* With acknowledgement and thanks to Star Hustler / Star Gazer, Jack Horkheimer (1938 - 2010), who hosted the world's first and only weekly TV series on naked-eye astronomy for over 30 years and 1,708 episodes, since it first aired in 1976. Jack passed away August 20th at the age of 72. He would always begin his shows with "Greetings, greetings fellow star gazers" and would always end them with his now famous words of encouragement to "keep looking up!".
Some sunspots are cool enough that water vapor can form at a temperature of 1,550 °C.
