OBSERVING
August 2020

1 DAWN: Kick the month off by
finding Venus and Zeta (ζ) Tauri shining
less than 2° apart. While you're at
it, look lower left of this pair to espy
Mercury rising in the east-northeast,
shepherded by Pollux to its upper left.
The planet and the star remain within
7° of each other the next two mornings.
1 DUSK: The waxing gibbous Moon,
Jupiter, and Saturn form a triangle
above the southeastern horizon. The
following evening, the Moon teases
itself away from the gas giants and the
three celestial bodies rearrange into a
graceful arc.
9 MORNING: Only about 1°
separates the waning gibbous Moon
from Mars. Catch this sight before the
rising Sun washes it away.

11-12 ALL NIGHT: This year's
Perseid meteor shower peak coincides
with a last-quarter Moon that rises
around midnight. But meteors will start
appearing earlier in the evening, so
head out after sunset. The Perseids
are a notoriously long shower, and you
should see meteors any time after midJuly and well into the second half of
August (see page 48).
13 MORNING: The waning lunar
crescent rises in tandem with
Aldebaran, the Eye of the Bull, with less
than 4° separating the two.
15 DAWN: Look to Gemini, the Twins,
to see the slender Moon and Venus
lying a little more than 3° apart. Castor
and Pollux mirror the Moon and the
planet to their lower left.

S This Hubble image of the Lagoon Nebula (M8) highlights delicate wisps of nebulosity that
are colored according to filter used: Light from glowing hydrogen is red, while that from ionized
nitrogen is green. On really dark nights you might catch the Lagoon without optical aid near the
Teapot asterism in Sagittarius - take your binoculars out for a closer look at this fuzzy patch.
(See page 20 for more on this intriguing object.) N AS A / E S A

22 DUSK: Find the waxing
crescent Moon slightly more than
5° from Spica, Virgo's brightest
star. Watch as the pair sinks toward
the horizon in the ever-deepening
twilight.
25 DUSK: The first-quarter Moon
gleams in Scorpius some 5° to 6°
from the smoldering supergiant
Antares, the heart of the Scorpion.
27 DUSK: As the Moon pays its
second visit to Jupiter and Saturn
this month, the three form a line
above the southern horizon.
28 DUSK: The waxing gibbous
Moon nestles up to Jupiter and
hangs some 2° below the gas giant,
with Saturn to the pair's left.
29 DUSK: The fattening Moon has
leapfrogged over Saturn, and the
three orbs now form a graceful arc.
