Astronomers have unearthed a huge gas giant planet with the density of a marshmallow, which is encircling a cool red dwarf star situated 580 light-years from Earth.
The Jupiter -like exoplanet is the lowest-density world ever seen orbiting a red dwarf, reports Space.com.
Red dwarf stars are the tiniest and dimmest stars and are still converting hydrogen to helium in their cores via nuclear fusion, which is a part of the star's life named "the main sequence".
