The Galilean Moons

A few months ago, I posted a grainy photo of the International Space Station which I took with my iPhone 5S. But it seems my dad has outdone me in the field of amateur space photos taken with a phone camera.

Dad put his Samsung Galaxy S4 up to the eyepiece of his telescope the other night and snapped this picture of Jupiter.

The four Galilean moons can be clearly seen on either side of the planet – Io, Europa, Ganymede, and Callisto. What captivates me about this photo is how they are so evenly spaced around Jupiter – he couldn’t have taken the photo at a better time. I imagine this is what Galileo saw when he first raised his telescope to the stars.

Well done, Dad.
