Venus: Cloudy With A Chance Of Life Forms?
Max Seager is no different, with one big exception: for the third-year biochemistry major, those clouds are made of concentrated sulfuric acid, swirling high above the surface of Venus.

Stability of 20 Biogenic Amino Acids in Concentrated Sulfuric Acid: Implications for the Habitability of Venus’ Clouds
Scientists have long speculated about the potential habitability of Venus, not at the 700K surface, but in the cloud layers located at 48-60 km altitudes, where temperatures match those found […]

A Carbon-lite Atmosphere Could Be A Sign Of Water And Life On Other Terrestrial Planets
Scientists at MIT, the University of Birmingham, and elsewhere say that astronomers’ best chance of finding liquid water, and even life on other planets, is to look for the absence, […]

Atmospheres As A Window To Rocky Exoplanet Surfaces
As the characterization of exoplanet atmospheres proceeds, providing insights into atmospheric chemistry and composition, a key question is how much deeper into the planet we might be able to see […]

Turning Earth Into Venus: A Stochastic Model of Possible Evolutions of Terrestrial Topography
Venus may have had both an Earth-like climate as well as extensive water oceans and active (or incipient) plate tectonics for an extended interval of its history. The topographical power […]
