Is There Life On Mars?

Earth is the only place that we know for certain supports life. Many claims have been made by observers who thought they saw evidence of life on Mars, but we now know they were tricked by the very difficult measurements. From Earth, even with our most powerful telescopes, we just cannot see enough detail on Mars to answer this question. We need a close-up look at the planet.
 
1.The finding of a 'cell-like' structure, which investigators now know once held water, came about as a result of collaboration between scientists in the UK and Greece. Their findings are published in the latest edition of the journal Astrobiology.
 
2. While investigating the Martian meteorite (A Martian meteorite is a rock that formed on the planet Mars and was then ejected from Mars by the impact of an asteroid or comet, and finally landed on the Earth. Of over 61,000 meteorites that have been found on Earth, 132 were identified as Martian as of 3 March 2014 ) found an unusual feature embedded deep within the rock. In many ways it resembled a fossilized biological cell from Earth but it was intriguing because it was undoubtedly from Mars. These findings are significant because they add to increasing evidence that beneath the surface, Mars does provide all the conditions for life to have formed and evolved. It also adds to a body of evidence suggesting that large asteroids hit Mars in the past and produce long-lasting hydrothermal fields that could sustain life on Mars, even in later epochs, if life ever emerged there.
3. Researchers at the University of Michigan have found that despite Mar’s sub-zero temperatures, small amounts of liquid water are able to form on the planet's surface at the right temperature and with the presence of salt - furthering the idea that the planet can support life.
 
4. Earth-like soils on Mars- The ancient soils do not prove that Mars once contained life, but they do add to growing evidence that an early wetter and warmer Mars was more habitable than the planet has been in the past 3 billion years.
 
5. Most scientists agree that the results do not reveal any signs of life. The spacecraft had cameras that returned thousands of images of the surface, showing the changing seasons and details of the rocks and dirt near the stationary landers.
