Red dwarfs are by far the most common type of star in the Milky Way galaxy, at least in the neighborhood of the Sun, but due to their low luminosity, individual red dwarfs cannot easily be observed. From Earth, not one is visible to the naked eye. Proxima Centauri, the nearest star to the Sun, is a red dwarf (Type M5, apparent magnitude 11.05), as are twenty of the next thirty nearest. According to some estimates, red dwarfs make up three-quarters of the stars in our galaxy. en.wikipedia.org...
Red dwarf stars may be small, but they could be critical in the continuing hunt for exoplanets and the possibility of finding habitable alien worlds. In a new study, an international team of astronomers have estimated that every red dwarf in our galaxy hosts at least one exoplanet and that one quarter host super-Earths orbiting within their habitable zones.
ANALYSIS: Smartest Aliens May Live Around Red Dwarf Stars
The scientists say the best place buy real estate for long-term habitability is around a red dwarf star. A planet can remain cozy for advanced life for a stretch of time that is five times greater than for Earth. All other thing being equal, this suggests that SETI searches should target red dwarfs to see if they are home to advanced civilizations that do not have to worry about the clock running out.
Like most people I expect there is extraterrestrial life but am not as certain about whether it's intelligent because lets face it; even on Earth intelligent life has been absent for 99.999% of Earth's history, so by that measure it's extraordinarily rare even here.
Anyway...that is a lot of planets!! Life as we know it is out there. No doubt in my mind what so ever!! Is there one person out there that doesn't (hate to say believe that) think so ????
most stars in our galaxy are red dwarfs, which flare violently, mostly in X-rays, a property not conducive to life as we know it. Simulations also suggest that these bursts erode planetary atmosphere.

We're a grain of sand on the oceans of the universe, yet some would think we're all alone, whereas in truth, life is abundant.
