Is there life ( extraterrestrial life or any other form of life) elsewhere in the universe.....a universe consisting of millions of galaxies, nebulas, blackholes, millions and millions of stars, unknown planets and other heavenly bodies millions of light years away from our solar system ?

This we don't know, but we must bear in mind not to rule out the possibility of the existance of some form of life.

The earth, as we already know, is unique in terms of life.

It's size, atmosphere, temperature, distance from the sun, oxygen, and liquid water make earth a planet of life.

The remaining planets are not capable of sustaining life, the reasons being; extreme temperatures, no liquid water, etc.

Mars in fact,is the only planet in our solar system where life may have existed, life meaning microscopic life. By now we all know that photographs show Mars without rivers, oceans or any signs of life. Further it revealed that the surface (at least the parts that it photographed) was covered in craters, indicating a lack of plate tectonics and weathering of any kind for the last 4 billion years.

The probe also found that Mars had no magnetic field that would protect the planet from potentially life-threatening cosmic rays.The probe was also able to calculate the atmospheric pressure on the planet to be between 4 and 7 millibars, meaning that liquid water could not exist on the planet's surface.After Mariner 4, the search for life on Mars changed to a search for bacteria-like living organisms rather than for multicellular organisms, as the environment was clearly too harsh for these.From a scientist point of view, it's highly unlikely to encounter martian life in the form of extraterrestrials.

The "face" on Mars is considered by some as evidence of extraterrestrial life on this planet.This is not true.The face in the Cydonia region is a natural formation, hill or mountain and is not an artificial structure created by extraterrestrials ( aliens). The Face on Mars

Images from NASA probe revealed this mystery human-like figure on Mars or is it part of a rock formation created by natural forces on the landscape of Mars?? The latter is probably the case.

Allthough there is no evidence of liquid water on any of the planets, scientists believe liquid water may exist underneath Europa's ice crust. Europa, as seen by the Galileo spacecraft.This image shows two views of the trailing hemisphere of Jupiter's ice-covered satellite, Europa.

The left image shows the approximate natural color appearance of Europa. The image on the right is a false-color composite version combining violet, green and infrared images to enhance color differences in the predominantly water-ice crust of Europa.

Dark brown areas represent rocky material derived from the interior, implanted by impact, or from a combination of interior and exterior sources. Bright plains in the polar areas (top and bottom) are shown in tones of blue to distinguish possibly coarse-grained ice (dark blue) from fine-grained ice (light blue). Long, dark lines are fractures in the crust, some of which are more than 3,000 kilometers (1,850 miles) long. The bright feature containing a central dark spot in the lower third of the image is a young impact crater some 50 kilometers (31 miles) in diameter. This crater has been provisionally named "Pwyll" for the Celtic god of the underworld.

Europa is about 3,160 kilometers (1,950 miles) in diameter, or about the size of Earth's moon. This image was taken on September 7, 1996, at a range of 677,000 kilometers (417,900 miles) by the solid state imaging television camera onboard the Galileo spacecraft during its second orbit around Jupiter. The image was processed by Deutsche Forschungsanstalt fuer Luftund Raumfahrt e.V., Berlin, Germany.

The universe contains vast numbers of planetary systems similar to our own, increasing the chances of there being extraterrestrial life, astronomers have announced.

With today's most modern and advanced space technology, unmanned space probes and other forms of spacecraft, telescopes,.....it has become possible to explore unknown heavenly bodies far beyond our field of vision.....to unlock the mysteries of the universe.....to gather space data. If there is life out there, scientists will find it.

The purpose of Project Phoenix run by the SETI institute is to detect signals coming from unknown intelligence. SETI focuses on certain stars which appear to be orbited by potentially inhabited planets. This means the project concentrates on about 800 stars with a 200 light-year range.

A radio telescope is used in the process.There are, of course, other radio telescopes in different countries searching space for extraterrestrial signals.

Worthy of note: It has become known in 2004 that after checking the "about 800 stars", it had failed to find any evidence of extraterrestrial signals.
