Royal Planets Rule the Evening Sky, the Waning Moon meets Mars, See Stars’ Colours, and more Meteors!

(Above: the double star Albireo is a favorite of summer star parties, and a perfect way to see the colour differences between stars of different surface temperatures. The brighter yellow star has a temperature of 4400 K, while the blue star is almost three times that. Both stars are about 380 light-years from the sun.)
(Above: The western evening sky, shown here at 9:20 pm local time, features Castor and Pollux flanked by yellow Capella and reddish Betelgeuse, and white Procyon. The colour contrasts are visible in unaided eyes. Look for Sirius low in the SW.)
(Above: The eastern evening sky, shown here at 9:30 pm local time, features bright orange-tinted Arcturus. Regulus and Spica are prominent in the southern sky. Later in the evening, bright white and very hot Vega will rise in the east.)

(On the evening of Sunday, April 29, shown here at 9:45 pm local time, Venus will appear to the right of the triangular face of Taurus the Bull, and its bright orange-tinted star Aldebaran. Venus will climb higher every evening while Taurus slowly descends into the twilight.)
Above: Bright Jupiter will rise before 9 pm local time this week, and Saturn and Mars will join it after 1 am. On Saturday morning, May 5, the last quarter moon will land between the two morning planets, as shown here at 2:30 am local time.
Mercury is teasing northern hemisphere observers recently as it skirts the eastern pre-dawn sky, shown here at 5:30 am local time. On Sunday, April 29, the elusive planet reached it widest angle west of the sun. The ecliptic (green line) will tilt higher over the next weeks, lifting Mercury higher while it descends sunward.
The Eta-Aquariid meteor shower, which peaks Saturday morning, May 5, puts on a better show for Southern Hemisphere observers because Aquarius is low in the sky for northerners.
