If you got too close to a black hole, it would suck you in and you'd never be able to escape, even if you were travelling at the speed of light.
This point of no return is called the event horizon.
A 100-metre-wide asteroid passed just 70,000km from Earth on Thursday, and we had little warning it was about to happen. What threat is posed by asteroids and how do we find them?
As more than a million people have indicated plans to partake in a citizen 'raid' on the famed Area 51 to 'see them aliens,' a scholar on the search for extraterrestrial life weighs in on the hype.
The short answer is yes, but it’s really, really difficult.
The first humans to land on the Moon, and the team that got them there, get all the glory. But what about the people who laid the foundation for this effort by mapping the Moon? Who were they?
On the 50th anniversary of man's historic moon landing, Pedro Duque remembers how every child wanted to be an astronaut in 1969.
Scientists spend years preparing for the two-minute window of a total solar eclipse.
For the first time scientists have located the home galaxy of a one-off fast radio burst. Here's how they did it – and what they learned about the galaxy.
A new podcast series from The Conversation exploring the last 50 years of space exploration and the 50 years to come.
It is always exciting to discover new planets beyond our Solar System. Now a planetary astrophysicist is using a star's chemistry to predict which ones are likely to host giant planets.
Astronomers have found the first observational evidence for a disc of material around a giant young planet at a distant star. It's a place they think moons can form.
Every day about 50 tons of rocks from space fall on Earth. An examination of these meteorites has inspired a new theory about how exactly these rocks formed.
The first 60 satellites from Elon Musk's planned low orbit internet network have lit up the skies. But with more planned, astronomers say the satellites could ruin their work.
The signal came in on ANZAC Day, ripples in space-time from the merger of two neutron stars an estimated 500-million light years away. But where it happened is still a mystery.
Science is full of surprises. While searching for planets orbiting nearby stars, researchers stumbled across the remains of a star that once outshone the Sun.
A spinning black hole is pumping vast amounts of energy back into the surrounding universe, but something is causing the jets that transport that energy to wobble very rapidly.
The far side of the Moon sees its share of sunlight – it's dark only in the sense that it's mysterious because it's never visible from Earth. Here's why.
By studying old and dead stars, we can discover what will happen to our sun in the far, far future. And it won't end with a big explosion.
Astronomers say they have "seen what we thought was unseeable" in releasing the first image of a supermassive black hole. So how did we get to this historic observation?
