Astronomers have found "treasure chests" in space – a new class of planets containing many elements composed of sapphires and rubies
As Science Alert writes, they can be brilliant
For now, only scientists have discovered three planets likely to have a lot of 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 super-lands – dense planets such as Earth and Mars, with a large 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 chances that they contain a lot of sapphires and rubies formed from alumina.
- The unusual inclination of Uranus, which distinguishes its orbit from others in the solar system, may be associated with a collision with a huge ice-covered protoplanet. , Twice as hard as the Earth.
- New photos of the nascent planet for the first time: European astronomers photographed the planet at the formation stage in the protoplanetary disk surrounding the young star for the first time in its history
- Scientists claim to have found the evidence of the existence of water. Geyser is the smallest of the four largest satellites of Jupiter called Galilee, Europe
- Learn How -. To fly through the Orion nebula. NASA's astronomers and visualization specialists combined the data from the Hubble and Spitzer space telescopes (visible and infrared) and created a video of this flight.
