Cosmonaut Sergey Prokopyev went for a ride on a robotic arm outside the International Space Station after outfitting it with a work platform.

We can’t bring humanity’s closest relatives back to life, but this could be the nearest thing.

The oscillation was found while scientists were studying the properties of superconductors.

The invention of the printing press revolutionized duplication of the written word, giving the hands of tired scribes a break and making written material more accessible. A similar breakthrough has happened in reverse in the McKelvey School of Engineering at …

On Aug. 12, 2023, NASA’s STEREO-A spacecraft will pass between the Sun and Earth, marking the first Earth flyby of the nearly 17-year-old mission.

Virgin Galactic just flew its first tourist crew, and SpaceX has launched a few. Researchers say space-tourism companies should have the sex talk.

An extreme star system is giving new meaning to the phrase "surf's up."

While their damage is unsightly, many caterpillar species that emerge in late summer to munch on leaves are generally not a major threat to tree health.

Watch an incredible timelapse video showing 17 years of an exoplanet 12 times more massive than Jupiter orbiting its host star just over 60 light-years from Earth.

The world's highest mountain system may have reached 60% of its current elevation before the Indian and Eurasian tectonic plates crashed into each other, giving the peaks an extra push.

Tides on the star MACHO 80.7443.1718 are so extreme that they crash and break every close passage in the pair of stars’ elliptical orbit. Models show how these breaking tidal waves create a rapidly rotating, shock-heated circumstellar atmosphere every periaps…

Paleontologists working in northern Alaska have discovered a tiny fossil mammal that thrived in what may have been among the coldest conditions on Earth about 73 million years ago.

The fossilized eggs of five different parasites were ID'ed in a 2.91-inch-long poo fossil. The poo fossils had been 'repurposed as talismans' by 'intrigued' villagers, one scientist said

The ocean’s hydrothermal vents are like hell on Earth—pitch black volcanic fissures with temperatures as high as 700 degrees Fahrenheit. For decades, scientists have been aware of the strange…

“If there is a Garden of Eden, it is Africa.”

The Russian space agency had previously threatened to withhold access to Europe's robotic arm at the height of geopolitical tensions last year.

A scientist has observed a "gravitational anomaly" in certain star systems that could potentially upend a fundamental assumption about the universe, according to a new study. Motherboard reports: Kyu-Hyun Chae, an astronomer at Sejong University, has now put…

The four astronauts assigned to fly around the moon next year have gotten their first look at their spacecraft.

Researchers have observed "quantum superchemistry,” when a chemical reaction occurs among a collection of particles that are all in the same quantum state.

If it were up to NASA administrator Bill Nelson, the US needs to get to the Moon before China since it might be unwilling to share resources.

The most intense space weather event of the past two decades hit GPS satellites' orbit just after a solar minimum.

Genetic kinship analyses of human bones reach their limits if the DNA is poorly preserved or if destructive sampling is not possible. New research shows that in such cases, comparisons of the structure and shape of certain parts of the skeleton may also provi…
