Where, how astronomers could find alien life

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 moon of Jupiter 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 Saturn 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.
