Strangest water in space

Astronomers from NASA observed the strange weather conditions prevailing on the planet "55 Cancri e" located about 40 light years from Earth. Due to the prevailing there, extremely high temperatures and extremely highpressurewater molecules are located in the so-called. supercritical state.
"55 Cencri e" is one of the exoplanets, or planets outside our solar system. It was discovered already in 2004 and immediately became curious of scientists. Her time of circulation around the central starofis only 18 hours, and the rocky surface structure can include "55 Cencri e" to a group of planets called "SuperEarths". In addition, NASA astronomers have discovered that in the atmosphere is water!
Unfortunately, despite the occurrence of this life-giving substance, we can never settle "55 Cencri e". And all because this planet is truly from hell. There on the temperature reaching 1000 degrees Celsius and very high pressure. Such conditions shall be supercritical. Under the influence of hot water turns into gas and water vapor located under high pressure to the liquid state. In supercritical conditions at the same time we are dealing with extremely high pressure and very high temperature, which causes the disappearing boundary between liquid and gaseous state. This means that the "55 Cencri e" all liquids, including water well, all the time evaporate from the surface to form dense clouds floating in the atmosphere. Astronomers have discovered the planet representing the opposite of "55 Cencri e". It is the Eris dwarf planet located on the outskirts of the Solar System. Due to such a large distance from the Sun reigns on the extreme low temperature. These conditions led to the glacial atmosphere Eris. It is rather unusual phenomenon in space, like the presence of supercritical conditions on the planets.
Who knows maybe these conditions are good for extraterrestrial?:)

  1. yes it is strange. where did the water come from? Is it alien or human made?
