Super-Earth planet zips through the habitable zone of red dwarf star

Astronomers have discovered a ‘super-Earth’ orbiting a red dwarf star just 37 light-years from our solar system. 

The exoplanet Ross 508 b skims the so-called habitable zone of its parent star, the area in which surface temperatures are suitable to allow for the existence of liquid water, a key ingredient of life. The newly discovered exoplanet has about four times the mass of Earth and was discovered using a new infrared monitoring technique. The proximity of this super-Earth to our planet means it is ripe for atmospheric investigation, which could help researchers determine whether life could exist around low-mass stars.
