RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

In celebration of its 500th month of print, Astronomy magazine's March 2015 edition published an extensive collection titled "500 Coolest Things About Space." If you have ever tried to assimilate a list of even 50 interesting facts on any topic, you can appreciate the effort involved to come up with 500. I have been a subscriber to Astronomy, on and off, since sometime around 1980, and generally prefer it to the only other major astronomy-related publication, Sky & Telescope. Since RF Cafe's audience members are science minded, I figure you might appreciate a short version of some of the objects and events that are meaningful to most people.
I hereby offer a new word for those of us who are devoted to the study of the sky: 'philastropher.' Springboarding from the word 'philosopher,' which derives from the Greek 'philosophos' which means 'lover of wisdom,' (philo + astro) a 'philastropher' is a 'lover of astronomy.' Feel free to quote me ;-)
The Coup de grâce of the list, though, was item #500, as reproduced here. The photo was taken by NASA's Voyager 1 space probe while visiting Jupiter. "This narrow-angle color image of the Earth, dubbed 'Pale Blue Dot', is a part of the first ever 'portrait' of the solar system." Quoted is Carl Sagan:
"From this distant vantage point, the Earth might not seem of any particular interest. But for us, it's different. Consider again that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every 'superstar,' every 'supreme leader,' every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.
