This composite image, from NASA's Galileo and Mars Global Survey orbiters, of Earth and Mars was created to allow viewers to gain a better understanding of the relative sizes of the two planets.

Mars once had rivers, lakes, and possibly oceans, and it lost all of them for one reason — its molten core cooled, its magnetic field died, and the solar wind stripped the planet’s air into space.

Mars wasn't always frozen and barren. Billions of years ago it had flowing rivers, standing lakes, and possibly oceans. It lost all of it...

Space and Technology

In January 2005 a European probe named Huygens fell for two and a half hours through the orange haze of Titan and landed on a plain of ice — the most distant touchdown in history, and no spacecraft has ever gone back.

Most probes orbit worlds or fly past them. In January 2005, Europe's Huygens did something far rarer: it landed. Carried across the solar system...

In 1965, Russian cosmonaut Alexei Leonov stepped outside Voskhod 2 for the first spacewalk in history, and his suit ballooned so badly in vacuum that he had to bleed oxygen through a valve to fit back inside before orbital darkness

On 18 March 1965, the Soviet Union sent Alexei Leonov outside Voskhod 2 for the first spacewalk in history. The mission became a Space...

At 70,000 Feet, Olympus Mons on Mars Stands Two and a Half Times Taller Than Mount Everest. It Is the Largest Volcano in the Solar System, and It May Not Be Extinct

A person standing on the largest volcano in the solar system would never know it. Olympus Mons rises 70,000 feet over Mars on slopes...

NASA Has Not Launched Anything Faster Than Voyager in 48 Years. Here Is the Real Menu of Machines That Could Finally Beat It

Voyager 1 is about to become the first object one light-day from Earth, still whispering home on a plutonium supply the size of a...

This artistic impression depicts our Solar System neighbour Venus, where scientists have confirmed the detection of phosphine molecules. The molecules were detected in the Venusian high clouds in data from the James Clerk Maxwell Telescope and the Atacama Large Millimeter/submillimeter Array, in which ESO is a partner. Astronomers have speculated for decades that life could exist in Venus’s high clouds. The detection of phosphine could point to such extra-terrestrial “aerial” life.

Terraforming Venus means removing 90 Earth atmospheres of carbon dioxide, cooling a planet that melts lead, and importing an ocean — the newest NASA idea skips all of it

Venus crushes, roasts, and corrodes anything that touches it, and it has almost no water. But fifty kilometers up, the pressure matches Earth's —...

The ‘Best Fighter Never Produced’: Vought’s Crusader III Outflew the F-4 Phantom, Then Lost Everything in 48 Hours

In December 1958, the U.S. Navy chose the F-4 Phantom over a Vought fighter that was faster, lighter, and cheaper — the better airplane,...

NASA’s Space Shuttle Hit Mach 25 on 133 Flights: The Fastest Crewed Aircraft Ever Holds No Speed Record

In 1967, Pete Knight flew Mach 6.72 and was called the fastest man alive. For thirty years, the Space Shuttle made that number look...

Space and Technology

After walking on the Moon, the Apollo 11 crew spent three weeks locked in quarantine — in case they’d brought back lunar germs — and greeted the world through glass.

The first men on the Moon came home to a locked box. For three weeks after splashdown, Neil Armstrong, Buzz Aldrin, and Michael Collins...
