Sixty years ago, philosopher Hannah Arendt argued an interplanetary perspective may be bad news for humanity as we know it.
Sound needs matter to propagate, so the vast vacuum of space is not just empty − it’s silent.
A newly discovered planet that should be too big to have formed around a tiny star is throwing into question what researchers know about planet formation.
Five of the Uranus moons might be ocean worlds − and if there’s water, there might be life.
Borman’s professionalism helped the risky Apollo 8 mission become a success.
The universe is expanding faster than physicists would expect. To figure out what processes underlie this fast expansion rate, some researchers are first trying to rule out what processes can’t.
Some dark craters on the Moon are never exposed to light − ice could be hiding in these permanently shadowed regions, and India’s Chandrayaan-3 mission marked a big step toward finding it.
In September 2023, a NASA mission successfully brought samples of an asteroid down to Earth in a sealed capsule. Analysis of these samples may reveal information about the origins of the universe.
When you’re an astronaut landing on the Moon, you can’t rely on the same gravitational cues we have on Earth. But regimented training with sensory devices could one day prevent spatial disorientation.
Viral headlines would have you think Saturn’s rings will vanish in just 18 months. Here’s what that really means and why you don’t need to worry.
Despite the distances involved, people as far apart as the UK and Australia can see the Moon at the same time.
For All Mankind is set in an Apollo era transformed by the inclusion of women, characters of colour and LGBTQ+ protagonists.
Space junk and carbon emissions are just some of the problems with a boom in space travel.
Upcoming NASA missions will help scientists understand the composition of asteroids – which could inform companies one day hoping to commercially mine asteroids.
Scientists have been searching Earth’s surface for superheavy elements too difficult to make in the lab, but now, many are looking to the skies instead.
A more active Sun could disable satellites and affect electrical grids on Earth.
Some space rocks you can get for free – if you know how to identify them. Rarer materials cost more, and the asteroid sample NASA just brought back has a high price tag.
The meteor shower happens when Earth passes through debris from Halley’s comet.
The atmosphere is a reflection of extreme conditions on the super-heated planet.
