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.
Proponents of mining in space often point to the potential benefits for Earth and its people. But this research casts doubt on many of them.
Discovered less than a week ago, the truck-sized asteroid skimmed much closer to Earth’s surface than most satellites.
The UK space launch failed but it succeeded in releasing hazardous pollutants to multiple layers of the atmosphere.
Nothing is harder to find than you might think.
NASA has been gaining momentum in recent years as investment into space has ramped up in the US. In 2022, missions dealt with the farthest, closest, hottest and coldest conditions in the universe.
Gamma-ray bursts occur when a massive star explodes or when two neutron stars merge. A newly discovered burst has puzzled astronomers, as it lasted much longer than astronomers would have expected.
Astrology and astronomy were once practiced side by side by scientists like Galileo and Kepler. And they’re more similar than you might think.
Canadian space technologies and innovations play a significant role in the Artemis missions, and our involvement reflects our growing role in this new era of lunar exploration.
China has completed construction of the Tiangong space station, and science projects are now underway. The station is an important piece of China’s ambitious plans for space activity in coming years.
A new photo taken on the Artemis I mission shows Earth isn’t a sealed spaceship, but is in dynamic interchange with the cosmos.
Blue Marble is the last photograph of the whole Earth taken by an actual human using analogue film: developed in a darkroom when the crew returned to Earth.
Spacecraft are just a small part of what it takes for humans to become an interplanetary species. A political science professor explains how there is much more to creating a spacefaring society.
