Ram Pressure Stripping and Blue Shift in Messier 86
Messier 86, a member of the Virgo Cluster, is currently experiencing a fascinating phenomenon known as ram pressure stripping. This occurs when a galaxy moves at a high velocity through the cluster, causing the gas within the galaxy to be stripped away due to the intense pressure exerted by the surrounding intracluster medium.
The result of ram pressure stripping in Messier 86 is the formation of a spectacular tail trailing behind the galaxy. This tail consists of hot gas that has been forcefully expelled from the galactic disk. X-ray observations have provided valuable insights into this process, capturing the presence of this gas trail.
One notable observation in Messier 86 is the blue shift displayed by the galactic spectrum. This blue shift indicates that Messier 86 is moving towards the center of the Virgo Cluster from the opposite side. It is unusual for a member galaxy to have an approaching velocity, and this can be attributed to the strong gravitational field at the core of the cluster.

Messier 86, a prominent member of the Virgo Cluster, is known for its remarkable collection of globular clusters. These clusters are densely packed groups of stars that orbit around the galaxy’s center. Although Messier 86 hosts a substantial number of globular clusters, their population is not as extensive as those found in its neighboring giant galaxy, Messier 87. Approximated at around 3,800, the globular clusters in Messier 86 contribute to its stellar dynamism and visual allure.
Alongside its globular clusters, Messier 86 also exhibits stellar streams within its halo. These stellar streams are believed to be remnants of dwarf galaxies that were disrupted and subsequently absorbed by Messier 86. These streams are composed of stars that once belonged to these dwarf galaxies, stretching across the galaxy’s outer regions. The presence of these stellar streams signifies the intricate history of galactic interactions and mergers within the Virgo Cluster.
