Two spacecraft – one built by India and the other by Russia – are hurtling on missions towards our Moon by very different routes. Does it matter which will win?

A UCLA-led study of NASA’s DART mission determined that the strategy presents previously unanticipated risks.

A daily update by email. Science news, great photos, sky alerts.

A stealthy asteroid the size of a 20-story building hid in the sun's glare before zooming uncomfortably close to Earth on July 13. Scientists didn't notice until July 15.

With Chandrayaan-3, India aims to be the first to land near the Moon's little-explored south pole.

An astrophysicist at Harvard University believes he may have found proof of extraterrestrial life not by studying the vast night sky, but by combing the bottom of the Pacific Ocean. Last month, a crew aboard a boat called the Silver Star embarked on an expedition to Papua New Guinea with the mission of recovering fragments from a mysterious meteor that had crashed into Earth in 2014.

Space propulsion company Pulsar Fusion has started construction on a large nuclear fusion chamber in England, as it races to become the first firm to fire a nuclear fusion-powered propulsion system in space. Nuclear fusion propulsion tech, arguably a golden goose of the space industry, could reduce the travel time to Mars by half and cut the travel time to Titan, Saturn’s moon, to two years instead of 10. It sounds like science fiction, but Pulsar CEO Richard Dinan told TechCrunch in a recent interview that fusion propulsion was “inevitable.”

"Sandwiched planet formation" may arise as the result of gas and dust being squeezed between large planets.

A new space observatory is flying across the void after a dramatic launch atop a SpaceX rocket Saturday (July 1), but its journey has just begun. The European Euclid space telescoe began its long journey to deep space on a SpaceX Falcon 9 rocket at 11:11 a.m. EDT (1511 GMT) from Cape Canaveral Space Force Station on Florida's Space Coast.

"We're starting to open up this new window on the universe," one astrophysicist said.

A new study of astronaut blood finds that space travel reduces the expression of 100 genes related to the immune system.

Until JWST’s sharp infrared eyes came along, it wasn’t possible to see the galaxies hosting extremely bright supermassive black holes called quasars.

How large would an extraterrestrial city have to be for current telescopes to see it? Would it need to be a planet-sized metropolis like Star Wars' Coruscant? Or could we see an alien equivalent of Earth's own largest urban areas, like New York City or Tokyo?

A planetary system is shaped at the boundary of order and chaos. It starts out as a molecular cloud—a big, cold clump of mostly hydrogen gas that can collapse to make stars. As central stars form, the remainder of the cloud flattens into a whirling protoplanetary disk that weaves together worlds from turbulent swirls of gas, ice and dust. From there larger-scale chaos can ensue as bigger planets push smaller ones around.

The theory could have important implications for the search for life outside the solar system.

The bright, red star Betelgeuse in the constellation Orion has shown some unexpected behaviour.

Resources that are finite on our planet "are abundant in the universe," AstroForge CEO Matt Gialich told IE in an interview.

NASA researchers say Moon astronauts should consider that microbial life could survive in shadowed niches near the south pole.

NASA wants more than just a lunar golf cart.

Cocoons of debris around dying stars could shake ripples in spacetime unlike any astronomers have ever seen. “This is a potential source of gravitational waves that has never been investigated before,” astrophysicist Ore Gottlieb of Northwestern University in Evanston, Ill., said June 5 in a news conference at the American Astronomical Society meeting in Albuquerque.
