- 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.
