... sinking or forming cloud layers, and making them easier to detect. Well-known ingredients such as water vapour, carbon dioxide and methane will be searched for with ARIEL’s metre-class telescope that looks at the molecules in visible...
... the bedrock, any lingering liquid stuff is long gone - on the surface at least. Water ice and possible carbon dioxide ice does exist at the martian poles however and the presence of liquid water at the base of the...
... which could sustain surface habitability. The team found that if GJ 357 d has a geological cycle that regulates carbon dioxide concentration like on Earth, then the surface would be lovely and warm and possibly quite liveable. However...
...is essential for life as we know it. On Earth organisms such as algae, plants and trees convert molecules such as carbon dioxide (CO2) into oxygen (O2) – molecular oxygen, O2, and atomic oxygen, O, are both referred to as oxygen – in a process called...
... is a scant amount of moist convection circulating the planet. Also unlike Earth, the atmosphere’s main component, carbon dioxide (CO2), preferentially condenses on the Martian polar regions and in the middle atmosphere. Overall, the data gleaned...
... escaping Mercury’s subsurface. These volatiles, or volatile-rich compounds, include chemicals such as nitrogen, water, hydrogen, carbon dioxide and sulphates, stretched as far down as at least 2.5 kilometres, if not further and in some areas and...
