Sometimes Earth was the gravitational master as in October 2013, when the probe flew by our…

Spectacular Mother’s Day Aurora!

I was about to go to bed last night (May 7) when I made the fateful decision to crack the door for a last look at the sky. A single arc of aurora lit up the northern sky. Instead of hugging the pillow, I gathered camera and tripod and made a short drive to a…
