CubeSats upon release from the International Space Station.
Just about anyone can get a tiny, cheap satellite into orbit these days. As we consider how to deploy them responsibly, inspiration comes from an amateur community of enthusiasts.
Four identical NASA spacecraft fly near the sun-facing boundary of Earth’s magnetic field (the blue wavy lines).
After half a century of trying, scientists have finally caught a glimpse of the magnetic process that fuels space weather and the northern lights.
kepler all planets may.
The increasingly rapid pace of exoplanet discoveries must mean it is only a matter of time until astronomers find another Earth.
We’re on the hunt for life – what do we do when we find it?
A philosopher argues that now is the time to figure it out, before we make the inevitable discovery of extraterrestrial life.
Why weightlessness in space is about balancing forces rather than a lack of gravity.
The plan to use lasers to send mini-spaceships to the stars.
It's an ambitious plan to send a micro-spaceship to our stellar neighbour but is this possible with today's technology or even technology in the near future?
Are we soon to visit Alpha Centauri (left)?
Building a tiny starship may be doable. The big challenge will be making sure it survives all the hazards in interstellar space.
SpaceX’s Falcon 9 rocket blasts off.
Yes, it really is rocket science.
Gene Cernan driving a lunar rover in December 1972.
The Last Man on the Moon is much more than a biographical documentary – it is a gripping account of human endeavour.
What are you thinking? Robots and humans working together need to understand – and even trust – each other.
People and machines need to be able to interact and communicate effectively. Right now we – and they – can't. But without that, we risk missing the potential benefits of collaboration.
New Horizons continues to help unravel the icy dwarf planet’s secrets.
NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute
After last summer's Pluto flyby, the New Horizons spacecraft started sending data back to Earth – at 2 kilobits per second. Here's some of what scientists have learned so far from that rich, slow cache.
The only way to fly the friendly skies – or dark voids of space.
We're on the cusp of being able to consistently launch and land rockets, greatly reducing the cost of space travel. But how long before there's a Millennium Falcon in every garage?
Walk on the wild side.
Scott Kelly's year in space is over. Now we need to know what it did to his body.
Out of this world.
We already have much of the technology we’d need to start a colony on another planet.
How would people react to mining on the moon?
No one nation should be allowed to go it alone and develop a mining industry in space. It needs an international effort and Australia, with a long history in mining, can play its part.
Don’t get too close.
The spectacular science of quasars, no hair theorum and spaghettification.
The 50th anniversary of Luna 9's first soft moon landing reminds us how difficult landing a spacecraft is.
Tragedy: Challenger exploded shortly after launch from the Kennedy Space Centre.
We should honour the dead by striving to go further.
No warp drives or worm holes required.
Nice night for a stroll: Scott Kelly working outside the International Space Station in 2015.
What's life like in a hostile environment that's literally out of this world?
