Layers of rock provide a historical record of variations in the Earth’s orbit, revealing information about the planet’s climate billions of years ago.
A bright comet visible in December provides an excellent viewing opportunity for night sky lovers – even potentially with the naked eye.
The tilt of Earth’s axis as it orbits the sun results in the seasonal changes.
China’s Tiangong-1 space station is hurtling around Earth out of control and about to come crashing down. It’s just one of thousands of pieces of space junk left orbiting our planet.
The famous cosmologist was closely identified with black holes due to his revolutionary theoretical work explaining some of their mysterious properties.
The launch of Elon Musk’s Falcon Heavy rocket is undoubtedly a spectacular feat of engineering - but the release of a sports car into orbit also says something about our values as human beings.
When and where you see the Moon in the daytime depends on what phase it is in.
A bunch of uncommon things all happening at the same time mean this full moon will have some special attributes.
A solar day is a measure of how long it takes the Earth to rotate from one noon to the next, and today’s summer solstice also happens to be the longest solar day of the year.
We’ve all seen videos of satellites being blasted off into space - but once they’re locked in orbit around the earth, how do we bring them back down?
As technology advances, tiny satellites no bigger than a loaf of bread have advanced from just proving they work to being big contributors in answering science questions.
Letters from would-be girl astronauts in the 1960s tell part of the complicated story of sexism – in both NASA and the US at large – at the dawn of the space age.
Full moons are good reason to look up – and the one on Nov. 14 is no exception. But here’s why you likely won’t see something shockingly different from other full moons you’ve observed over the years.
Sonification is a technique for converting data into sound. It could transform the study of distant worlds.
Many of the new planets found in other star systems have some extraordinary orbital behavior. So what’s going on?
Cheap, affordable space travel would be revolutionary. Chances are, when it comes, it won’t rely on the brute force approach of rockets.
The Nobel Prize-winning research on neutrinos is expected to push the boundaries of science and technology.
Take a look at the moon and it isn’t hard to imagine it as a planet. A 3,476 kilometres-in-diameter ball of rock, with basalt plains and mountain ranges, whose gravitational pull produces tides here on…
