Solar System Formation
Here, I show the early Solar System – well, not necessarily our solar system. Gas
and dust has lumped together to form asteroid-sized planetesimals, and these will
then come together to form the larger bodies astronomers call planetoids. Soon, the
...

Birth of the Moon
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...

planet, planet, accretion
Emergence of the Terrestrials
This shows a view towards the Sun in the days when the terrestrial planets were
forming from the protoplanetary disc, about 4500 million years ago. It shows an
advanced stage in the process of planet formation.

Fiery Birth
An illustration showing a primitive terrestrial planet, more properly called a
protoplanet, in the process of formation. The planet
grows as its gravity sucks in more and more rocky debris. The whole process takes
hundreds of millions of years.

Lunar Naissance
This one is similar to Chaos and Order. Both show the formation of the Moon. The young Earth (left) is still
surrounded by a ring of debris from which the Moon (right) has recently formed. The
debris is the result of the Earth having been hit by a la...

Molten Planet
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...

Protoplanet
This image is very similar to Fiery Birth andEmergence of the Terrestrials, showing a
primitive terrestrial planet, or protoplanet, in the process of formation, 4500 million years ago.

accretion, planetoid, planetesimal, formation
Big Bang
This is a conceptual representation of the Big Bang that theoretically created space
and time 13.7 billion years ago. The image is inaccurate in that the Big Bang was an
'explosion' of space, not in space, so it would not have been possible to regard...

Birth of the Solar System
What you see here is an impression of our Solar System forming, from the initial
supernova that started the contraction of a gas cloud. As the cloud collapses and
spins, it gets flatter. Soon, pieces of material in the disc begin to lump together
(ac...

Chaos and Order
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...
