This video illustrates the place of Eos—a newly discovered molecular hydrogen cloud that is 99-percent CO dark—on the edge of the Local Bubble, a large gas-filled cavity that encompasses the solar system. It is the nearest molecular cloud to earth at only 300 light years away. Scientists estimate that Eos is vast in projection on the sky, measuring about 40 moons across the sky, with a mass about 5,400 times that of the sun.
