Observatory Aligned with Moon Occulting Jupiter
Explanation: Sometimes we witness the
Moon moving directly in front of -- called occulting -- one of the planets in our
Solar System.
Earlier this month that planet was Jupiter.
Captured here was the moment when
Jupiter re-appeared from
behind the surface of our Moon. The Moon was in its
third quarter, two days before the dark
New Moon. Now, our
Moon is continuously half lit by the Sun, but when in its third quarter, relatively little of that half can be seen from the
Earth. Pictured, the Moon itself was aligned behind the famous
Lick Observatory in
California,
USA, on the summit of
Mount Hamilton.
Coincidentally, Lick enabled the discovery of a moon of Jupiter:
Amalthea, the last visually detected moon of Jupiter after
Galileo's
observations.

If my eyes aren't deceiving me, there's a faint dot on the top right of Jupiter, my guess is it's Ganymede.. There's another even fainter dot on top right of the first dot, and I think it must be Callisto.
Or is it just my eyes tricking me???

You are correct! Both Ganymede and Callisto are visible in the image

From the description: "Now, our Moon is continuously half lit by the Sun"
Is that accurate? Doesn't the Earth block some Sunlight from hitting the moon during a lunar eclipse? Or is my 3D sense kaput once again?

Small correction. The Moon is well past Third Quarter in the photo. The Third Quarter is when the visible hemisphere of the waning Moon is half illuminated.

I guess no one wanted to take lunar eclipses into account
