During the observation of young luminaries TW Hydra Space Telescope, “Herschel” discovered massive ice deposits.
TW Hydra very young star - its only about 10 million years and it still not yet reached the main sequence. TW Hydra is two times lower than the Sun in mass and is removed from us to 53,7 ± 6,2 parsecs. The star has a large protoplanetary disk with a radius of 196. It is concentrated (2–6)x10 -4 solar masses of dust and 4×10-5 – 6×10 -2 mass of gas.
It is believed that water vapor is collected only in the “warm” part of the protoplanetary disk, and ’cool’ outer regions, it only exists in the form of ice. However, with ultraviolet radiation, the star still converts some of the ice in the gas phase. This “cold” pairs in the protoplanetary disk TW Hydra spectrograph and registered HIFI on board the ”Herschel.” It is possible to determine the general water supply.
As the scientists think, the mass of ice in the disk is TW Hydra is 9×1027 g, which is more than a thousand times greater than the amount of water, concentrated in all the seas and oceans of Earth.
