Life on Mars?
David Bowie sang about it, but scientists have found that it could actually happen in the near future.
Scientists at St. Andrews University who have been studying the solar system have found evidence that they could be capable of supporting life. Exoplanets; worlds which orbit other stars apparently have electrified gas clouds in their atmosphere containing electrons and ions, which would provide the perfect atmosphere for life to grow. The minerals found in the exoplanets' atmospheres are similar to those used to make fluorescent lights and plasma TVs.
This, dust, when charged, grows molecules from being able to attract other charges to its surface. Of course, Earth is a unique world, but the scientists are convinced they may one day be able to use these molecules to support some form of life.
Exoplanets found so far have been huge and rocky, with heavy gravity or like 'versions of Neptune', which are wetter and made of gas. Neither of these would be able to support life, so this is a significant find for the scientific community. They still have not found a twin planet to match earth, but scientists are hopeful that this find will lead to a breakthrough for life on other planets.
