This Week's Sky at a Glance, October 27 – November 5
The full Moon on October 28th shines near full Jupiter at opposition this week. Telescopically, Jupiter this week is as big as you'll ever see it,
This Week's Sky at a Glance, October 20 – 29
The waxing Moon in the evening sky visits Saturn, then Jupiter. And as Halloween approaches, Arcturus becomes the Ghost of Summer Suns.
This Week's Sky at a Glance, October 13 – 22
The week's big event is the Moon stepping on the Sun on Saturday the 14th. But the Moon's not done. Several days later it steps squarely on the handle of the Sagittarius Teapot, then on Herman's Cross. Show-off. Image: S&T's Sean Walker resolves Io half lit as it slips into Jupiter's shadow.
This Week's Sky at a Glance, October 6 – 15
A partial/annular eclipse of the Sun washes across the Americas on Saturday the 14th. Four days before, the waning Moon and Venus pair up in early dawn with Regulus glimmering between them.
This Week's Sky at a Glance, September 29 – October 8
The Moon pairs with Jupiter, then the Pleiades, as it departs the evening sky. That leaves a dark-sky Milky Way crossing the zenith, where Cygnus the Milky Way Swan flies southward for fall.
This Week's Sky at a Glance, September 22 – October 1
The bright Moon steps eastwaed night by night under Altair, then Saturn, then the Great Square of Pegasus. Meanwhile, Deneb replaces Vega as the zenith star; welcome to fall.
This Week's Sky at a Glance, September 15 – 24
Comet Nishimura shines at its brightest... but don't be disappointed, we warned you. Meanwhile Jupiter outdoes Saturn as an evening light, and the Little Dipper dumps water into the Big Dipper.
This Week's Sky at a Glance, September 8 – 17
Comet Nishimura teases us shyly low on the dawn horizon, then low on the dusk horizon. The Milky Way arches high across the evening sky, and Saturn invites your telescope.
This Week's Sky at a Glance, September 1 – 10
Vega culminates at the zenith around the end of twilight. Arcturus and the Dipper sink through the evening. Saturn and Jupiter rule the late-night hours, and Venus shines at dawn.
This Week's Sky at a Glance, August 25 – September 3
Saturn comes to opposition. Vega crests at the zenith, while Arcturus declines in the west. Venus shines at dawn. Go out before dawn's very first light, and you get an Orion-starring preview of the evening sky at New Year's.
This Week's Sky at a Glance, August 18 – 27
The waxing Moon passes Spica and then will occult Antares for much of North America. Saturn reaches opposition this week. The Andromegasus Dipper scoops up as summer wanes.
This Week's Sky at a Glance, August 11 – 20
The Perseid meteors come rushing in, and peak Perseid night ends with the waning crescent Moon triangulating Castor and Pollux. Vega and Sagittarius culminate after dark. Scorpius lays itself down.
This Week's Sky at a Glance, August 4 – 13
We're approaching the peak of the Perseid meteors. Vega claims the zenith as the Teapot claims the south. In twilight, Mars has a friendly but not very intimate date with Mercury.
This Week's Sky at a Glance, July 28 – August 6
Venus turns super-interesting and then disappears. Mercury lingers behind it in twilight. So does little Mars in third place. On the other side of the sky, the Moon passes Saturn.
This Week's Sky at a Glance, July 21 – 30
Low in twilight, Mercury consorts with Venus and squeaks by Regulus. The waxing gibbous Moon does what it does every July: crosses Scorpius and Sagittarius.
This Week's Sky at a Glance, July 14 – 23
Venus, Mercury, and Mars, very unequal, gather low in the western twilight with the crescent Moon stepping over them and Regulus in their midst. And do you know which way the Kite of Boötes bends?
This Week's Sky at a Glance, July 7 – 16
Mars meets Regulus while Venus looks on. Scorpius comes to its July height — bearing its double stars, Cat's Eyes, and Little Cat's Eyes. And keep a lookout for noctilucent clouds at the end of dusk.
This Week's Sky at a Glance, June 30 – July 9
Full Moon in the Teapot. Are the colors of brights easier to discern in moonlight? Twilight? Mars closes in on Regulus as Venus watches. And the supernova in the Pinwheel Galaxy is still 12th magnitude.
This Week's Sky at a Glance, June 23 – July 3
Venus almost meets Mars in the western twilight, then runs away. Vega and Arcturus become equally balanced across the zenith. Down from Vega hangs the Summer Triangle.
This Week's Sky at a Glance, June 16 – 25
Venus and Mars are getting closer together in the western dusk. And why does Mars always turn so puny when it approaches Venus? The "Betelgeuse of Summer" is up, and the Little Dipper stands on end.
