Content: Mars, for example, is found within the habitable zone of our system, and we have yet to find the first Martians. Also, being in the habitable zone doesn’t mean they actually have water, but they could. These potentially habitable planets need to meet other requirements to be able to host some sort of life, like having an atmosphere, being a rocky planet (and not one made up of gas) and having the right mix of chemical compounds needed by living organisms.

So Is there life on other planets? This question has been in the mind of people for aeons, and maybe now we are finally close to getting an answer. Several celestial bodies, either planets or their moons, have been identified as potential candidates to host life. Some are planets around the same size of Earth, orbiting a star much like our own Sun. Others are called super-Earth planets and are as large as 45 times the size of Earth. In the search for life on other planets, the most famous candidate, arguably, is Mars, which made some big news recently when it was confirmed it hosts a vast amount of water just beneath its surface. The finding, according to experts, means that Mars could one day allow for the establishment of a human colony and perhaps even allow some other life forms to exist.
