The researchers discovered a unique "scintillating" planet located 21 light-years from Earth and located in the constellation Cassiopeia, which can give a new insight into viable outer planets.
Astronomers say that unlike the Earth, the newly discovered planet HD219134b does not contain a massive mass of iron, but that it is rich in calcium and aluminum, which makes it very rich in precious stones.
"The planet can cast a blue-blue luminosity, such as blue sapphires, because these are the common aluminum oxides to the outer planets," said Carolyn Dorn, astronomer at the Institute of Computer Sciences of the United States. University of Zurich, who led the new study.
With a mass five times greater than that of our planet, the planet calls itself "Super Earth" and one of the three planets will likely belong to a strange new layer of outer planets, according to the researchers.
During its formation, the stars like the sun were surrounded by a disc of gas and dust in which the planets were born. Rocky planets such as the Earth were formed from the remains of solid objects when the primordial gas was dispersed.
"Usually, these building blocks are formed in areas where condensed rock elements, such as iron, magnesium, and silicon," Dorn said. The resulting planets are characterized by a composition similar to the earth with an iron core.
The researchers are also correcting a previous image of "Super-Earth 55 Cancri e", which dominated the news in 2012 under the title "Diamonds in the Sky". They had previously assumed that the planet was made of carbon, but they had to abandon that theory on the basis of later observations.
