  • Astronomers detected the evidence of quartz nanocrystals in the high-altitude clouds of the exoplanet WASP-17b.
  • WASP-17b is a “hot Jupiter” exoplanet about 1,300 light-years away from our planet.
  • The detection is the first time that silica particles have been detected in the atmosphere of an exoplanets.
  • Silicates are minerals rich in silicon and oxygen and they make up a bulk of Earth and the Moon’s mass, as well as other rocky objects in the solar system.
  • They are extremely common across the galaxy.
  • But the silicate grains that were detected so far in the atmospheres of exoplanets and brown dwarfs seemed to be made of magnesium-rich silicates like olivine and pyroxene.
  • Quartz is pure silicon dioxide.
