M98 - Spiral Galaxy in Coma Berenices
is one of the faintest of the Messier objects. It is a member of the
Virgo Cluster. It was discovered by Pierre Mechain in 1781 and cataloged
by Charles Messier the next month. This spiral galaxy shows some distortion
in its arms. This is beleived to have been caused by a close encounter
it had with another galaxy - NGC4254. Another peculiarlity about this
object is that is exhibits a blue shift. That is, it is approaching
us rather than moving away, as most galaxies are.
