Welcome to the Milky Way Explorer

Welcome to the Milky Way Explorer, a guided trip through our spiral Galaxy and its neighborhood. You choose where to explore, and a radio astronomer talks to you about each stop. The many experts you will meet along your tour are the real people who have helped us better understand the wonders of our Milky Way Galaxy.

We built this Explorer in time to share with you some exciting science: a cloud of gas is falling into the supermassive black hole in the center of our Galaxy right now! Join this once-in-a-lifetime event by exploring the center of our Galaxy stops on this tour. We will update those stories as we learn more, and we will also add more stops on your tour, so keep checking in for the latest additions.
