Life in Outer Space The answer to the above question is I don't know. This essay is not an essay of answers because nobody knows the answer. What I want to do is speculate. My speculation will be controlled and based on the knowledge we have at present.
So, if we were to receive any kind of signal from outer space, it would be from the distant past, and there would be no guarantee that the life forms are still alive. Have we reached a setback in our quest to find intelligent life in outer space? Yes. Does this mean we are going to stop searching? Definitely not.
Space a waste?!!? Throughout the years there has been an increase in people against the idea of space exploration they believe it is foolhardy and a waste of money. Though space travel in not wasting money or blindly throwing resources away. Space exploration is an investment as we progress forward.
It is believed that if a planet looks like Earth and has liquid water and oxygen, then this would present strong evidence for its having life. If there is other life out there, what are the chances of finding it in our lifetime, or even our children's lifetime. Conditions have to be just perfect to develop life.
Living in space is not the same as living on Earth. In space, astronauts' bodies change. On Earth, our lower body and legs carry our weight. This helps keep our bones and muscles strong.
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.

The science of extraterrestrial life in all its forms is known as astrobiology. Since the mid-20th century, active ongoing research has taken place to look for signs of extraterrestrial life. This encompasses a search for current and historic extraterrestrial life, and a narrower search for extraterrestrial intelligent life.
The 12-hour working day on the International Space Station begins with a wake-up call. After a quick rub down with a soapy cloth, the crew have breakfast and run through the jobs for the day with mission control. Space stations are like large, complicated houses that need constant care and attention.
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.
