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!

Dental health benefits of fluoride in water may have declined, study finds
4th October, 2024
Researchers say wider use of fluoride toothpaste means practice now has less of a role in reducing tooth decay
The red dwarf Barnard's Star is the closest single star to the Sun, only six light-years away. Astronomers have announced the discovery of a planet with half the mass of Venus, orbiting the star every three days. This puts it too close to be in the habitable zone, with a surface temperature of 125 °C. The team also found a hint of three additional planets in the system but will require further ob…
An Earth-like Planet Around a Dead Sun Provides Some Reassurance About the Future of Earth
2nd October, 2024
In about five billion years, our Sun will exit its main sequence phase and transition to its red giant phase. At this point, the Sun will expand and consume the planets of the inner Solar System, including Mercury and Venus. What will become of Earth when this happens has been the subject of debate for …

We Don’t See Many Planets in Old Triple Star Systems
1st October, 2024
Why is it important to search for exoplanets in triple star systems and how many can we find there? This is what a recent study accepted by Astrophysics & Space Science hopes to address as a pair of researchers from the University of Texas at Arlington investigated the statistical likelihood of triple star systems hosting …

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.
