"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.

Barred and twisted

A shot of NGC 7479 from Whiting NJ. Gene just fell a tree that was blocking a large part of his Eastern sky. The tree was sacrificed in the name of astrophotograpy, even though Gene claims otherwise. This image was taken from a nearby patch of grass.   The image is an LRGB composite for a total of 1/2 hour exposure through a 5" f7 refractor.This galaxy is also known as Herschel 55-1. Here is a blurb from Wikipedia:   NGC 7479 is a barred spiral galaxy discovered by William Herschel in 1784, about 105 million light-years away. Supernovae SN 1990U and SN2009jf occurred in NGC 7479. NGC 7479 is also recognized as a Seyfert galaxy undergoing starburst activity in the nucleus and the outer arms (Kohno, 2007 ). Polarization studies of this galaxy indicate it recently underwent a minor merger and that it is unique in the radio continuum with arms opening in an opposite direction to the optical arms (Laine, 2005).
