Washington, DC: The researchers again found a new planet that has never teridentifikiasi. The new planet is tracked through the Hubble telescope was completely filled with water. As reported from TGDaily, Wednesday (22/2), the planet, named GJ 1214b is the world's water is surrounded by a thick vapor.
"GJ 1214b is not like the planet we know. Almost all of its mass consisting of water," said Zachory Berta, one of Astrophysics.
The research team used three cameras of the Hubble to study GJ 1214b when crossing in front of the source star. They analyze the starlight filtered through the planet's atmosphere. They found the spectrum of GJ 1214b into the specific nature of the various wavelengths and showed dense atmosphere of water vapor.
Based on the data obtained, the planet has a mass density and size of the planet is only about two grams per cubic centimeter, less than half of the Earth. With the density of water is only one gram per cubic centimeter, the implication is that GJ 1214b has more water than Earth. However, the planet was reported to lack the rocks.
Initially, the planet had been discovered in 2009 ago. Planet GJ 1214b has about 2.7 times Earth's diameter and weighs seven times that of the world. The planet is orbiting a red dwarf star and has a temperature of 230 degrees Celsius. However, until now, researchers still do not know the composition of the planet. (BOG)
