»The Cambridge/Caltech team (...) surpassed the
quality of images taken from space by using a high-speed
camera to take numerous images of the same stars at a rate
of 20 frames per second. Because of fluctuations in the
atmosphere, some of these were less smeared than others.
The team then used computer software to choose the best
images, and these were combined to create pictures far
sharper than anything that has been taken from space.«

Auf dem Paranal erzeugt man mit einem Laserstrahl
einen künstlichen Stern. Dessen Verzerrungen werden
verwendet, um eine adaptive Optik so einzustellen,
daß die störenden Effekte der Luft herausgerechnet
werden können.

Heute kam eine Meldung, daß man nun per Netzwerk (1 Gb/s)
ein Radioteleskop von planetarischen Ausmaßen
realisiert hat.
