Have you ever seen
another galaxy with your own eyes?
The
featured image shows the
Large Magellanic Cloud (LMC), one of the closest neighbors of our
Milky Way.
If you are anywhere south of
latitude 20° N (but the further south, the better), you can see it
with the unaided eye if you go to a dark sky location, away from big cities and
light polution.
It is a
dwarf irregular galaxy about 163,000 light-years away, and a member of our
Local Group of galaxies.
Despite being small, with a total mass /day/proximately equivalent to
10% - 20% of the mass of the Milky Way, the LMC is very actively
forming stars.
This is likely due in part to the gravitational
push and pull of tides caused by the Milky Way on the LMC.
Some astronomers have predicted that it will
collide with the Milky Way in in about 2 billion years.
