Explanation:
A telescopic tour of the
constellation
Sagittarius offers the many
bright clusters and nebulae of
dimensioned space in a
starscape
surrounding the
galactic center.
This gorgeous
color
deep-sky photograph visits two such lovely sights,
cataloged by the 18th century cosmic tourist
Charles
Messier as M8 and M20.
M20 (upper left),
the Trifid Nebula, presents a striking contrast in
red/blue colors and dark dust lanes.
Just below and to the right is the
expansive, alluring red glow of M8,
the Lagoon Nebula.
Both nebulae are a few thousand light-years distant
but at the far right, the dominant celestial beacon is a "local"
source, the
planet Mars.
Just passing through Sagittarius and
strongly overexposed in this picture,
the Red Planet
was a short 4 light-minutes away.
Now headed
for its
closest approach to planet
Earth in recorded history, Mars rises in the east southeast
by midnight shining brightly at about -1.4
magnitude.
