"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.

El Sol

Here's a photo of the sun.  I had an impossible time finding a perfect focus.  I used a Celestron SP-C6 telescope and an Olympus C-4040Zoom.  I was very impressed with the Thousand Oaks Solar Filter.  The RG film is great.  I used to use Roger Tutthill's solar filter.  Oaks is a more natural color instead of blue.

Solar Fireworks

4th of July Sunspots

Looks like there's a nice sunspot group on the Sun -- some nice solar fireworks for the 4th of July! Biggest group I've seen in quite sometime. It is right on the meridian.

Sunspots

Note a group of small sunspots have just come onto the disk. They're not visible to the naked eye but might be nice with a white light or H-alpha filter.
