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!

NASA is Building a Space Telescope to Observe Exoplanet Atmospheres
19th January, 2025
The exoplanet census continues to grow. Currently, 5,819 exoplanets have been confirmed in 4,346 star systems, while thousands more await confirmation. The vast majority of these planets were detected in the past twenty years, owing to missions like the Kepler Space Telescope, the Transiting Exoplanet Survey Satellite (TESS), the venerable Hubble, the Convection, Rotation and …

NASA Study Reveals Alarming Shifts in Water Cycle Driven by Human Actions
17th January, 2025
NASA scientists have uncovered groundbreaking evidence that human activities are reshaping the global water cycle in ways never seen before. Using nearly 20 years of satellite data, the study highlights trends in groundwater depletion, shifting seasonal patterns, and increasing extreme weather events, all tied to human intervention.
Climate School Experts on the Los Angeles Fires: Causes, Impacts and Recovery
16th January, 2025
As California battles devastating wildfires, our researchers are helping to make sense of how they became so destructive, and what's needed for recovery.
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.
