The truth is we don’t really know if space goes on forever – but maybe, one day, we will find out.
People used to think that when they looked up at the night sky, they were seeing all of space. Then American astronomer Edwin Hubble found out something so amazing, NASA named a telescope after him.
Saturn and its rings backlit by the sun, which is blocked by the planet in this view. Encircling the planet and inner rings is the much more extended E-ring.

Australia's hoping to take a share of the billion-dollar space industry with the launch of its first totally Australian-built satellites in 15 years.
In conversation: Martin Rees.
The Astronomer Royal answers some of the world's – and the universe's – biggest questions.
Co-working can be a refreshing change for many employees where the design of the workplace and the politics of their organisation means they are simply too tired.
Co-working spaces are evolving to suits the needs of a changing workforce.

Astronomers are surprised by what they're finding out about galaxies that formed in the early days of our universe, now that sensitive telescopes allow direct observation, not the inference of old.
In the face of recent political events in Britain and America, sci-fi imaginings of the 'citizens of the future' have taken on a new resonance.
Most modern spiral galaxies, such as NGC 1300, are thought to have loads of dark matter in their outer regions.

So where did all the dark matter come from?
Look ma, no gravity!
Every moment of life on our planet has had the force of gravity in the background. But the prospect of long-distance space travel means it's time to figure out what happens to our biology in its absence.

The Earth's magnetic field acts like a giant instrument playing magnetic music.
Hidden Figures is certainly inspirational, but the racial politics of the space programme were hardly so easily settled.
Space exploration and exploitation has changed a lot in 50 years.
The Outer Space Treaty, now 50 years old, has so far never been violated. But things could be about to change.
Tiny CubeSats are ready to be our eyes in the skies.

Often eclipsed by Apollo 11, the final manned moonshot left far more than bootprints in the dust. In these troubling times, it also left us with a lasting message of hope.
The discovery of the year was the first detection of gravitational waves.
Colliding black holes to exploding spacecraft, 2016 was an incredible year for astrophysics.
Listen to some weird space sounds and help identify crunches, whistles and other odd effects. It could help save our satellites.
Using terrestrial forensic science to point the finger of blame to criminals in space will be much harder than it looks.
Leibniz’s 'great question' remains a central question in philosophy and science today.
Enjoy the full moon’s glow.
Full moons are good reason to look up – and the one on Nov. 14 is no exception. But here’s why you likely won’t see something shockingly different from other full moons you've observed over the years.
