Fermi suggested there may be no intelligent life in the universe, outside of brief episodes confined to planetary surfaces before they develop science and end themselves.

In the search for other Earths, the main goal is to find a planet the same size as ours that sits in the habitable zone — the region around a given star where planetary surface temperature would be similar to ours, allowing liquid water to exist.

Scientists record the size and number of impact craters — and how eroded they are — to determine the ages and histories of different planetary surfaces.

We hypothesize that the global climate variations of the Cenozoic (figure 1) can be understood and analysed via slow temporal changes in Earth's energy balance, which is a function of solar irradiance, atmospheric composition (specifically long - lived GHGs) and planetary surface albedo.

The moon appears to be a tranquil place, but modeling done by University of New Hampshire and NASA scientists suggests that, over the eons, periodic storms of solar energetic particles may have significantly altered the properties of the soil in the moon's coldest craters through the process of sparking — a finding that could change our understanding of the evolution of planetary surfaces in the solar system.

«Water plays a critical role in determining the tectonic behavior of planetary surfaces, the melting point of planetary interiors and the location and eruptive style of planetary volcanoes,» said Erik Hauri, a geochemist with the Carnegie Institution of Washington and lead author of the study.

But looking for these molecules on Mars or other planetary surfaces has been a major challenge.

Eris and Pluto share a very similar planetary surface, that is mostly covered in nitrogen ice with a small amount of methane ice (more).

The fact is that unless one can properly appreciate the nature and scale of the effect that an atmosphere has on planetary surface temperature then the significance of my article and indeed the entire underlying debate is impossible to assess meaningfully.
