crazy article at astrobiology magazine about using a cloud of space gas as a lens for what amounts to a natural telescope fifty light-years long, and using that telescope to peer into a black hole four billion light-years from earth. oh yeah, and there is a quasar mixed up in it all for good measure. evidently it will be the most powerful telescope ever gazed through. to quote: “the new technique promises researchers the ability to resolve details about 10 microarcseconds across - equivalent to seeing a sugar cube on the moon, from earth. neat-o.
