Webb ziet kwartskristallen in de wolken van een hete gasreus

Astronomen hebben met behulp van de Webb Space Telescope bewijs gevonden voor kwarts-nanokristallen in de hooggelegen wolken van WASP-17 b, een hete gasreus op een afstand van 1300 lichtjaar van de Aarde.

Currently a competitor in #MinCup23, #Quartz is a #crystalline form of silicon dioxide (#SiO2) with a trigonal #crystal system that, ideally, results in the growth of a hexagonal column with pointed ends, but nature rarely allows this, as this #Macro #image demonstrates.
