Atmospheric signs of volcanic activity could aid search for life

An eruption of the Calbuco Volcano in southern Chile. A team led by the UW's Amit Misra used data from volcanic eruptions on Earth to predict what an Earth-like exoplanet might look like during such eruptions.

Planets with volcanic activity are considered better candidates for life than worlds without such heated internal goings-on.
Now, graduate students at the UW have found a way to detect volcanic activity in the atmospheres of faraway planets when they transit, or pass in front of their host stars.

‘Dimer molecules’ aid study of exoplanet pressure, hunt for life

An artist's concept of an exoplanet, or planet outside the solar system.

UW astronomers have developed a new method of gauging the atmospheric pressure of exoplanets, or worlds beyond the solar system, by looking for a certain type of molecule. And if there is life out in space, it may one day be revealed by this method.
