But there's billions of stars out there — how complex would that map need to be? Actually, Samuel Arbesman, a research fellow from Harvard, has come up with a fun solution. He created the 'Milky Way Transit Authority (MWTA),' a simple transit system in the style of the iconic London Underground 'Tube Map.' (Travel Tip: Don't spend too much time loitering around the station at Carina, there's some demolition work underway.)"
