Can life be sustained on Mars? This has been a very intriguing issue until scientists began to explore and make the necessary steps to find out if this is as true as it was claimed to be.

Before, the questions and myths regarding this matter were endless; but today, the queries that we may have asked ourselves decades before and the myths that we almost began to believe are almost reaching a conclusion. But, right now, try asking yourself again: Is it possible that Mars can sustain life?

It was once thought that Mars was a very hostile planet because of its cold temperature. But in 2004, methane gas-a biological substance which can be a source of life-was discovered. The possibility that methane gas can support life lies in the fact that its molecule can be broken down only by bacteria. This hints therefore the probability that bacteria exists on Mars.

Scientists linked the issue with the meteorite found in Antarctica in 1984. The meteorite supposedly carried magnet-producing bacteria known as ALH84001 and was thought to be of Martian origin. There were worries, however, that the material was based from Earth and not from Mars. But the fact that magnetites do not require much oxygen to survive creates the possibility that it may have come from Mars.

Aside from that, the possibility that existence of tectonic plates and active volcanoes may exist in Mars may also contribute to the fact that life can sustained there. That is because the heat produced by the volcano will melt the icy surface found in there, creating an environment that is fit for life to thrive. This is also one of the key main things that scientists are hoping for.

Though this may just remain a possibility, this may not remain in the realms of science fiction anymore. Sooner or later, time will tell what the scientists will find in there. And once that happens that is when we will start to believe that science fiction will be much closer to reality than we know it.
