Planet-hunters have discovered two "super-Earths" orbiting two nearby Sun-like stars.
These rocky planets are larger than the Earth but much smaller than ice giants such as Uranus and Neptune.
Scientists say the discoveries are a step towards finding potentially habitable planets - smaller planets that are comparable to the Earth.
Details of the new planets are described in two papers in the Astrophysical Journal.
Two US-based scientists led the international research effort - Paul Butler from the Carnegie Institution’s Department of Terrestrial Magnetism in
Washington and Steven Vogt of the University of California, Santa Cruz.
They combined several years’ worth of data from the W M Keck Observatory in Hawaii, and the Anglo-Australian Telescope in New South Wales,
