Incredible technology: How to see an invisible black hole
Black holes are essentially invisible, but astronomers are developing technology to image the immediate surroundings of these enigmas like never before. Within a few years, experts say, scientists may have the first-ever picture of the environment around a black hole, and could even spot the theorized "shadow" of a black hole itself.

Squinting At Saturn Through 17th Century Technology
(ISNS) -- A team of French researchers has shed light on an important moment of astronomical history by testing the old lenses used by astronomer Jean-Dominique Cassini when he observed a minuscule gap between two of Saturn's rings in 1675. Questions have lingered over whether it was possible to see this gap, which was later named the "Cassini Division," with the optics he had at his disposal.
