The Question of Intelligent Life in Space Essay - 1135.

The first people to go into space only went up for short trips to see what it was like. Today, astronauts can spend weeks or even months living and working in space. They stay on a large spacecraft called a space station, which orbits, or travels around, Earth.

Is There Life in Space? Students discover how scientists find planets and other astronomical bodies. They compare zones of habitability around different star types, discovering the zone of liquid water possibility around each star type and they explore how scientists use spectroscopy to learn about atmospheres on distant planets.

Editor's note: This essay first appeared in 2003 in NASA's Astrobiology magazine. If the person on next to me on a long airplane flight ever finds out that I am an astrophysicist, nine times out of ten they ask, with wide eyes, about life in the universe. And only later do they ask me about the big bang and black holes.

This is about ten billion years, after which the Sun will swell up and engulf the Earth. An intelligent form of life, might have mastered space travel, and be able to escape to another star. But otherwise, life on Earth would be doomed. There is fossil evidence, that there was some form of life on Earth, about three and a half billion years ago.

MYSTIC MEG, astrologer: Yes, I believe there is life on Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune. I am not sure about Pluto. On the warm side of Mercury the life-forms are circular.

Then there’s life as we don’t know it. While it makes sense to search first for something like ourselves, we don’t know yet if that’s really what we should expect. If alien life is organized around different combinations of molecules than life on Earth, we could pick up a robust signature and never even realize it—a smorgasbord of unrecognizable alien gases almost screaming “Life!”.

Is there life on Mars? Some of our friends at the Lakeview Museum of Arts and Sciences in Peoria, Illinois, wonder whether there is life on Mars. This is an idea that has intrigued people for centuries, and one that I, perhaps like you, have wondered about for most of my own life. Earth is the only place that we know for certain supports life.

Secondly, even if there is no life at all, the surface of Mars should contain some organic molecules. They are ubiquitous in space, and rain down on every planet in the Solar System via meteorites. They are ubiquitous in space, and rain down on every planet in the Solar System via meteorites.

One of the biggest arguable questions of all time is whether or not there is life other than that on the planet Earth. There are facts to prove things for both arguments, and I don't think that anyone can say with 100% certainty that they know the answer.

Space means the whole universe, including the earth, while outer space refers to space other than the earth; outer space begins where the earth’s atmosphere ends and extends in all directions. Like, the air we breathe, space is everywhere and all around us. Most people describe space as the universe and do not distinguish between them.

The potential is there. Around a billion Earth-like planets are estimated to inhabit our galaxy, making the potential for life extremely high. The recent discovery of a super-Earth planet 31 light-years away, and that it could harbor life, suggests that there could be a potentially habitable world outside of our solar system. Even within our.
