The possibility that there is life on Mars has reached a higher level. There is methane that scientists have come across in Mars's atmosphere.

I liked this article because it was very informing and interesting to read. I was surprised to hear that there is even a possibility of life on any other planet than Earth! I learned that methane is a carbon atom with four atoms of hydrogen attached to it. I would like to know if there are any other discoveries that scientists have made about Mars. And I would like to know if methane has been found on any other planets.
