Be sure to tip your stovepipe hat today in honor of the 200th anniversary of the birth of Abraham Lincoln. "Honest Abe" has become one of the most iconic U.S. presidents, revered in countless monuments and other honors.
Among them happening today is the official release of the first of four redesigned one-cent coins. Four new scenes will replace the view of the Lincoln Memorial in Washington, D.C., that has graced the back of the penny for the past 50 years. Two of them are pictured here; to see the others, visit the U.S. Mint (or watch your news tonight).
Lincoln's life has been well documented with numerous biographical accounts. It turns out that some tales have an astronomical bent. If you've been a long-time reader of Sky & Telescope, you probably know of them from articles written by Donald Olson and his colleagues.
The March issue of S&T now available on newsstands includes an article by Olson and Laurie Jasinski that summarizes several celestial connections to our 16th president. Click through to the Beyond the Printed Page article to find links to a pair of Olson's articles about Lincoln as well as another tidbit of Lincoln lore that didn't fit into the March issue.
Today also marks the 200th birthday of Charles Darwin, so you might also want to help celebrate Darwin Day with the rest of the world.
