This week, Voyager 1 just became the first man-made object to leave our solar system and enter into inter-stellar space. Sounds pretty impressive, right? It is, especially when you factor in that it did this using technology less advanced than that found in your iPhone and is decades-old.
In honor of this, we're celebrating with a special Friday beefcake...in space! We've gathered up some of our favorite aliens, astronauts, and other space travelers to help celebrate. Include your own favorites in the comments and let star-studded swooning begin!
