Researchers may have identified the missing component in the chemistry of the Venusian clouds that would explain their colour and 'splotchiness' in the UV

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.

Scientists have discovered that, even in "pristine" solar systems, planets exhibit a bit of a tilt.

Five of the Uranus moons might be ocean worlds − and if there’s water, there might be life.

The Moon was formed when it collided with Earth billions of years ago.

Upcoming NASA missions will help scientists understand the composition of asteroids – which could inform companies one day hoping to commercially mine asteroids.

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?
