Astronomy may be within a decade or so of helping to answer one of the most intriguing questions in science: Does life exist elsewhere in the universe? Besides searching for life in our solar system and attempting to detect signals from other civilizations, astronomers are looking for planets that seem conducive to life and trying to detect signs of life in the light we receive from them.
The discovery of many giant planets orbiting other stars shows us that planets -- at least Jupiter-like planets -- probably are common. There is little chance of life on such planets, though. To find life, astronomers are trying to detect small, rocky planets similar to Earth. This lies beyond current abilities, although it may not be far off.
Most of today's planet-finding methods detect the effects of planets on the motion or light of the stars they orbit; they cannot "see" a planet directly. To find the signatures of life, astronomers must take pictures of and analyze the light from the planets themselves. But Earth-like planets around other stars are small and faint, so direct imaging will require large space telescopes that can block the light from the parent star.
No one has come up with a complete definition of "life," but astrobiologists (the scientists who study the possibility of life beyond Earth) are narrowing the search to the type of life that's most familiar to us -- "life as we know it."

THE MOST IMPORTANT SIGN OF LIFE IS THE PRESENCE OF CELL IN THE BODY AS THE CELL IS THE BASIC UNIT OF LIFE.
