Clouds of the Large Magellanic Cloud - UNIVERSE
The Large
Magellanic Cloud (LMC) is an alluring sight in southern skies. But this deep and
detailed telescopic view, over 10 months in the making, goes beyond what
is visible to most circumnavigators of
planet Earth. Spanning over 5 degrees or 10 full moons, the 4×4 panel mosaic
was constructed from 3900 frames with a total of 1,060 hours of exposure time
in both broadband and narrowband filters. The narrowband filters are designed
to transmit only light emitted by sulfur, hydrogen, and oxygen atoms. Ionized
by energetic starlight, the atoms emit their characteristic light as electrons
are recaptured and the atoms transition to a lower energy state. As a result,
in this image the LMC seems covered with its own clouds of ionized gassurrounding
its massive,
young stars. Sculpted by the strong stellar winds and ultraviolet
radiation, the glowing clouds, dominated by emission from hydrogen, are known
as H II (ionized
hydrogen) regions. Itself composed of many overlapping H II regions, the Tarantula Nebula is
the large star forming region at the left. The largest satellite of our Milky
Way Galaxy, the LMC is about 15,000 light-years across and lies a mere 160,000
light-years away toward the constellation Dorado.
