Volcanoes of Io

 After the detailed imaging of Io, the fourth-largest moon in the Solar System, in 1979 by Voyager 1, it was concluded that Io is the most geologically active body in the solar system. It also has the lowest amount of water of any object in the solar system. Discovered by Galileo, the moon has more than 400 active volcanoes. The moon has mountain peaks taller than Mount Everest and its surface is mainly made up of iron and sulphur. Imagine mountains taller than Everest full of sulphur and iron oxides! These volcanoes are responsible for large clouds of gases around Jupiter. It is one of the only four volcanic active bodies in the solar system after Earth, Enceladus and Triton. Voyager 1 during its close flyby of Io experienced the strong tidal heating from the volcanoes. Also, the gravity of Jupiter changes the amount and direction of tidal heating. Lavas on Io are hundreds of kilometres long and are different from those on Earth. Lava on Earth is mainly made up of iron and magnesium,

Terraformation of Mars

Terraforming Mars is a hypothetical process to transform the entire Mars into an Earth-like planet. This requires a complete change of all factors of Mars including its temperature, pressure, water level, clouds, soil, etc. It would similar to playing TerraGenesis in real life. The ultimate goal of terraforming is to make Mars habitable for humans, plants, and other animals. For the process of terraforming Mars is the best planet because it has an Earth-like structure and most importantly Mars has water! Earlier scientists developed theories for the terraforming of Venus, but it was unsuccessful due to its extremely hot surface and acidic clouds.  Terraformation of Mars is impossible without changing its temperature and atmosphere. Mars is a giant storeroom of greenhouse gas mainly carbon dioxide. This creates a lot of problems in its atmosphere. An era of meteor hits has made the atmosphere very thin, making it easy for gases like oxygen and nitrogen to escape its atmosphere. If not f
