Sometimes also referred as extraterrestrial biological entities (EBE), extraterrestrial life can be defined as living objects that do not originate on Earth. However, no one has yet sighted these entities and thus there have been many heated up arguments over the existence of such life forms in the past, which have now intensified to a great extent. There are many talks about UFO sightings and alien abduction which still remain unexplained.

However, if any extraterrestrial life does exist, it won’t be in the form of walking and talking scary looking person as shown in movies, but instead it is more likely to occur in the form of cell. There are certain locations in the solar system which might have developed or could host life today.

Recently, an impossible discovery crushed all the barriers that were restricting the possibility of extraterrestrial life in the Solar System. A 3-inch Shrimp was found swimming under 600 feet of ice covering which was 12.5 miles away from open water.
The sixth largest moon of Saturn – Enceladus which boasts of normal temperature and the likely presence of water as well as simple organic molecules is being viewed as the most promising place to find life forms. In the presence of oxygen, nitrogen, hydrogen and carbon, there is every possibility that organic molecules can develop life with the surface covered with 99% water ice.

A mission is also proposed to one of Jupiter’s moon – Europa which is said to contain a liquid water layer underneath its surface. According to scientists, this surface can contain life. There are also reports of volcanic activities, which could provide heat as well as essential chemicals required by living organisms.

There are also some evidences to support the speculation about the existence of microbial life on Mars. Viking Mars lander on Mars expedition reported the emissions of gas, which many scientists view to contain microbes. In 1996, there were reports regarding the structures which resembled nanobacteria were discovered in meteorite, ALH84001. Mars is like Earth, with welcoming temperature and presence of liquid water beneath the surface which could contain some life forms.

Saturn’s largest moon - Titan consists of thick atmosphere, which can support living organisms. There is also presence of methane which might support the existence of living organisms, as it does on Earth.

Lo – Jupiter’s moon consists of complex chemicals as well as volcanic activities, which support the potential of living organisms residing there. Besides this, the magnetic fields, too cold temperature as well as, the presence of molten hot spots are equally deadly which can contradict the existence of extraterrestrial life.

These are just assumptions about the existence of extraterrestrial entities residing in our Solar System, however, there maybe someone actually present there for whom we can be extraterrestrial entities, and there can be someone researching about us there, as we did here.
