A large near-Earth asteroid will pass within a historically close distance this June, giving astronomers a rare opportunity to study its structure and motion.

ESA astronaut John McFall tells Live Science what it would mean to become the first physically disabled person in space — if he travels to the first-ever commercial space station next year — and how life in orbit might affect him differently than everyone else.

The crescent moon will shine alongside Jupiter, Venus and Mercury as it passes through the Beehive open star cluster on June 17.

A blurry photo captured by the Green Bank Telescope in West Virginia shows Artemis II's Orion capsule circling the moon more than 200,000 miles away, making it a candidate for the longest-distance image of humans ever taken from Earth.

Elon Musk became the world's first trillionaire shortly after SpaceX debuted on the Nasdaq.

Even at this early stage in our space faring age, humanity has already begun sending probes that will eventually reach other solar systems, even if that was not their original intention. Five robotic explorers - Pioneer 10 and 11, Voyager 1 and 2, and New Horizons - are all on escape velocities out of the solar system, and might someday enter another one. They will no longer be operational at tha…

SpaceX's valuation has increased by $1 trillion since its shares started trading on Friday.

A video of the Aurora Australis (Southern Lights) was captured from the SpaceX capsule Dragon.

New observations reveal unexpected atmospheric patterns on the Sun hours before an X9-class solar flare, hinting at possible early warning signals for space weather prediction.

On June 16, 1963, 26-year-old Soviet cosmonaut Valentina Tereshkova made history by becoming the first woman to travel into space. A former factory seamstress, Tereshkova was an accomplished amateur parachutist with over 100 jumps — a vital skill, since Vostok cosmonauts ejected before landing. Selected from over 400 applicants in 1962, she underwent months of Continue reading "June 16, 1963: Val…

An artistic representation of WASP-94A b, a gas giant in the Microscopium constellation, shows how clouds build on the dark side of the planet and are blown to the dayside, where they dissipate. This leaves the morning edge of the planet, where the winds move from nightside to dayside, permanently overcast. Credit: Hannah Robbins/Johns Hopkins University

A seemingly ordinary photo of Earth taken during Artemis II is hiding several remarkable features. Most viewers won't notice them immediately, but once spotted, they completely change the way the image is seen.

A major challenge to dark energy, the mysterious force believed to be driving the universe’s accelerating expansion, has been overturned by a new study. Astronomers say a new analysis has reinforced one of the most important discoveries in modern cosmology, finding that the universe is still expanding at an accelerating rate. The result counters a [...]

James Webb has revealed that the sunrise and sunset sides of WASP-121 b have surprisingly different atmospheres. Astronomers using the James Webb Space Telescope (JWST) have discovered striking differences between the morning and evening sides of the atmosphere of WASP-121 b, an ultra-hot gas giant located far beyond our solar system. The findings provide the [...]

A team of astronomers has found strong evidence that a star similar to our sun may have eaten one of its own planets. The star, known as TOI-5882, is located about 1,300 light-years from Earth. Researchers discovered that it contains an unusually high amount of lithium, a chemical element that may reveal a dramatic event […] The post Astronomers discover Sun-like star that likely swallowed one of…
