The Sky This Week for August 23 to August 28
Planets, Pallas, and the Big Dipper will all make wonderful viewing this week.

Tuesday, August 23
• The three evening planets form a pretty isosceles triangle above the western horizon tonight. Jupiter stands highest and lies some 4° from both Mercury and Venus, while the two inner planets appear 6° apart.
• The western twilight vista isn’t the only exciting one happening this evening. As those three planets set, shift your gaze about 25° above the south-southwestern horizon. There you will find fiery Mars flanked by golden Saturn some 4° above it and ruddy Antares 2° below it. The two bright planets form a straight line with the 1st-magnitude star tonight.

• Last Quarter Moon occurs at 11:41 p.m. EDT. It rises around midnight local daylight time and climbs high in the southeast by the time twilight starts to paint the sky. Earth’s only natural satellite lies next to the Hyades star cluster in the constellation Taurus the Bull.

• Mars passes 4° due south of Saturn today. The Red Planet shines twice as bright as its ringed companion, and the two make a stunning pair with the naked eye and through binoculars. Both are worth examining through a telescope as well. Mars’ sports an orange-red disk that spans 11″ and shows several subtle dark markings. Saturn measures 17″ across while its dramatic ring system stretches 38″ and tilts 26° to our line of sight.

• Distant Neptune reaches opposition and peak visibility one week from today, but the view now is essentially the same. The ice giant planet rises during evening twilight and climbs nearly halfway to the zenith in the southern sky by 1:30 a.m. local daylight time. The magnitude 7.8 planet lies in Aquarius, 1.1° southwest of 4th-magnitude Lambda (l) Aquarii. You’ll need binoculars to spy Neptune and a telescope to see its blue-gray disk, which spans 2.4″.
Saturday, August 27
• Venus and Jupiter lie closer to each other today than at any time since May 2000. At their tightest, just 4.2′ separate them. Unfortunately, this happens in late afternoon from North America. By twilight, the two worlds have pulled slightly apart — 5.5′ from the East Coast and 12.1′ from the West Coast. Still, that’s close enough that many people will see the two merge into one. Binoculars will provide spectacular views, clearly splitting the pair and revealing Mercury 5° to their lower left and just above the horizon. Most telescope-eyepiece combinations will show Venus and Jupiter in the same field, with Jupiter spanning 31″ and Venus 11″.
Sunday, August 28
• Evenings this week are great times to explore the constellation Sagittarius the Archer. This star group lies due south and at peak altitude around 9 p.m. local daylight time, just as the last vestiges of twilight fade away. The brightest stars within the constellation form the shape of a teapot — a distinctive asterism once you’ve found it. The central regions of the Milky Way pass through Sagittarius, so it’s always worth exploring the area through binoculars or a telescope.
