The aeronomic goal is to study certain molecules that are found in Earth's atmosphere — such as water, chlorine compounds and ozone — which can help us better understand the processes that cause thinning of the ozone layer.

They also found that each water molecule formed four hydrogen bonds — three with other molecules in the same layer, and one with water in the other layer.

Assuming an iron - rich planet with an internal structure like Earth, modelling results for the first discovered super-Earth (GJ 876 d) indicate the existence of a threshold in planetary diameter above which a super-Earth «most certainly» has a high water content (an «ocean planet» or «water world,» where thick layers of water and pressurized ice surround a rocky mantle and core); this threshold was found to be around 24,000 kilometers (or nearly 15,000 miles) in the particular case of GJ 876 d (Valencia et al, 2007).
