Comet West was discovered in photographs by Richard West on August 10, 1975. It reached peak brightness in March 1976. During its peak brightness, observers reported that it was bright enough to study during full daylight. Despite its spectacular appearance, it did't cause much expectation among the popular media. The comet has an estimated orbital period of 558,000 years.
Although most galaxies fall into well defined classifications, there are some that defy all attempts at classification. While some strange and bizarre galaxies are the result of gravitational interactions with other more massive, and sometimes less massive objects, they all have one thing in common; they look more like artists’ impressions than real, tangible collections of billions of stars.
