Jupiter and the Galilean Moons, April 2015

Jupiter is well-placed for viewing during April 2015. It is in the constellation Cancer all month and can be spotted in the evening sky.

On Saturday and Sunday, you can finish the day by stepping outside and enjoying a view of the rendezvous of two of the brightest objects in the night sky — the moon and the planet Jupiter.

About 45 minutes after the sun sets on both nights, the eye-catching celestial duo will be visible in the southwest sky, roughly two-thirds of the way up from the horizon to the point directly overhead (called the zenith).

The moon will officially reach first-quarter phase on Saturday evening (April 25) at 7:55 p.m. EDT (2355 GMT). The terminator — the line separating the light half of the moon (on the right) from the dark half — will appear perfectly straight, and Jupiter will be about 9 degrees above and to the left of the moon’s left. (Reminder: Your clenched fist held at arm’s length measures about 10 degrees.)
