Planetary Science TWDK Planetary Science (Planetology) doodle by Giles Meakin

Planetary Science, or Planetology, is a rapidly growing branch of science which describes the study of planets, celestial objects that are like planets, and anything which affects their shape, composition, appearance, or behaviour. As the study of planets includes the study of their structure and composition, atmosphere and climate cycles, their natural satellites and their interactions and relations with them and their star, planetary science overlaps greatly with some of the more traditional scientific disciplines.

The planet we know best is, of course, the one we are living on. Other planets can be studied remotely, using telescopes to observe them from a distance, while Space agencies around the world send robotic spacecraft to orbit, fly past or land on our planetary neighbours, and a dozen men have visited the moon.

We've published 10 articles and 22 specialist blog posts about planetology so far, featuring 133 unanswered planetology questions! But we're not done yet as we still have another 83 planetology research areas in our database to write about, so come back soon!

Extraterrestrial life
The search for alien life catches many people's imagination and has always been a very public branch of science. So with all this investigation, why has our search revealed nothing? Are we truly alone in the Universe?

Water
Water is vital for our survival, but how much do we really know about it?
