Life might emerge on a red dwarf planet, some now think, after the star has aged and its flares have settled down; winds on the planet might transport heat from one hemisphere to the other, keeping the atmosphere from freezing.

Named PH1, the planet goes around two of the four stars, shown close - up here: One is a yellow - white F - type star that is slightly warmer and more luminous than our sun; the other, at the 11 o'clock position, is a red dwarf, cooler and dimmer than the sun.

Other recent discoveries of nearby Earth - sized planets have been around red dwarf stars, including TRAPPIST - 1 and Proxima Centauri, but these create less favorable conditions for life.

Until now, the transits of only one other super-Earth, GJ 1214b circling a red dwarf, had been observed with ground - based telescopes.

One is probably a red giant that is still blowing off its atmosphere; the other is most likely a white dwarf stealing gas from its giant companion and lighting up the surrounding nebula.

In the other case, the companion may be an orange dwarf, whose properties lie between those of a red dwarf and the sun.

19 At the other end of the wetness scale, planet GJ 1214b, which orbits a red dwarf star, may be almost entirely water.

Given at least nine meters (roughly 30 feet) of water on the planet, photosynthetic microbes (including mats of algae, cyanobacteria, and other photosynthetic bacteria) and plant - like protoctists (such as floating seaweed or kelp forests attached to the seafloor) could be protected from «planet - scalding» ultraviolet flares produced by young red dwarf stars, according to Victoria Meadows of Caltech, principal investigator at the NASA Astrobiology Institute's Virtual Planetary Laboratory.

This phenomenon is known as «tidal locking,» and it means that Gliese 1132b evolved so close to the red dwarf that one hemisphere is permanently facing its star in perpetual day, while the other hemisphere is in eternal night.

Epsilon Indi is an orange - red dwarf star, with two methane brown dwarf companions in orbit around each other (more).

While the red dwarf's flares may strip away an atmosphere, if it doesn't, this «hot» side may be the perfect place to build an array of solar panels and move heat and energy to the other side.

Gravitational microlensing, on the other hand, results from the bending of light from much smaller and less massive stellar - type objects like brown dwarfs, red dwarfs, neutron stars, and black holes.

While other, more massive stars only burn through the hydrogen at their core before coming to the end of their lifetimes, red dwarfs consume all of their hydrogen, in and out of their core.
