Astrophysicists have made a unique discovery, finding in the constellation of Taurus around protoplanetary stars warm water vapor. Previously, scientists had anything like this was not observed.
In the study, researchers have made a spectral analysis of the radiation of dozens of stars. The information collected by the modern spectrometer PACS, which is located on the space observatory "Herschel", developed by the European Space Agency and launched into orbit in 2009. Secure traces of water vapor scientists managed in six cases.
Astrophysicists have suggested that warm water vapor can live anywhere within about 3 astronomical units from the star, that is, within the protoplanetary disk. The temperature in this region reaches 600 degrees Kelvin, so the researchers found was called steam warm. On space standards such temperatures are not considered to be very high, rather average. As a source of water vapor can serve as an internal part of the protoplanetary disk. Protoplanetary disks are gas formations that orbit stars.
Scientists suggest that over time, these particles stick together and start to drive this way arise the planet. Water is found in the inner part of the disc - this is an area where they can form terrestrial planets.
Launched a telescope "Herschel" into orbit from Spaceport in French Guiana, May 14, 2009. Brought a telescope into orbit the European missile ’Ariane’. The main purpose of the telescope is to work in the submillimeter and infrared. It’s pretty powerful machine. The diameter of the mirror up to 3.5 meters, and it is a full meter more than the other big device "Hubble."
For the first time the water in the protoplanetary disk of another star found in March 2008. The discovery made telescope "Stitzer." Then the unit detects gas and dust clouds that were around a pretty young stars on space standards AS 205A and DR Tau. Star DR Tau was located at a distance of 457 light years from our solar system, and the star AS 205A to 391 years away. Then the scientists were able to determine the water vapor than that in the protoplanetary disk is also simple organic molecules such as HCN, C2H2, CO2, that may actually be a sign that around these stars after billions of years of Earth-like planets may form.
