Explanation:
Fainter stars in the zodiacal constellation Capricornus are
scattered near the plane of
the
ecliptic
in this field of view.
The two brightest ones at center aren't stars at all though, but
the planets Mars and Saturn.
Taken on the morning of April 4, the
telescopic
snapshot
captured their tantalizing
close
conjunction
in a predawn sky, the pair of planets separated
by only about 1/3 of a degree.
That's easily less than the apparent width of a Full Moon.
Can you tell which planet is which?
If you guessed Mars is the redder one , you'd be right.
Above Mars, slightly fainter Saturn still shines with a
paler yellowish tinge in
reflected sunlight.
Even at the low magnification, Saturn's largest and brightest
moon Titan can be spotted hugging the planet very closely on the left.
