Understanding the make-up and dynamics of atmospheric clouds is crucial to our interpretations of how weather and climate behave on Earth, and so it should come as no surprise that clouds are similarly essential to learning the nature and behavior of exoplanets. On many exoplanets, thick clouds and related, though different, hazes have been …
Exoplanet Clouds; Friend and Foe
Understanding the make-up and dynamics of atmospheric clouds is crucial to our interpretations of how weather and climate behave on Earth, and so it should come as no surprise that clouds are similarly essential to learning the nature and behavior of exoplanets. On many exoplanets, thick clouds and related, though different, hazes have been impediments …
Cloudy, With a Chance of Iron Rain
From an Earthcentric point of view, rain of course means falling water. We can have storms with falling dust -- I experienced a few of those while a reporter in India -- but rain is pretty much exclusively H2O falling from the clouds. But as the study of exoplanets moves aggressively into the realm …
On Super-Earths, Sub-Neptunes and Some Lessons They Teach
Part 2 of 2 With such a large proportion of identified exoplanets in the super-Earth to sub-Neptune class, an inescapable question arises: how conducive might they be to the origin and maintenance of life? So little is actually know about the characteristics of these planets that are larger than Earth but smaller than Neptune …
