Astronomers have found a true colossus of a jet in the night sky, over 100 times larger than our galaxy. It’s almost perfectly straight, which presents a puzzle.
Boeing Starliner took the astronauts to the International Space Station – but NASA doesn’t think it’s safe for the return trip. What happens next?
If a star gets too close to a black hole, it gets shredded and produces a complex ball of light. These videos are the first time this dramatic event has been simulated in detail.
NASA’s enduring NEOWISE mission was just shut down. It was keeping an eye out for potentially dangerous asteroids – but we’re not left defenceless.
NASA’s DART was the first time we tried planetary defence – attempting to redirect an asteroid. The data from this landmark mission is still yielding new insights today.
Vast amounts of space rocks litter our Solar System, and sometimes land on Earth’s surface. There are many things we can learn from them.
Astronomers and stargazers around the world are excited to witness a rare event that only happens once every 80 years – a recurrent nova.
An interstellar probe could help scientists answer fundamental questions about how the Sun influences Earth, space and other planets in the solar system.
When rocks from space fall towards Earth, they usually don’t do any damage – here’s why.
China’s Change'6 is going to explore the Moon’s far side and bring back precious lunar soil for scientists to study.
The Eta Aquariid meteor shower peaks each year in early May, but this year it should be particularly good, thanks to dark skies and extra activity.
When astronomers focused on the galaxy NGC 4383, they didn’t expect the data to be so spectacular. This is the first detailed map of gas flowing from this galaxy as stars burst within.
If you look carefully at the night sky, you may spot this fuzzy visitor with the naked eye – but binoculars will help.
Japan’s space agency is landing its first lunar probe this week. This makes the Moon an increasingly busy target for spacefaring nations – with conflicting political stances among them.
A telescope can reveal so much of the night sky, including Saturn’s rings and the Moon’s craters. But choosing the right telescope is a difficult decision – here’s what you need to know.
People have been looking up at the stars for thousands of years. Here’s where to start if you want to learn more about the night sky – from spotting easy-to-find constellations to using the best apps.
Despite what you may think, Australia has a long history of space activities. But this is the first time the Australian public has been asked its opinions on space.
Planetary analogues are sites on Earth that are so extreme that they replicate those of celestial bodies in our solar system.
Black holes are known for pulling in all kinds of stuff – including light. Here’s how that actually works.
