Space and Technology

The nearest world that might host life is just 4.2 light-years away — but at the speed of the fastest spacecraft humanity has ever flown, the trip would take 75,000 years, and the one serious plan to go faster has quietly collapsed

Just over four light-years away, the Alpha Centauri system holds the closest worlds beyond our own that might support life. One, Proxima Centauri b,...

On November 18, 2026, Voyager 1 becomes the first thing humanity has ever built to sit a full light-day away — a full day for any signal to reach it.

On November 18, 2026, Voyager 1 will cross a milestone no machine has ever reached: it will sit a full light-day from Earth. From...

A NASA space telescope is falling out of the sky, and to save it the agency skipped its own contractors and handed the job to a four-year-old startup that had never flown a spacecraft — nine months and $30 million after its own $2 billion rescue program collapsed.

The Neil Gehrels Swift Observatory has spent 21 years as astronomy's first responder, swinging toward exploding stars faster than any other telescope. Now it...

Nearly 18,000 People Applied to Be NASA Astronauts. About 12 Made It.

NASA receives 12,000 to 18,000 applications in a typical astronaut cycle and selects about ten to twelve people, an acceptance rate well below one...

NASA's Nancy Grace Roman Space Telescope, launching in 2026, is expected to find around 100,000 planets beyond our solar system in a single mission — after nearly 30 years of searching, astronomers have confirmed roughly 6,000.

NASA already flies two famous space telescopes, Hubble and James Webb. A third is almost ready: the Nancy Grace Roman Space Telescope, launching in...

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.

Space and Technology

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...

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...
