Carl Sagan Day 2018

Happy 10th Annual Carl Sagan Day!

As of tomorrow, it's been a full decade of HAIL, SAGAN! Once again, colleges and museums have planned awesome planetarium shows, educator workshops, family activities, telescope classes, and star-gazing. From Carl Sagan book readings in SC to Florida Meetups for Carl Sagan Day to MIT lectures Sagan Day 2018, celebrations honor what would have been Sagan's 84th birthday.

Best known from the original COSMOS series of the 1980s (the most widely watched program in PBS history!), Carl Sagan is known for his part in the Voyager Golden Records aboard spacecrafts Voyager I and II, and their longevity; his many fiction and non-fiction books packed with highly-quotable written material, and his tireless advocacy for science and astronomy.

He is immortalized in a science museum near his Ithaca, NY home, which includes the Carl Sagan Planet Walk scale solar system, complete with stampable passport at every planet, and narrated by Bill Nye the Science Guy.

Sagan taught at Cornell and Harvard universities, and worked at the Smithsonian Astrophysical Observatory. Other titles included technology officer of the Icarus planetary research journal, Planetary Science Chair at the Astronomical Society, Astronomy Chairman at the Advancement of Science Association, and Co-Founder of the Planetary Society, the Earth's largest space-interest group.

Carl Sagan passed away in December 1996 at the age of 62, and was buried in New York (Lakeview Cemetery, Ithaca) right beside his parents.

An astronomer, philosopher, professor and NASA consultant, Carl Sagan won 30 public awards, published over 600 scientific articles and authored or co-authored 20 books. I’ll never weary of recommending Pale Blue Dot to anyone who will listen!  The unmanned Mars Pathfinder spacecraft was renamed the Carl Sagan Memorial Station in 1997. Asteroid 2709 Sagan is also named in his honor.

Sagan was instrumental in the early Mariner missions to Venus, determined landing sites on Mars for the Viking Lander probes, and also assembled the first physical messages sent into space.  He was instrumental in establishing the Search for Extraterrestrial Intelligence (SETI), urging the use of radio telescopes to detect signals from other intelligent life. Along with Frank Drake, he also composed the Arecibo message, beamed once into space in 1974.

He's one of those people who makes you scratch your head and think, "What the heck have I been DOING with my time?!"

Carl had the ability to make space "knowable" to audiences of all ages. He was known for popularizing  science in a way that inspired people to understand both our insignificance in the larger universe, but also, paradoxically, the absolutely precious nature of our enormously unlikely existence.
