PRIANGAN ZONE – Temporary awan made of water on Earth, its composition is very different in planet another that far. Scientists have noted that some planet it has awan pasir silicates but cannot reveal the conditions under which they formed.
Now, a new study has revealed general properties conducive to development awan pasir. Led by researchers at Western University, the study used observations of brown dwarfs made by NASA’s Spitzer Space Telescope. Brown dwarfs are celestial bodies that are larger than planet but smaller than a star.
“Understand atmosphere brown dwarf dan planet the place awan silicates can form can also help us understand what we will see in atmosphere planet which is closer in size and temperature to Earth,” said Stanimir Metchev, a professor of studies planet exoplanet at Western University in London, Ontario, and co-authors of the study.

Formation of all kinds awan is the same where the main ingredient is heated to form steam. Once the material — which can be anything from water, salt, sulfur, or ammonia — is trapped and cools, awan formed.
The same principle is involved in the formation awan silica but because rocks require high temperatures to evaporate, awan such is only found in hot celestial bodies such as brown dwarfs, reports NDTV.
Researchers have used brown dwarfs in their research because many of them have atmosphere similar to planet gas-dominated like Jupiter.

The Spitzer Telescope has spotted the trail awan silica di atmosphere some brown dwarfs. However, the evidence is not concrete enough. In the new study, the researchers used more than 100 detections and grouped them according to the temperature of the brown dwarf. This helps them discover the definitive nature and range of temperatures in which awan silica is formed.
