Unlike our hellish neighbour Venus, Earth was far enough from the Sun for liquid water to form and create a more hospitable environment for life.
After two decades as a home to astronauts, the International Space Station still has plenty to teach us about how humans can live away from Earth.
Bennu will tell us about our own origins as much as about the origin of asteroid Bennu.
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.
Three newly discovered bodies of liquid water deep beneath the south polar ice cap on Mars have planetary scientists intrigued.
The clouds of Venus may harbour alien life. But where else?
A small asteroid will cross Earth’s orbit on November 2. Scientists aren’t sure if the two will collide – but even if they do, there’s still no cause for alarm.
Pluto began hot inside, study of its surface fractures suggests
In the search for the hypothetical Planet Nine, scientists may have uncovered another explanation for the patterns in the orbits of Kuiper Belt objects.
The Earth and the Moon were long thought to be virtually identical in composition. Now we know they are not.
Earth currently has a second moon - but it won’t stay long.
Why isn’t there an endless variety of planets in the universe? An astrophysicist explains why planets only come in two flavors.
Saturn’s largest moon has been fully mapped for the first time.
Astronomers have found 20 new moons around Saturn, and will keep finding more as technology improves.
A giant exomoon hundreds of times the size of Earth is revealing secrets about how giant planets like Jupiter and Saturn formed. They might also help astronomers find planets where life may thrive.
Kepler-452b is sometimes called ‘Earth 2.0’, but there’s a lot we still don’t know about it.
Most people think that many millions of years ago, Saturn didn’t have rings at all. Instead, it had a big moon moving around it. Eventually, the moon burst and broke into pieces.
This hot, acidic neighbor with its surface veiled in thick clouds hasn’t benefited from the attention showered on Mars and the Moon. But Venus may offer insights into the fate of the Earth.
A 100-metre-wide asteroid passed just 70,000km from Earth on Thursday, and we had little warning it was about to happen. What threat is posed by asteroids and how do we find them?
