Looking Directly at Extrasolar Planets
D2Deek writes "Science Daily is reporting on a new device called an Optical Vortex Coronagraph that's been invented to directly image planets orbiting other stars by using a special lens that "spins out" the light from the star leaving only the reflected light from the planet." I just can't imagine trying to clean a lens shaped like a giant corkscrew.
Do not look directly at extrasolar planets with remaining good eye.
Dark Reflection
Is that anything like the Total Perspective Vortex ??
try { do() || do_not(); } catch (JediException err) { yoda(err); }
I just can't imagine trying to clean a lens shaped like a giant corkscrew.
Just run a lint-free Debian logo through it a couple of times.

It's worth RTFA just to see a reference to "Foo et al."
(The full paper title is "Optical Vortex Coronagraph" by Gregory Foo, David M. Palacios, Grover A. Swartzlander Jr., College of Optical Sciences, University of Arizona).
"How to Do Nothing," kids activities, back in print!
"As Gilman looked into the Optical Vortex Coronagraph at the extrasolar planet, he became conscious of some formless alien presence watching him with horrible intentness. He felt entangled with something -- something which was not in the telescope, but which had looked through it at him. Something which would ceaselessly follow him.
"Cautious investigators will hesitate to challenge the common belief that Gilman was killed by lightning, or by some profound nervous shock derived from an electrical discharge. Archaeologists and astronomers, however, are still trying to explain the bizarre designs impressed on the special helical-shaped mask, whose inner side bore ominous stains."
