Scientists propose nuking solution to Doomsday asteroid — as thousands of city-killers swarm Earth

The tiny helicopter Nasa built to survive 30 days on Mars ended up flying for nearly three years

Mars was once covered in rivers and lakes, and the mystery of where all that water went now has two answers: some was stripped away into space, and a great deal of it may still be there, locked deep in the planet's crust

Jupiter's moon Europa may have signs of life in its buried ocean

NASA's Nancy Grace Roman Space Telescope, launching on a Falcon Heavy on 30 August 2026, carries a mirror the size of Hubble's but sees a patch of sky about a hundred times wider, built mainly to map dark energy and hunt for planets

Electric air taxis are transitioning from perpetual promise to active deployment as commercial operations begin.

Saturn's moon Titan has an atmosphere thicker than Earth's and seas you could sail on, and it is the one place beyond Earth where a person could stand outside without a pressure suit, though its surface sits at about minus 179 degrees Celsius

Mars has such thin air that around noon near the equator, sunlit ground beneath your boots could reach 24 degrees Celsius while the air around your head remained below freezing — allowing one standing person to span temperatures resembling spring and

Asteroid Apophis, named for the Egyptian god of chaos, will pass closer to Earth on 13 April 2029 than many weather satellites do — roughly 32,000 kilometres from the surface — and up to 90% of the world's population may see it with the naked eye

Europa is smaller than Earth's Moon, yet the ocean locked beneath its ice contains more liquid water than every ocean on Earth combined — kept from freezing not by sunlight, but by Jupiter's gravity squeezing the moon like a slow, endless fist

Titan turns so slowly that one rotation takes almost sixteen Earth days, and it is locked in place, showing Saturn the same face forever — so from one side of the moon the ringed planet hangs permanently in the sky, and from the other it is never seen at

Titan has four seasons much like Earth's, but there is one very strange catch to them: because Saturn takes about 29 years to circle the Sun, a single season on Titan drags on for roughly seven Earth years

The 24-hour day is not fixed but slowly stretching, and in the dinosaurs' time it was shorter: the Moon's pull is gently braking Earth's spin, so a day back then ran about 23.5 hours, and far shorter deeper in the past

Earth’s rotation is not a constant, as the planet experiences a delicate tug-of-war between a drifting Moon and shifting environmental forces.
