You might have seen aliens in books and movies. They look strange. They are very smart. They travel in spaceships. But are there really aliens in space ？ British scientist Stephen Hawking,68， thinks so. He said that people should not look for aliens because they are dangerous.

On a new British TV program,Hawking said ， " It is quite possible that there are aliens in space. " The universe has many stars. Earth is probably not the only place with life on it,according to Hawking. Hawking said that aliens may live on planets or stars. "We should work out what aliens might look like," he said. "They could be microbes (微生物).They might live in big ships because they have used up all the resources from their home planet. " He thought such aliens might get resources from the Earth and then move on. He said people should not try to find aliens. They may bring disaster (灾难)to the Earth.

In another British TV program ， British scientist Brian Cox said aliens may live on Mars and a moon of Saturn (土星).Early this year,

British scientist Martin Rees said in a meeting, "There might be aliens ， but humans may not be able to understand them."
