Flexi Says: Early observations suggest that many of the extraterrestrial space planets should have habitable environments similar to those that found in our solar system. The Universe contains about a hundred billion galaxies. Several planets, like Kepler-22b, have recently been discovered that are in the habitable zones of a sun-like star. This means that the planet could have liquid water, which is necessary for life on Earth. This planet is larger than Earth, but may have pleasant surface temperatures. Still, the chances that it harbors life are slim, but there are likely many more Earth-like planets in the universe. Scientists are also interested in Jupiter's moon Europa because it may be a place to find extraterrestrial life as there are evidence of an ocean of liquid water underneath. The Saturn's moon Titan is also found interest because its atmosphere is similar to what Earth’s was like before life developed.
