Houston company Axiom Space's next astronaut launch to the International Space Station, a mission called Ax-4, has been pushed back by 10 days, to June 8.

NASA’s astrobiology ambitions are at risk of collapsing under the White House’s proposed budget. But your voice can make a difference

The Canon EOS R5 Mark II is a high-end professional camera packed with the latest technology and designed to capture any subject you can throw at it.

NASA's Perseverance Mars rover made skywatching history in March, becoming the first robot to witness auroras from the surface of another planet.

We're less than two months away from Superman's return to cinemas, and the latest trailer for James Gunn's reboot is colorful, punchy, and hopeful.

Technology has made it easier than ever to quickly find, identify and record birds. But to truly appreciate feathered friends, consider unplugging

We now have full genome sequences for six species of apes, helping us to pin down our last common ancestor – and potentially changing how we think of the earliest hominins

Newborn pilot whales have been spotted mysteriously swimming among pods of orcas. Scientists are trying to puzzle out how the pilot whale calves got there and what happened to them

New research helps the “ocean’s veins” thrive under heat stress

In spite of policies requiring housing projects in England to benefit nature, many of the trees, habitats and nest boxes included in planning applications haven't materialised

NASA's new PUNCH spacecraft captured colorful images of the zodiacal light while testing out their sun-watching instruments.

Just as ice dominates the outer Solar System, blanketing the moons of giant planets and coating objects in the Kuiper Belt and Oort Cloud—astronomers using the James Webb Space Telescope have made a chilly discovery in a distant planetary system. The alien system HD 181327, 155 light-years away harbours significant deposits of both ordinary and crystalline water ice. They detected the ice in regions that are farther away from the star, with the outer area containing as much as 20% water ice.

New calculations suggest that the universe's most enduring celestial objects, such as white dwarf stars, are decaying faster than previously thought.

One of the big differences between Venus and Earth is the lack of plate tectonics. While Earth's continents float on tectonic plates—constantly reshaping our world—Venus was previously thought to remain locked in a largely static crust with only occasional volcanic hotspots. But everything we thought we knew might be wrong! Researchers examining 30-year-old NASA Magellan spacecraft images have spotted what appears to be the smoking gun of tectonic activity on our hellish sister planet, potentially rewriting planetary science as we know it.
