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 15 articles and 22 specialist blog posts about planetology so far, featuring 179 unanswered planetology questions! But we're not done yet as we still have another 80 planetology research areas in our database to write about, so come back soon!

New Global River Map Is the First to Include River Bifurcations and Canals
16th May, 2025
GRIT provides a much more detailed look at how rivers merge and split, which could enhance hydrological modeling, flood forecasting, and water management efforts.
Building Climate Resilience in Communities at Home and Abroad
15th May, 2025
M.A. in Climate and Society student Anar Amarjargal hopes to bring the lessons from her work on global climate projects and disaster recovery back home to Mongolia.
Geo-engineering, the controversial set of techniques that aim to deliberately alter the Earth’s climate system, may be inching a step closer to reality with the announcement that UK scientists will be conducting real-world experiments in the coming years. To understand what’s happening, Ian Sample is joined by the Guardian environment editor Damian Carrington. Damian explains…
We don’t know what causes lightning, how much of it there is, nor how to predict it. As global temperatures increase, so does lightning; as lightning increases, so do global temperatures. Its impact on atmospheric chemistry is still being explored.
Geoengineering the climate would mean venturing into new technology with huge consequences. But what might those consequences be and is there an alternative solution to anthropogenic climate change?
Chemists are exploring ways to mimic nature’s selective, low-temperature biochemical reactions that make delicate and reactive structures. Previously, chemists had copied high temperature geological reactions.
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?
Jupiter is the largest planet in our solar system. It’s been observed since Babylonian times, yet we know little about what goes on inside this giant red planet.
