According to recent observations relative number of flare stars does not change very much from cool dwarfs to hot A stars.

Hunting for habitable exoplanets now may be easier: Cornell University astronomers report that hydrogen pouring from volcanic sources on planets throughout the universe could improve the chances of locating life in the cosmos.

Planets with volcanic activity are considered better candidates for life than worlds without such heated internal goings-on.

Geological activity is thought to be important for the origin of life and for maintaining planetary habitability. We show that transient sulfate aerosols could be a signature of exoplanet volcanism, and therefore a geologically active world.

New three-dimensional reconstructions show how some of the earliest animals on Earth developed, and provide some answers as to why they went extinct.

Heat from a volcano erupting beneath an immense glacier would have created large lakes of liquid water on Mars in the relatively recent past.
