Highway to the Venus Zone
How much carbon dioxide is too much? Is the habitable zone always habitable? To answer these questions, today’s authors turn up the heat and shove it into overdrive on the highway to the Venus zone!
From Earth Plants to Exo-plants: Spectropolarimetry as an Agnostic Biosignature
In order to find life elsewhere in the universe, we need to rule out false positive biosignatures. To get around this, today’s authors use polarized light to distinguish plants from rocks!
How the Moon helped mold the Earth into a habitable potato
How did the Earth keep from freezing over under a faint young Sun 4 billion years ago, and what could it have to do with potatoes and the Moon?!
Hydrate or Die-drate: Was Venus Ever Habitable?
Could Venus have ever boasted the expansive oceans we find on Earth today? Find out by reading today’s bite about planetary scientists that modeled Venus’s atmosphere!
Ecology to Astrobiology: Modeling the Habitability of Other Worlds
The field of ecology already has standardized models for determining a region’s habitability. How can astrobiologists use these models to determine habitability beyond Earth?
Liquid Water on Exomoons beneath Sunless Skies
Could there be life in an obscure place, such as around a free floating planet, a so-called rogue? Today’s paper looks at the possibility of liquid water on moons of starless planets!
