The Herschel Space Telescope has closed its eye on the universe.

After four years of operation, the telescope’s supply of helium coolant has run out, leaving the infrared telescope blind to the sky.

    Another Herschel closed his eyes earlier this month. My father Herschel Smith Jr. 83 years old, passed away April 3rd a few weeks ago. He had a good life and was a good father. Funny how things in life work.
