Days numbered for Herschel space telescope

Most powerful infrared telescope ever put into space will soon be retired since coolant is running low.

    The Herschel space observatory telescope has been orbiting the Sun for the last three years, taking pictures of the coldest parts of the universe.

    Now its coolant is running low and since refuelling is impossible, the largest, most powerful infrared telescope ever put into space will soon be retired.
