On April 17 to 19, you'll see some gorgeous pairings of the moon and brightest planet Venus. You'll find them in the west shortly after the sun goes down.
Mercury is starting its best morning appearance for 2018 for the Southern Hemisphere. Northern Hemisphere? You might catch the moon on April 13 (maybe 14), but Mercury will be tougher to see.
The last quarter moon you'll see late tonight is aligned with 2018's closest apogee, that is, the closest of the moon's farthest points in its monthly orbit. And that's no surprise ...
These 3 worlds - the moon, Mars and Saturn - will climb over your horizon very late at night this weekend. You can see all 3 together before dawn Saturday and Sunday.
Stay up late Tuesday, or get up early Wednesday morning, to catch the moon and Jupiter. From the time they rise until the sun comes up, they'll be the brightest objects in the sky.
