Starting on Wednesday night, look up at the sky and you might see a the moon in a four-night cosmic dance with Mars, Saturn, and the bright star Regulus.
The moon will take center stage in a cosmic dance with Mars, Saturn and the bright star Regulus this week during a four-night sky engagement that begins May 19.
The celestial sky show will appear in the southwestern night sky (weather permitting) beginning around nightfall, according to the astronomy magazine StarDate. This sky map shows where to look this week to spot the moon, Regulus, Saturn and Mars.
On Wednesday, May 19, Mars will appear above the moon while the bright star Regulus shines to the left and above Mars. The red planet will actually look like a bright orange star, StarDate reported in a skywatching alert.
Regulus is the brightest star in the constellation Leo (The Lion) and is more massive, hotter and brighter than our sun, StarDate reported.
On Thursday, Regulus can be found to the upper right of the first-quarter moon, which will grow steadily fatter and fuller as the week wears on. Mars will appear further off to the moon's right. [Full moon photos.]
Together, the moon, Mars and Regulus will form a skinny triangle in the night sky until about 2 a.m. local time, when they sink below the horizon.
Saturn will make its first appearance with the others on Friday, May 21 and should stand out in the due south direction of the sky.
