Astronauts Discover "Bone" of Gas and Dust in Milky Way
300 light years long, 1 or 2 light years wide
Astronomers have spotted a new component of the Milky Way galaxy's skeleton — a "bone" of dust and gas that contains about as much material as 100,000 suns.
The newfound Milky Way bone is more than 300 light-years long but just 1 or 2 light-years wide, giving it the appearance of a slender cosmic snake, researchers said.
