Scientists are becoming more convinced that there is alien life, and they say there are several possible scenarios that could lead to such a discovery:
• Mars. The red planet has water underground and used to have even more water, which is key to life. Scientists think there's a good chance microbes could be living underground, even though robot rovers have not found such evidence.
• Europa. This [COLOR=#366388 !important][COLOR=#366388 !important]moon [COLOR=#366388 !important]of [/COLOR][COLOR=#366388 !important]Jupiter[/COLOR][/COLOR][/COLOR] has radiation on the surface that would kill life. But under a frozen ocean there is a chance that some type of microbes live in the liquid part below, perhaps near hydrothermal vents.
• Enceladus (pronounced en-SELL'-ah-dus). This tiny moon of [COLOR=#366388 !important][COLOR=#366388 !important]Saturn[/COLOR][/COLOR] has supersonic plumes of gas and dust shooting from its surface that indicate it could have all-important liquid water.
• Titan. Saturn's largest moon has liquid oceans, but they are likely methane.
• On a planet outside our solar system. It is possible that astronomers using telescopes could detect an atmosphere on such a planet that could only be explained by photosynthesis or other biological processes — for example, if there was a combination of oxygen and other reacting gases in certain proportions.
• On Earth. Scientists could find life that came aboard a meteorite or comet. They also could find life — deep in the sea or beneath Antarctica's ice — that is so unusual it probably came from space.
• In radio signals. Scientists are scanning for alien transmissions from space.
