An international scientific team, with the participation of researchers from the Instituto de Astrofísica de Canarias (IAC), confirms the existence of an Earth-sized planet orbiting an ultra-cold red dwarf located about 55 light-years from our planet. The result is reported in the journal Nature Astronomy. More than 70% of the stars in the Milky Way are M dwarfs, also known as red dwarfs. These stars are cool and dim compared with our Sun, and those ‘‘lives’’ last a long time. Stars like our Sun burn for about 10 billion years before turning into hungry red giants devouring any planets too
