Oxygen: The jerk of the elements. It's corrosive, burns like crazy, and is generally reactive and unstable. Oxygen, on the other hand, is about as stable as a drunk unicyclist. When you find oxygen in nature (and by “nature” I mean “other than Earth”) it’s always already ti...
Learn how Venus got its name, the distance of the planet from Earth, the length of a day, and other interesting facts about the planet. Related to this QuestionDoes Mars have a magnetosphere? What is the magnetosphere like on Venus? Does Venus have a magnetic field? Does Mercury have a ...
Ceres is uncertain in this respect as that world is unlikely to ever have hosted a significant atmosphere and its potential status as an early ocean world is still debated. The irony here is that a Mars free of life is a unique and scientifically valuable asset for understanding the rise of...
It turns out that extracting the oxygen is not very easy --airhas something like 20 times more oxygen in it than the same volume of water. Plus water is a lot heavier and thicker than air, so it takes a lot more work to move it around. Do humans naturally float? With very few exc...
and a salt-water ocean is believed to exist nearly 200 km below Ganymede’s surface – though Europa remains the most likely candidate for this. Ganymede has a high number of craters, most of which are now covered in ice, and boasts a thin oxygen atmosphere that includes O, O2, and pos...
Human life and even most life could not have survived in such an atmosphere. With the evolution of photosynthesizing plants, the concentration of CO2 dropped and the percentage of oxygen in the atmosphere increased. Remember that in photosynthesis: CO2 +H2O + energy from sun ==> O2 + ...

Earth has a magnetic field extending between the north and south poles. The planet's rotation around its axis and the movement of liquid iron inside the Earth contribute to creating the magnetic field. When an iron-rich minerals such as magnetite becomes hot enough it loses their magnetic prope...
