The Large Cloud of Magellan
Credit:
Magellan and his crew had plenty of time to study the southern sky
during their famous voyage around the world. As a result, two fuzzy
cloud like objects, nestled among the southern constellations of Doradus
and Tucana are now
known as the Clouds of Magellan. The Magellanic Clouds are small irregular
galaxies, satellites of our
larger Milky Way spiral galaxy.
The Large Magellanic Cloud
(LMC) pictured above is the closest galaxy to our own Milky Way,
at a distance of about 180,000 light years.
The Magellanic Clouds are joined to the Milky Way by a
stream of cold hydrogen gas whose origin is still controversial.
An unusual effect called
gravitational lensing has recently
been detected in a few LMC stars, and there is hope this could
tell us important information about the
true composition of our universe.
