The mission is set to launch in March 2022. Here’s what you need to know.
Only a planet crashing into it might stop the Earth’s spin.
We may be on the brink of discovering whether water and organic material, which enabled life on Earth, came from asteroids.
Life doesn’t just need water and oxygen to thrive, it also needs iron.
Most of what we know about planets outside our Solar System relates to gas-giant planets. A new study has identified and characterised a smaller exoplanet.
Welcome to an entirely new understanding of the world.
Photographing the full Earth from space could provide a profound and timely reminder of its vulnerability in the face of climate change.
Without a magnetic field, the Moon’s surface is exposed to solar wind. These could have been depositing resources like water and potential rocket fuel on the Moon’s surface for billions of years.
When heat in doesn’t equal heat out, Earth sees changes.
The Earth is constantly changing in natural ways, but most of those changes are very slow. Humans are speeding up other changes with global warming.
Gravity is something every person on Earth intuitively understands: It is what keeps you on the ground. But how come gravity pulls down, rather than pushes up? Einstein came up with the answer.
Astronomers know a lot about what’s in outer space – and think it’s possible it never ends.
This Wednesday night, everywhere in Australia will have a box seat for a spectacular total eclipse of the Moon.
In the early morning of May 26, 2021, there will be a super blood-red lunar eclipse. The show will be spectacular and can all be explained by the orbits of the Earth and Moon.
The snail’s pace of action in this year’s federal budget on climate is out of step with the urgency of the climate and income inequality crises.
To combat the biodiversity crisis, we need to fundamentally shift our economy and society and make nature conservation the norm.
A young reader asks: What is the sky?
The rocks provide rare evidence of a time when Earth’s surface was a deep sea of incandescent magma.
A minuscule particle of asteroid dust has helped reveal how celestial rocks like Earth might have sprouted life.
