Five Star Gift Ideas

How about getting him a Galileo telescope? This would allow him to explore the night sky and get a closer look at stars and planets, just like Galileo did. You could also get him a Galileo biography book so he can learn more about his life and his contributions to science. Or, if your husband enjoys puzzles, you could get him a Galileo puzzle, featuring one of his famous scientific illustrations or discoveries. Another idea could be visiting a nearby observatory or planetarium together to celebrate his birthday.

Or you can get him a star map with the date when he was born.

“It was such a sentimental and romantic present for my husband's birthday (since he is so into astronomy and the moon on the background). The order came super well packaged, and now it is the gem in the basement :)”
