Buckle up, friends—this is not your average jigsaw. If you're into outer space, you'll not only appreciate that this puzzle is based on a photo from the Hubble Space Telescope that shows stars being born in the Carina nebula, but also , much like the endless abyss that surrounds us, it has no fixed shape, no starting point, and no edges. Limitless combinations are possible, and that's exactly the fun of it. Handmade by Jessica Rosenkrantz and Jesse Louis-Rosenberg in New York.
