Researchers have discovered a new exotic planet outside our solar system in the constellation Cassiopeia.
Located 21 light years away from us, this planet, dubbed HD219134 b, has a mass almost 5 times that of Earth, which is considered a so-called "super-Earth".
Unlike the Earth, however, it most likely does not have a massive core of iron, but is rich in calcium and aluminium alongside magnesium and silicon.
It shimmers red to blue like rubies and sapphires, because these gemstones are aluminium oxides which are common on the exoplanet.
