Every night the window of my room opens my eyesight over an awesome universe of stars.

Outside the window the environment is hostile. The temperature stays between -55°C and -75°C and the average pressure is around 644.4 hPA. Is a double window and between the two windows the temperature stays between -22°C and -41°C. The border of external window is covered by a thick layer of ice. The day (or when i lit the light) the internal window glass show a spectacle of ice cristals.
