Space mining has the potential to provide a greater supply of resources either for being exploited locally for construction or being sent back to earth.
A new name on a few military badges doesn’t imply an escalating arms race.
Those who speak of the inevitability of war in space will fuel a race to the bottom, and see even more energy towards an arms race in space.
The blood moon myths are many and varied, but, at the end of the day, it’s just an eclipse.
Jeff Bezos plans to charge US$200,000-300,000 for a trip to outer space. And it’s going to cost him an astronomical amount of money.
The pull created by a black hole is so strong that if you get too close to one – even if you are travelling away from it at the fastest speed it is possible to go – you will never be able escape.
A wormhole is like a tunnel connecting two places in space. They would be incredibly useful and are great for science-fiction stories.
The problem is we haven’t found any evidence of them existing.
An astronomer suggests an idea to piggyback on the ambitious Breakthrough Starshot project that aims to send nano spacecraft to Alpha Centauri at a major fraction of the speed of light.
Trunp’s new policy could lead to the militarisation of outer space and the beginning of a new space arms race.
To answer this tricky question, we have to look back in time to when the Earth was born, 4.5 billion years ago.
Will new communications licensing costs make small satellites so expensive that they can’t be used for student education?
Pretty much as soon as we understood what galaxies were, we realised they are all moving away from each other. And the ones that are further away are moving faster. In short, the universe is expanding.
With a little bit of knowledge and a few pieces of equipment you too can look at the night sky and see it as a cosmologist does.
It would be a heavy lift, but revising the Iran nuclear deal would have some significant upsides, according to scholars at the University of Maryland.
New jobs and investment for Australia’s growing space industry are promised with the backing of the new space agency. It’s hoped that all states and territories will benefit from a national approach.
Astronomers are gathering an exponentially greater amount of data every day – so much that it will take years to uncover all the hidden signals buried in the archives.
Out there in space there is no air. If you took your helmet off, all the air you need to breathe would whoosh out.
How long before we find a planet just like our own?
When NASA first started planning the Kepler mission, no one knew if the universe held any planets outside our solar system. Thousands of exoplanets later, the search enters a new phase as Kepler retires.
