Invisible Space 'Noodles' May Lurk in the Milky Way

Invisible "plasma lenses" shaped like noodles, lasagna sheets or hazelnuts might lurk between stars in the Milky Way, researchers say. This finding could help solve the longstanding mystery of where a major part of the galaxy's matter is hiding, the scientists added. Quasars are the most energetic form of active galactic nuclei, which are supermassive black holes in the centers of distant galaxies that release extraordinarily large amounts of light as they rip apart stars and gobble matter.
