Bright, large evening planets and a low, morning beacon help celebrate the golden anniversary of Apollo 11 and its leap into history.
When the sun sets in the west, Jupiter is high in the southeast in the early evening, looking snazzy at -2.6 magnitude now, quite bright. As the night darkens, find the reddish star Antares (a first-magnitude double star) to the large planet’s right.
Saturn follows Jupiter to ascend the southeast sky in the evening. The ringed planet is at opposition July 9, which means that the sun is opposite the giant Saturn — from our own earthly perspective, according to the Naval Observatory. In other words, instead of a full moon, we’re looking at a full Saturn.
The ringed planet’s opposition means we can see it all night, and from late June through late July, Saturn is a bright zero magnitude — chilling in the constellation Sagittarius — throughout the heart of summer.
A fattening gibbous moon approaches Jupiter on July 12, passing the large planet July 13. The plump moon hugs Saturn on July 15 and passes it by July 16 — when the moon is full to coincide with the 50th anniversary of the Apollo 11 launch.
The South Pacific, Chile and Argentina can enjoy a four-minute total solar eclipse July 2. San Francisco’s Exploratorium (exploratorium.edu/eclipse) teams with the National Science Foundation to offer a video stream of it from 4 to 5 p.m. Eastern time. This total solar eclipse cannot be seen from the United States.
The partial lunar eclipse July 16 is good for observers in Europe, Africa and South Asia, according to eclipse expert Fred Espenak (mreclipse.com). North America will completely miss it.
