This Week's Sky at a Glance, June 2 – 11
Venus shining in the dusk says goodbye to Pollux, hello to Mars. . . which is busy crossing the Beehive Cluster. Arcturus stands straight over Spica after dark, and Kochab stands straight over Polaris, it's that time of year.
This Week's Sky at a Glance, May 26 – June 4
Venus starts the week under Pollux and Castor, then lines up with them. Nearby, Mars steps on the Beehive. In the south the Bootes kite flies high.
This Week's Sky at a Glance, May 19 – 28
As Venus and Mars move toward each other in the western dusk, Venus brightens and Mars shrinks — just like they always do. This week the waxing Moon hops over both.
This Week's Sky at a Glance, May 12 – 21
Mars and Venus each line up with a pair of stars this week. And with the Milky Way lying all around the horizon, the Coma Berenices Star Cluster floats overhead.
This Week's Sky at a Glance, May 5 – 14
Big, macho Venus is closing in on wimpy little Mars in the western sky at dusk. Venus says hi to M35 on the way. In early dawn, the waning Moon guides the way to Saturn.
This Week's Sky at a Glance, April 28 – May 7
The Arch of Spring across the west enfolds Mars and Venus. Wintry Sirius nears its heliacal setting low in the southwest. The Summer Triangle stars come into view one by one in the east.
This Week's Sky at a Glance, April 21 – 30
The Moon hops past Venus and then Mars. Hydra snakes up, the Pointers point down, and the Arch of Spring spans the west.
This Week's Sky at a Glance, April 14 – 23
Venus shines with Aldebaran and the Pleiades in late twilight. After sunset on the 20th, try to spot your record-breaking thinnest young Moon. And Leo walks west with a mouse-galaxy dangling from his chin.
This Week's Sky at a Glance, April 7 – 16
Venus in the western twilight guides the way down to Mercury. The Pleiades pass by Venus far in its background. And can you find the head of Hydra?
This Week's Sky at a Glance, March 31 – April 8
Mercury emerges this week far below Venus at dusk, while Venus makes its way toward the Pleiades. Orion turns his belt horizontal for the warming weather.
This Week's Sky at a Glance, March 24 – April 2
The Winter Hexagon fills the west after dark. The waxing Moon steps east across the evening sky from Venus past the Pleiades, then past Mars.
This Week's Sky at a Glance, March 17 – 26
The crescent Moon visits Venus. The Orange Triangle turns nearly equilateral. And as evening grows late, Arcturus begins to dominate the low northeast. It's turning spring.
This Week's Sky at a Glance, March 10 – 19
Venus and Jupiter widen in twilight. Mars, Aldebaran, and Betelgeuse form a triangle of similar orange sparkles. And there's lots to explore with optical aid off the trailing foot of Gemini, including the Toes.
This Week's Sky at a Glance, March 3 – 12
Venus and Jupiter draw majestically apart in the evening twilight, 1° farther each day. Much higher, Mars makes its third pass in the last five months between the horntip stars of Taurus.

Venus and Jupiter, the two brightest celestial objects after the Sun and the Moon, shine together in the western twilight before, during, and after their March 1st conjunction.

Venus and Jupiter put on a dramatic show in twilight, as they creep toward each other for a March 1st conjunction. The crescent Moon passes though, almost kissing Jupiter on Wednesday the 22nd.
This Week's Sky at a Glance, February 10 – 19
Comet ZTF is fading and receding into the distance. On the other hand, it's now conveniently placed high overhead in early evening in a moonless sky; the waning Moon doesn't rise until late.
This Week's Sky at a Glance, February 3 – 12
Comet ZTF is still near its brightest, moonlight and all. Around the Big and Little Dog Stars, trace out the stick-figure patterns of the big and little dogs. A ghostly unicorn haunts the inside of the Winter Triangle.
This Week's Sky at a Glance, January 27 – February 5
Comet ZTF is at its best this week — but every night moonlight encroaches on the scene until a later and later hour. Along the way, the Moon occults Mars for the southern U.S. and again forms isosceles triangles with naked-eyestars.
This Week's Sky at a Glance, January 20 – 29
Venus and Saturn have a close conjunction in twilight. Comet ZTF heads into its best week. And Betelgeuse overtakes Sirius ever earlier in the night.
