily like Earth's — but the liquid is methane, the bedrock is frozen water ice, and the whole system runs at minus 179 degrees Celsius.
In the flooded caves of Slovenia, the blind, pale olm salamander can fast for ten years, sits motionless for years at a time, and lives past 100 in complete darkness.
The most useful thing about compressing Earth's history into a calendar year is not that the timestamps are perfect.
NASA's Psyche spacecraft did not go to Mars because Mars was the destination. It went there because Mars was in the right place to do what rockets would otherwise have had to do with propellant: change the spacecraft's path and speed.
A one-pound rock found in the Sahara in 2019 has become evidence for something much larger than itself: a vanished planetary body from the first years of the solar system.
Europa has earned its place in astrobiology for a simple reason: beneath its fractured ice shell, Jupiter's moon is thought to hold a global saltwater ocean in contact with a rocky interior.
Two humpback whales have done something the species was not supposed to do often: they turned up on opposite sides of the planet, at breeding grounds normally treated as separate populations.
The bone was taller than the man standing beside it. That was the first real clue that the weathered shapes at the edge of a communal pond in Chaiyaphum province, in northeastern Thailand, were not stones.
Each of your kidneys holds roughly one million nephrons, together filtering about 180 litres of blood plasma every day. Sustained high-protein intake measurably raises the pressure inside every one of them — and unlike almost every other tissue in the body, nephrons do not grow back.
The familiar T. rex is an ending, not a life story. The animal most people picture is enormous: deep skull, heavy jaws, thick legs, a body built around the power to bite through bone.
The summit of Everest is usually imagined as the opposite of an ocean floor. It is the highest point on Earth above sea level, a wind-scoured place where the air is thin, the temperature is brutal and the nearest sea lies hundreds of kilometres away.
Let's start with the number that frames everything else. Earlier in 2026, Waymo was giving about 500,000 paid rides a week across its US markets.
The Scott Kelly telomere result is one of those spaceflight findings that sounds almost too neat at first.
A typical AI-focused data centre already sits closer to heavy industry than to the old image of a quiet server room.
On August 2nd 2026, the European Union's rulebook for artificial intelligence stops being a set of deadlines on paper and starts having teeth.
