The existence of aliens can be really puzzling, while scientists are trying their best to unravel these secrets, some believe that the moons of Uranus may contain extraterrestrial life, thus they may be closer than people think.
There are 27 known satellites orbiting Uranus, which is three billion miles from Earth. These moons are popularly named after well-known English authors Alexander Pope and William Shakespeare.
Now, the Data from Voyager 2's 1986 journey to Uranus have been reviewed by NASA in this regard.
The scientists believe that the ice beneath the four moons - Ariel, Umbriel, Titania and Oberon, may conceal vast seas that are several miles deep. They could thus be brimming with extraterrestrial life.
New research suggests that Uranus' five big moons are crucial targets for upcoming spacecraft missions. We simulate the internal development of these moons, the physical structures that exist now, and the geochemical and geophysical signs that spacecraft may potentially assess in order to inspire and inform the exploration of these moons.
According to Julie Castillo-Rogez, lead author from NASA's Jet Propulsion Laboratory, with regard to tiny entities, such as dwarf planets and moons, researchers have already discovered evidence of seas in a number of unexpected locations.
Nevertheless, if the moons did retain liquid until the present, it is most likely to have taken the form of residual seas that were less than 50 km thick in Titania and Oberon, and less than 30 km thick in Ariel and Umbriel. It is also said that if the retention of liquid is highly dependent on both the material characteristics and, maybe, as-yet-unknown dynamical conditions.
A team from the University of California investigated last month whether intelligent alien life would have been able to react to signals transmitted from Earth into deep space.
A response might come as soon as 2029, according to experts who examined the signals to see whether they could have reached their intended destination.
