The scariest beast in the universe has an insatiable appetite and shreds its victims.
Researchers have long suspected there’s water - or ice, to be precise - on the Moon. New research now confirms it, and suggests it lurks in sun-starved nooks and crannies called ‘cold traps’.
OSIRIS-REx will touch down on asteroid Bennu, collect a sample of the dust and begin its journey back to Earth, where scientists will study it, hoping to learn secrets of the solar system’s origin.
Surprising findings on an exquisite and huge star system in our Milky Way suggest future potential for an extremely rare gamma-ray burst. This event has never been observed in our galaxy.
The 2020 Nobel Prize in physics was awarded to three scientists – an Englishman, an American and a German – for breakthroughs in understanding the most mysterious objects in the universe: black holes.
News that Venus may harbor life has swept the globe. So how do we find out for sure? A planetary scientist explains what’s next.
There is a reason why it’s easier to roll marbles down rather than up a hill. And the answer (to this and to gravity itself) is all about acceleration.
This summer, NASA’s Mars Perseverance rover is taking the next giant leap in our search for signs of life beyond Earth.
Are you hesitating to buy anti-Covid-19 toothpaste? 100 years ago, you might have found some miracle elixirs to protect you from Halley’s Comet.
Duckweed is the perfect space food: small, fast-growing and nutritious. By studying how light levels changed the production of radiation-fighting antioxidants, researchers made it even better.
A new country launches a mission to Mars. A space expert explains what this means for the Middle East and the African continent.
Why are scientists trying to grow organs at the International Space Station? People live on Earth not in zero-gravity. A stem cell expert explains why it is useful to do these experiments in space.
Australia’s space industry is booming despite the impact of coronavirus.
If gravity was half as strong, you could jump much higher.
How do people in a special airplane flight get to float like there is no gravity – just like astronauts? An aerospace engineer explains.
Martian meteorites allow scientists here on Earth to decode that planet’s geology, more than a decade before the first missions are scheduled to bring rocks back home from Mars.
Women are in many ways ideal astronauts, but the world of space has been designed for men.
When it comes to commercial space tourism, suborbital flight are the first frontier. But what are the risks? Are there health requirements? What should you know before taking such a way-out trip?
The distance between the ISS and Earth is the same as about 3,850 football fields. To bring the station down, rockets will lower it a bit, and then gravity will send it crashing the rest of the way.
