Astronomers found out a Dusty disk over the young star

Icy disk over the young star

 The  astronomers from Herschel Space Observatory center have found out an dusty disk over the young star for the first time.they have found out that there  are large quantities of water in the disk.The scientistists found that there is a warm vapour in the disk planet forming in the central star.
The astronomer named Michiel Hogerheijde of Leiden Observatory in  Netherlands says that cold vapour indicates that water exists in the disk. TW Hydrae is disk that contails water logged in the disk,it is about 10 million years old located from the 175 years light years away from the earth. TW Hydrae is a orange dwarf starthat is smaller and cooler than the yellow white star .The giant disk of material that is seen is nearly 200 times the distance between the earth and the sun.Due to this dust and ice paricles combine dtogether and form ice comates when collision occurs between them they grow like a planets.

Astronomers say that icy comets have more water thatthey develop oceans of impact .TW Hydrane and icy disk represents many other young star systems providing new insights of planets .
