What is responsible for the excess radio emission from our nearest star, Proxima Centauri? No alien radio stations required!
Scientists (and film producers) have been fascinated by the prospect for ET life for quite some time. Today’s authors create a model that predicts the biodiversity of a planet, and the results may not be what you expect. Check out this bite to see which stars are most likely to host complex life.
How does habitability vary on a galactic scale?
We can precisely measure chemical abundances for stars. This offers an intriguing possibility that we may, in the near future, start using these measurements to know more about the insides of rocky planets orbiting them.
Supernovae and Gamma Ray Bursts are expected to wipe out any complex life in the neighborhood. Today’s paper looks at how common these events are in different galaxies over time.
TRAPPIST-1 promises to be one of the best candidates for habitability in the solar neighborhood. Today we will see that the presence of a system-wide cloud of hydrogen could be traced to a history of water loss in the planets in this system.
