An astronomer takes us on a tour of the universe to learn about the birth of stars and planets and how they get their spin.
Since ancient times, the stars have been set to music. Modern technology now enables scientists to convert images of space into real compositions.
Believe it or not, this sort-of happened before in Earth’s history – and now we have the Moon.
Sophisticated equipment on the Perseverance rover is helping answer some of the many questions researchers have about Mars’ geology over time.
Mars is the fourth planet from the Sun and one of our closest neighbors in space. But it’s not a very welcoming place for an Earthling to visit.
The dwarf planets in our Solar System are cold, dark, far away and full of surprises.
The sun has entered a phase causing more chances to see the northern lights in the UK, an expert explains.
Some planets are rejected by the Solar System that gave birth to them.
Clouds, hellish temperatures, endless nights? Characterizing the atmosphere of exoplanets, planets that orbit stars other than the sun, is a formidable task.
On the ultra-hot exoplanet WASP-76b, metal is vaporized in the heat. Studying the atmosphere of extreme planets will reveal more wild and weird weather.
In 5 billion years the Sun will collapse. A new discovery suggest some planets may still survive afterwards.
Scientists have a good estimate on the staggering number of stars in the universe.
Gravity, mass and centrifugal force all contribute to the final shape of a planet.
From the tallest cliff in the solar system to its largest impact basin, geological processes on other worlds are very similar to those on our own planet.
Billions of galaxies are in the universe, with billions of stars in every galaxy. Could billions of planets be out there too?
The reason bigger objects in space are round and smaller ones aren’t boils down to gravity. And it’s the same reason mountains on Earth can only grow to a certain height
Mars, Venus and the crescent Moon will all come together in the sky just after sunset on Tuesday.
Researchers used decades-old radar data and found that some low-lying areas of Venus’ crust are moving and jostling. This evidence is some of the strongest yet of tectonic activity on Venus.
Astronomers know a lot about what’s in outer space – and think it’s possible it never ends.
