One-dimensional models show how the expected variability in radiogenic heat from U and Th in a rocky planet’s mantle could control the presence of a magnetic field and thus habitability.
Who is phosphine and why do we care? Have we found alien life? or is it just rock farts? This astrobite summarizes the Nature paper describing the detection and potential implications of phosphine in the atmosphere of Venus.
M dwarfs are known to be really active when they’re young, which is bad for habitability. But what about old M dwarfs?
We discovered Earth-like planets but are they the next destination for human life?
What happens when you take an Earth-like planet and tilt it nearly on its side? For life, its not as crazy as it sounds.
Sunlight fuels photosynthesis here on Earth, which in turn sustains all life on our planet. But how would this crucial process work on planets which orbit fainter stars?
