The Area Of Milky Way


The Area Of Milky Way

The diameter of the Milky Way is around 1,00,000 light years.It circles the whole sky which one can see wherever one is on the Earth. In the North, the constellations 
( groups of stars) it goes through include
 Auriga, Cassiopeia and Cygnus. Dark patches in the Milky Way are actually clouds of dust cutting out the light from the stars. The most famous one, 'the Coalsack', is in the Southern Cross.
