|This piece of research has tripled the estimate of the number of habitable planets in the universe – we are probably not alone!
Lost in Space
We look, we seek, we question why.
|Notes: “Star is crowded by super-Earths.” Scientists have identified three new planets around a star in the constellation of Scorpio. The star, Gliese 667C is 22 light-years away and is a low-luminosity “M-dwarf” star just over one-third the mass of our Sun. The discovery means there are three so-called super-Earths orbiting in its “habitable zone”. This is the region where temperatures ought to allow for the possibility of liquid water, although no-one can say for sure what conditions are really like on these planets. The discovery demonstrates that low-mass stars can be hosts of several potentially habitable planets which means that we might have to double or treble our estimates for the occurrence rate of habitable-zone planets around M-dwarf stars. So, although only a rather simple discovery, its implications might force a re-think of how common habitable-zone planets are in the Universe..|
