Night Sky

Night Sky

Night Sky

After picking Dorothy up at Julia’s house this evening, I set my camera on the roof of the car, told Dorothy to sit still, and fired off a 30 second exposure. The clouds were moving fairly quickly so they have ended up blurred and covering more of the sky than was apparent when I took the picture. Also, the spinning of the earth turned each pin point star into a little line segment. I think it’s really cool that here at a latitude of 39° we’re moving at over 800 miles per hour as we spin around the earth’s axis. For course that doesn’t count the 66 thousand miles per hour we’re hurtling through space as we orbit the sun. Anyway, during a 30 second exposure the earth turns one eighth of a degree. Hopefully that doesn’t make you dizzy. If you prefer, you can think of this as a pretty picture of the night sky. That works for me.
