W2246f sits 1.2 billion light years away with an old, quiet central kiloparsec and a still-star-forming disk, but MUSE found no recent collision or active nucleus to explain the galaxy’s split personality

In August 1971, the Apollo 15 astronauts left a small aluminum figurine and a plaque on the Moon called the Fallen Astronaut, listing fourteen Americans and Soviets who had died in the race to get there, and they said nothing about it over the radio, revealing it only after they were safely back on Earth.

In June 2026, behind SpaceX’s plan to sell 555.6 million shares at $135 each, the $1.77 trillion question facing investors was not rockets alone, but Starlink, AI data centers, and Mars inside one company

NASA's plan to put a nuclear reactor on a Mars-bound spacecraft by 2028 sounds impossible — until you realize the agency is quietly stitching together two programs that were never supposed to meet

Sunsets on Mars glow blue rather than red, because the fine dust suspended in its thin air scatters sunlight so that the blue gathers into a halo around the setting sun while the rest of the sky stays yellow and orange, leaving the planet that looks rusty all day to end it with a cool blue glow.

The Andromeda galaxy is the most distant thing you can see with the naked eye, and the light reaching your eyes from it tonight left some 2.5 million years ago, long before our own species existed.

Tom Mueller spent nearly two decades building the Merlin and Draco engines that helped make SpaceX possible, and now his in-space mobility company has crossed $1 billion in venture funding before its fastest vehicle has flown to geostationary orbit

3I/ATLAS is only the third confirmed interstellar object ever detected passing through our solar system. It may be older than the Sun itself, and Webb observations show it is carrying an unusually carbon dioxide-rich coma as it swings past once before leaving for interstellar space forever.

Earth quietly picks up tiny second moons from time to time, small asteroids briefly caught by our gravity before they wander off again, which means our planet has carried far more moons than the single one most people ever notice.

The first humans on Mars will not just be explorers crossing a red desert. They will be radiation workers, dust-control technicians and weather-watchers on a planet where the danger is less dramatic than constant.

The James Webb telescope keeps finding early galaxies that look brighter, bigger and more mature than astronomers expected, forcing researchers to rethink how quickly the first galaxies formed stars and assembled after the Big Bang.

In 1959, the Soviet Luna 3 probe swung around the far side of the Moon and took 29 grainy photographs of a hemisphere humans had never seen, then developed the film onboard and scanned the negatives with a flying-spot beam to radio them back across nearly 480,000 kilometres of vacuum

There are millions of objects in our own solar system that have never been seen and the facility that will find them is now just months from starting its decade-long survey

Parker Solar Probe has flown through the Sun’s outer atmosphere, the corona, where temperatures soar into the millions of degrees even though the visible surface below is far cooler — one of the strangest long-running puzzles in solar physics.
