$23 million is a big price tag for a toilet even if that figure covers two units, one for the International Space Station and one for a future Moon mission.
Salyut 7 fell silent in February 1985, tumbling and frozen. Four months later Soyuz T-13's crew docked with the dead station by hand and nursed it back to life, one of the hardest repairs ever done in orbit.
The windiest world we know of runs on almost no sunlight. Voyager 2 clocked its storms at supersonic speed during a single 1989 flyby, and scientists still cannot fully explain what powers them.
It is the first of an estimated 10,000 stellar-mass black holes thought to hide in the cluster, and the only one whose orbit has ever been traced. The catch is that the orbit is unfinished: the 94-year period rests on a partial arc, caught while the star was swinging fast past its dark partner.
A war fought in orbit will not stay between the two countries that start it. That was the blunt message Gen.
In the last hour of the final Apollo mission, Gene Cernan traced his daughter Tracy's initials into the lunar dust — and on a world without weather, they may still be legible millions of years from now.
A tank of ultrapure water a kilometer under a Japanese mountain has turned up the first statistical sign of the diffuse supernova neutrino background. It is a 2.6 sigma indication, not the confirmed detection physics still wants.
The first X-ray ever taken of a human body, in 1895, was of Wilhelm Röntgen's wife's hand, wedding ring and all.
Saturn's largest moon runs a full hydrological cycle — clouds, storms, rivers, lakes, seas — but the rain is liquid methane and the bedrock is water ice frozen to about minus 179 Celsius, hard enough to build mountains from.
SpaceX is targeting Thursday for the 13th full-scale test flight of Starship, a mission that will carry Starlink satellites into a suborbital trajectory and…
In South Korea's 2015 census, one in five people was named Kim: 21.5 percent of the population, or 10.69 million people.
In February 1966, the Soviet Luna 9 probe bounced across the Ocean of Storms and unfolded four petal antennas — and Britain's Jodrell Bank observatory intercepted its picture signal, recognised the newspaper-fax format, and published the first photograph from the Moon's surface before Moscow could.
Four or five raw red kidney beans carry enough phytohaemagglutinin to hospitalise a healthy adult within hours. A 2018 outbreak in Brittany showed exactly what happens when the cooking temperature stays below a full boil.
Twice a month, at new and full moon, the Sun and Moon align with Earth and their tidal pulls stack together — producing spring tides that are simply solar system geometry printed on a weekly tide table.
In July 2026, a research team led by Alessio Terzi, an assistant professor at Cambridge's Bennett School of Public Policy, and Francesco Nicoli of the…
The Moon looks frozen in time, its craters preserving impacts billions of years old.
