Wandering
through the constellation Sagittarius,
bright planets Mars and Saturn appeared together
in early morning skies over the
last
weeks.
They are captured in this 3 degree wide field-of-view from March 31
in a close celestial triangle with large globular
star
cluster Messier 22.
Of course M22 (bottom left) is about 10,000 light-years distant,
a massive ball of over 100,000 stars much older than our Sun.
Pale yellow and shining by reflected sunlight, Saturn (on top) is
about 82 light-minutes away.
Look carefully and you can spot large moon Titan
as a pinpoint of light at about the 5 o'clock position in the glare
of Saturn's overexposed disk.
Slightly brighter and
redder Mars
is 9 light-minutes distant.
While both planets are moving on toward upcoming oppositions,
by July Mars will become much
brighter still,
with good telescopic views near its 2018 opposition.
Then it will be a mere 3.2 light-minutes from planet Earth.
