Let's make this birthday one to remember.

80 years old (Born on November 02, 1944)

Happy Birthday, Jeffrey A. Hoffman! To the man who's boldly gone where few have gone before—and did it with style—the universe probably still owes you a big thank-you for fixing Hubble's blurry vision. Without your timely spacewalk repairs, we'd all be squinting through fuzzy star pics and mistaking Saturn for a cosmic doughnut.

As only the second Jewish astronaut in space, you've surely earned bragging rights at every Hanukkah gathering forever. Here's hoping this birthday is as stellar as your missions aboard NASA shuttles—filled with laughter, insight and maybe just one gravity-defying slice of cake! Mazel tov!
