A comet has become an object of intense study and debate by area astronomers because of its its dramatic prescence in the night sky. The Comet named "Holmes" appears in the northern sky as a yellowish, fuzzy ball and can be seen with the naked eye even in cities, such as Ottawa, that pollute the sky with light.
The comet follows anunusual orbit between Mars and Jupiter and is a million times brighter than normal. This comet has undergone a dramatic and unexplained increase in size. Astronomers aren't sure what caused this outburst, but oe theory holds that the comet formed a hard and dirty frozen crust that trapped heat inside its shell. When that heat vapourized ice inside the shell, pressure built until being released in dramatic fasion, astronomres speculate.
The comet can be found in the northeast by locating Cassiopeia, the w-shaped constellation that is a prominent feature of the fall sky. Then, track to the lower right into the triangle-shaped constellation of Perseus. Comet Holmes will be the yellow dot in the bottom left of that triangle
