"Professor Goddard does not know the relation between action and reaction and the need to have something better than a vacuum against which to react. He seems to lack the basic knowledge ladled out daily in high schools."
--1921 New York Times editorial about Robert Goddard's revolutionary rocket work.

"Correction: It is now definitely established that a rocket can function in a vacuum. The 'Times' regrets the error."
NY Times, July 1969.

Dumbbell nebula overhead

Whiting NJ is not exactly New Mexico, but the skies are certainly darker than Montclair and it shows. This is a 5 minute shot of the dumbell with a one hour luminance in h alpha.

Filters and CCD camera allow us to image from our light polluted skies, but nothing can substitute for a darker sky. What a shame we are losing our night skies.
