One of the most profound questions of our age may be answered definitively within our lifetime. Is there life beyond Earth?
According to most astronomers, the answer is a definite yes. The universe is so vast, and planets appear to be so abundant that it's almost inconceivable to think that Earth is the only planet that hosts life. However, there still exists no good evidence to demonstrate that such life actually exists.

In science, this is a problem because nothing can be claimed without scientific evidence.
Naturally, astronomers have been working on ways to answer this question. A fast answer to the question should come within 10 to 15 years, according to Frank Marchis, who works for the SETI institute and is a member of a planet-hunting team that expects to use the Gemini Telescope in Chile to image planets around other stars.
