Callisto Transits Jupiter

Sometimes you have to be at the right place in the Universe at the right time.

Early on the morning of August 4th, 2008 despite a thick summer haze I captured this fuzzy image of the great gas planet Jupiter just as the Jovian moon Callisto was crossing in front of the planet. The moon appears as a black dot at the upper right edge and the shadow of Callisto can be seen on the face of the planet just above the image of Callisto. The haze-bloated dot to the left of Jupiter is the moon Io and the moon Ganymede appears to the right of the planet. -- Dalton Hammond
