An illustration showing a primitive terrestrial planet, more properly called a protoplanet, in the process of formation. We view the newborn world from its troubled surface, and a whole host of similar worlds is visible in the sky before us. This ima...

Here I show the Earth in the deep future, when our technology has advanced to the point that we can clearly see it from orbit. Or perhaps it's a different planet elsewhere in the universe, somewhat like the Earth but having a greater technology than ...

In this image I imagine an Earth-like world in orbit around not a single star but a close binary. What beautiful sunsets could be witnessed from this world. In the sky I have added a giant satellite, its night side illuminated by cities, betraying in...

Witness the formation of the Moon. The young Earth (right) is still surrounded by a ring of debris from which the Moon (left) has recently formed. The debris is the result of the Earth having been hit by a large protoplanet. This image appeared in Ea...

In this movie, the lowland areas of Mars are covered in a blue sea. Mars' two moons, Phobos and Deimos, are seen transiting across the planet in that order. It is thought that liquid water existed on Mars millions of years ago, but it is now too cold...

Astronomers are uncovering more and more evidence that seems to indicate that the planet Mars, now dry and lifeless, was once able to support liquid water. This impression shows the red planet in the future, when humans have terraformed and colonised...

This is the same kind of binary star system (a cataclysmic variable) as depicted Cataclysm III and VI this time seen from a cave on a purely hypothetical, watery and rocky planet. Admittedly, though, such a situation is highly unlikely to exist in re...

How the Moon formed is something astronomers have been wondering for ages. The best idea is that put forward by Bill Hartmann – an astronomer and fellow space artist – and Donald Davis. They assert that a massive protoplanet slammed into Earth ju...

A view of the early Earth and Moon system, still enduring the seemingly endless bombardment of planetesimals and comets that rained down for the first several hundred million years of the pair's existence. It is thought that impacts by icy comets hel...

A giant star, reaching the inevitable end of its fuel supply, explodes in a tremendous explosion – brighter than a hundred billion stars – called a supernova. The force from the blast throws the remains of the star deep into space, where they wil...
