Germany's Isar and RFA, France's Maiaspace, Spain's PLD Space, and UK-based Orbex have been pre-selected for ESA's €169 million launcher initiative.

Acknowledging the limits of one’s own knowledge could be as important a signal of expertise as credentials and confidence

"There's some great targets in the southern hemisphere, including the Carina Nebula."

The rise of AI-generated content since 2022 risks making it impossible to know when information was produced solely by humans, which could be a problem for both future AI and historians

Astronauts aboard the International Space Station collect blood samples as part of a project to study human health in space.

A computer simulation of stars near the centre of our galaxy offers an explanation for their mysteriously young appearance – they may be capturing dark matter for extra fuel

The Langlands program has inspired and befuddled mathematicians for more than 50 years. A major advance has now opened up new worlds for them to explore

Astronomers have discovered a baby exoplanet "spiral architect" carving complex swirls into a disk of gas and dust around the young star HD 135344B.

This episode of Science Quickly goes on an archival adventure in Scientific American’s July 1925 issue.

Our planet has been rotating at its fastest since records began in 1973.

 

The most complex parachute system to ever deploy on Mars has successfully slowed down an ExoMars mock-up landing platform for a safe touchdown on Earth.

What is going on with this galaxy?

South Korea just laid out its long-term space exploration road map, which features the planned construction of a moon base two decades from now.

Scientists have grown algae in bioplastic habitats under Mars-like conditions, a step that could bring long-term space colonization closer to reality.

Find the locations of the five landing zones considered as the setting for humanity's first steps on another world.

Macquarie University astronomers have tracked an extreme planet's orbital decay, confirming it is spiraling toward its star in a cosmic death dance that could end in three possible ways. It could cross the Roche line and be torn apart, it could plunge to destruction in its star, or it could be stripped all the way down to a rocky core.

Atmospheric escape shapes an exoplanet's future. Earth's exosphere is extended and detectable due to ocean-related atmospheric escape. If we can detect the same features on an exoplanet, it could suggest oceans and habitability. But we need to build the Habitable Worlds Observatory first.

Trans-Neptunian Objects reside in the distant Solar System as remnants of the System's early days. They follow unusual orbits and range in colour from reds to greys. New research uses their colours and orbits to show how a stellar flyby can account for their modern-day orbits.
