See the crescent moon shine beside blue star Spica at sunset on July 30

An image of the moon close to its first quarter phase, with most of its right-hand side lit by direct sunlight. Dark lunar seas can be seen close to the equator.

Don't miss the waxing crescent moon shine alongside Spica and the stars of the constellation Virgo in the hours following sunset on July 30.

Look 20 degrees above the southwestern horizon in the hour following sunset on July 30 to find the waxing crescent moon — now 32% lit — hanging in the evening sky, with Spica shining as a bright point of light less than 4 degrees to the upper left of the lunar disk. Remember, the span of your clenched fist held at arms length is approximately 10 degrees in the night sky, while the tip of your little finger measures roughly 1 degree!
