    The search for life outside the Earth may have moved to a new and exciting levelA team of astronomers(天文学家)said they have found a new planet that has many important parts similar to those of the Earth

    The planet, which travels around a red dwarf star(红矮星)called Gliese 581, has the right size and temperatureMost importantly, the planet lies in the suitable living area of the star, which makes the planet not too hot or too cold

    Scientists say the new world, Gliese 581C is five times larger than the EarthIt may have water since it is in the right place for the red dwarf to survive in space

    Swiss scientist Michel Mayor said it is an important step on the way to find possible life in the space and there are still lots of questions

    For more than ten years, astronomers and scientists have been keeping their eyes on the space in search for another Earth, another world that can support life or already has it

    According to records, the first discovery of extra solar(太阳系)planet going around a normal star was made in 1995Since then, the number of newly discovered worlds has increased to about 200But they are just dead with lifeless bodies
