Astronomers are hot on the search for new exoplanets – planets that lie beyond our Solar System – which might show potential for sustaining life.
China has invested massively in its space capabilities in recent years and is now a major competitor with the US. But according to a space policy expert, the US still dominates space by most measures.
The Jupiter Icy Moons Explorer and Europa Clipper missions will arrive at Jupiter in the 2030s and provide researchers with unprecedented access to the icy moons orbiting the gas giant.
The Artemis II mission is scheduled for launch in late 2024 and is a critical step towards NASA’s goals of establishing a permanent human presence on and near the Moon.
Canadian Jeremy Hansen will be one of the next astronauts on the Artemis II mission. This announcement signals a new era in Canada’s role in space exploration.
Rockets used to launch satellites fall back to Earth, and as their number grows, the risk faced by people living on the ground — or flying in airplanes — increases.
A US-led coalition and China are both planning to establish bases on the Moon. How the two nations will navigate actions on the Moon and how other countries will be involved is still unclear.
The discovery of a key component of RNA in samples from asteroid Ryugu adds weight to the theory that basic organic molecules may have arrived on Earth from outer space.
Astronomers have long known where water is first formed in the universe and how it ends up on planets, asteroids and comets. A recent discovery has finally answered what happens in between.
With more than 5,000 known exoplanets, astronomers are shifting their focus from discovering additional distant worlds to identifying which are good candidates for further study.
Five new studies show smashing spacecraft into asteroids could be a viable way to defend Earth from threatening space rocks.
Astronomers have found that mysterious dark energy may originate in black holes.
There are thousands of sightings of UFOs – or ‘unidentified aerial phenomena’ as the US government prefers to call them – every year.
The Solar System as we know it doesn’t really make sense without a ninth planet. So then why can’t we find it?
An elaborate scheme to shade Earth with millions of tonnes of Moon dust floating in space is unlikely to get off the ground.
With more than 100 lunar missions planned in coming years, space junk near the Moon could become an issue for humanity. No agency tracks lunar space junk, so two astronomers decided to do it themselves.
Efforts to launch rockets into space from the UK need to demonstrate reliability.
Can artificial intelligence transform the search for alien intelligence?
A new image has been taken of the whole Earth 50 years after the first - revealing noticeable changes to its surface.
