Enceladus

Enceladus the 6th largest moon of a Saturn has been found to be a possible victim of cosmic hit and run. While running through the data which was collected by Cassini mission of NASA, the astronomers from Cornell University, The university of Texas and NASA during the flybys of Enceladus found that the moon axis has been reoriented.

Investigating and examining through the various geographical features of moon the group was able to show how the Saturn’s 6th largest moon appeared to be tipped away from the original axis by 55 degrees. When asked about this matter the lead author Radwan Tajeddine replied about his observations. He said to have found a chain of lowland areas, or basins probably. Where they got a trace of belt across the moon’s surface believed to be a fossil remnants of a previous equator and poles. The pattern directs a spatial variation in the moon which was clearly marked in the Cassini images.

The moon’s current southern region releases water vapour, organic compounds, gases, salts and silica through the vent present at the deep beneath the ocean of the moon’s icy-crust surface. The place where all these features were marked is known the south polar terrain and the astronomers have named these long geological fractures as Tiger Stripes. It ranges about 80 miles long and wide about a little over a mile.

According to Tajeddine an asteroid might have struck the moons South Polar Region when it was near the equator in the past. The various internal processes might have been initiated due to the geological activity in the terrain. So the main reason of this reorientation of the moon might be possible due to the impact which was the main reason behind the formation of this anomalous terrain.

The reorientation of the axis of this 6th largest moon of the Saturn has questioned the impact of the possible asteroid attack. The topographic and geological features of the Enceladus can be understood through the geophysical processes, but to the surprise, the moon’s north pole, as well as south poles, are found to be different from each other. The southern part is active and geologically of younger rather than north which is entirely covered in craters and appeared to be much older than the south. This new observation has been found out to be one of the most exciting features of the Saturn’s reorientation.
