Today:
Between 5:30 and 6 PM, look about halfway up in the northeastern sky. Here lies a constellation within which Perseus hold he head of the Medusa in his left hand; in the Medusa’s right eye shines the binary star Algol, “The Ghoul”. Between 7:44 and 9:44 PM, Algol reaches its minimum brightness, when the fainter of its two stars eclipses the brighter star.
Friday:
Looking due east, two-thirds of the way up from the horizon at 5:30 PM, the middle star of Andromeda marks her waist, joined by a star of similar brightness to the upper right for her head, and another marking her foot to the lower left. Follow two fainter stars up from her waist to find a faint smudge of light, the Andromeda Galaxy.
Saturday:
As the evening twilight fades between 5 and 5:30, the waxing Gibbous Moon is apparent in the southeast. To its right, nestled among the faint stars between the constellation Aquarius to the right, and Picses to the left, glows the planet Saturn, famous for its broad, icy band of rings, only visible in telescopes. Saturn appears to slide just to the right of the Moon as they track across the southern sky, but it is the Moon actually tracking east, moving away from Saturn.
