Note: No screencap does the thing justice, you're gonna just have go to the website and click around playing space ranger on your own. Clicking the 'Take a Tour' button in the upper left corner is a good start though.
100,000 Stars is a website with a 3-D interactive map of the Milky Way Galaxy you can zoom in and out of to explore our little neck of the universe. Fun fact: did you know that Voyager 1, the furthest-from-earth man-made object, is only a scant 17-light hours away? That's not very far in the grand scheme of things, but still way further than I could swim without cramping up and drowning. Now get out there and claim yourself a star! Just a heads up though: I got like four bought for me as birthday presents when I was a kid so those ones are off limits.
Thanks to PORKINS, who tried to claim the whole galaxy WHICH IS AGAINST THE RULES.
