Some M stars are excellent candidates to search for terrestrial worlds that lie in their habitable zone (liquid water orbital distance range). Proxima Centauri, for instance, is a cool red dwarf star about 4.2 light-years from our Sun, which harbors a planet in its habitable zone. This exop...

Earth-sized exoplanet in ‘habitable zone’ is one of closest yet to our world NASA spacecraft also spots an alien world orbiting two stars. By Alexandra Witze Honolulu, Hawaii Access options Access Nature and 54 other Nature Portfolio journals...
For instance, given the planet’s distance from its sun – 0.05 AU (7.5 million km; 4.66 million mi) – there have been questions about the planet’s orbital characteristics. On the one hand, it could be tidally-locked, where one face is constantly facing towards Proxima Centauri. On the...
I find it very hard to believe there has never been any form of life on another planet. I do agree we will not find factual life… We will never see it, unless humans can live at least 25k years and travel at light speed (no mass)… But thats not why we expl...
As close as it is at a distance of 8.29 light-years, it is not likely that humans will travel to Lalande 21185 any time soon. Still, astronomers will keep checking on possible worlds and their habitability for life. Sirius Mellostorm/Wikimedia Commons/CC BY 3.0 ...
14 light years away. The planetary habitable zone around the star is marked in green — the colors grade from red (where a planet would be too hot), through green (where the surface of a planet could sustain liquid water), through to blue (where a planet would be too cold). (credit...
it might be one of the first destinations for manned expeditions outside our solar system. The discovery was made by Kevin Luhman, an associate professor of astronomy and astrophysics at Penn State University and a researcher in Penn State's Center for Exoplanets and Habitable Worlds. This diagra...

The habitable zone is the area around a star at which water can be liquid on a rocky planet's surface, therefore considered ideal for sustaining life. As the researchers note, planets outside the habitable zone could certainly harbor life, but it would be extremely difficult to detect any si...
