Space: Are We Alone?
People always wonder if they could someday visit alien planets. They could start a search of life. Are we really alone, no were not, we share this planet with 10 million other species. On Mars it’s too cold and Jupiter is just a giant boll of gas and so are Saturn and Neptune. Beyond our solar system are other suns and usually where there is a sun are planets. The last 45 years a scientist program wanted to find out if we’re really alone, this project was called SETI. They used radio to listen what’s going on in space.
