Textbooks often show Earth’s orbit around the Sun as an almost egg-shaped ellipse. The real story is very different.
Analysis of fragments of the first solids that emerged out of the birth of the sun date our supernova as being 4.6 billion years old.
The Solar System could be awash with oceans, not on the surface but hidden inside the most surprising bodies
The largest study yet of ‘twin stars’ shows planetary orbits may be less stable than we thought.
Mars has been a popular destination since space exploration began – and there are plenty of people who’d love to go there.
You might hate winter, but at least you know what to expect every year. Other planets have wobbly axes that lead to wild, unpredictable seasons.
It turns out Uranus actually changes colour throughout the year.
A Japanese spacecraft is expected to reach Martian orbit in 2025 to collect material from the surface of the moon Phobos before returning to Earth by 2029.
Sixty years ago, philosopher Hannah Arendt argued an interplanetary perspective may be bad news for humanity as we know it.
Five of the Uranus moons might be ocean worlds − and if there’s water, there might be life.
Libyan desert glass originated from the impact of a meteorite on the Earth’s surface.
The Moon was formed when it collided with Earth billions of years ago.
Viral headlines would have you think Saturn’s rings will vanish in just 18 months. Here’s what that really means and why you don’t need to worry.
Upcoming NASA missions will help scientists understand the composition of asteroids – which could inform companies one day hoping to commercially mine asteroids.
A distant lump of space rock may have a surprising amount in common with the core of our own planet.
Studying the sample could help answer how water arrived on Earth and how life started.
The asteroid is interesting from a scientific perspective as well as a commercial one.
Controlled experiments are impossible in astronomy, as are direct measurements of physical properties of objects outside our solar system. So how do astronomers know so much about them?
NASA’s OSIRIS-REx mission has delivered pieces of asteroid Bennu, which scientists hope will offer a window into the early era of the Solar System billions of years ago.
