Astronomers have found "treasure chests" in space – a new class of planets containing many elements composed of sapphires and rubies.
Perhaps even they are brilliant, reports Science Alert
. only three planets on which there are probably many jewels. The first – HD 219134 b, is 21 light years from Earth, in the constellation Cassiopeia. The second planet 55 Cancri e is located at a distance of 41st light year. Third, WASP-47 th, the farthest – 870 light-years away from our planet.
The three planets belong to the type of superzemel – dense planets such as Earth and Mars, with a high proportion of stones, metals or their combinations, considerably larger (but nevertheless less than Neptune).
This sampling differs in that the planets revolve around their place of formation and have a composition completely different from that of the planets of the solar system. For example, the Earth's core is made of an iron-nickel alloy and the nuclei of these planets are rich in calcium and aluminum. This multiplies the probabilities that they contain a lot of sapphires and rubies formed from alumina.
