The current progress in the detection of terrestrial type exoplanets has opened a new avenue in the characterization of exoplanetary atmospheres and in the search for biosignatures of life with the upcoming ground-based and space missions.

It is currently unknown how common life is on exoplanets, or how long planets can remain viable for life.

The search of life in the Universe is a fundamental problem of astrobiology and a major priority for NASA.

The Space Weather of Proxima Centauri b

A planet orbiting in the "habitable zone" of our closest neighboring star, Proxima Centauri, has recently been discovered, and the next natural question is whether or not Proxima b is "habitable".

I review some recent works on magnetism of cool, main-sequence stars, their winds and potential impact on surrounding exoplanets. The winds of these stars are very tenuous and persist during their lifetime.

Our sun's adolescence was stormy-and new evidence shows that these tempests may have been just the key to seeding life as we know it.

The onset and nature of the earliest geomagnetic field is important for understanding the evolution of the core, atmosphere and
life on Earth.
