Is their really life in space?

Question

is their any sign that their was life on any of the planents in space other than earth and if their is on what planet.

Answer 1

Don't know, but it is possible.

Answer 2

Over the next few years, space probes will be visiting alien worlds looking for life. Our first contact with extraterrestrials could be just around the corner.

The main candidates in the Solar System to harbour life are Mars, Europa and Titan.

There may be no little green men living in our Solar System. However, there are plenty of places where more primitive life might be able to survive.

Many astronomers now believe that life has a good chance of evolving wherever the conditions are right. So our Solar System could be teeming with living creatures!

In the 19th century, many astronomers were convinced the Moon was inhabited by intelligent aliens. We now know that this isn't true. The Moon has no atmosphere, so life couldn't survive there.

Even so, the Apollo astronauts were held in quarantine after their trips to the Moon - just in case they had picked up any space bugs.

The Earth is a rocky planet, so it seems sensible to look for life on other rocky planets too. We can ignore Mercury, because it's too close to the Sun, so it's too hot. And Pluto is too cold and far away to support life.

At first glance, Venus is an inhospitable planet. It is cloaked in thick clouds of sulphuric acid. These trap heat and fry the planet to over 500ºC.

Unsurprisingly, Venus was assumed to be a dead world. But now some scientists think life could survive in the clouds.

But the most likely candidate is Mars. Out of all the planets in the Solar System, Mars is most like Earth. And it's also the most likely to contain life.

The giant gassy planets have no solid surface on which life could roam. But could life still fly around in the atmosphere of a gassy planet?

Scientists have wondered whether creatures like jellyfish could survive on Jupiter or Saturn, feeding on organic material in the clouds. However, no evidence has yet been found that such creatures exist.

The moons of Jupiter and Saturn may also be good places to look for life.

Titan, the largest moon of Saturn, could be similar to how the Earth was at the point when life started.

Europa, the sixth moon of Jupiter, is the last candidate in the Solar System that may hold life. Europa is a frozen moon - but it may hide an exciting secret...

Answer 3

The evidence we have is
1. the famous Martian meteorite that apparently had fossil bacteria in it. Most astrobiologists don't actually think they are fossils anymore, but some questions remain about the magnetic material in the "fossils". There is no known process for making that particular form of material except by living things. The meteorite may have been contaminated after it landed on earth, there may be an unknown natural process that can make that material without living cells, or maybe they are really fossils of bacteria from Mars.

2. While on mars, the Viking lander did experiments to detect biological activity. There were three differant tests, and the results were very strange, and may have indicated life. Most experts today believe that the martian soil that was tested had chemical properties we did not expert, and we just detected these non life reactions.

There are lots of theories about life off earth, but these are the only examples of actual evidence I know of, even though they are pretty much considered disproven.

One other piece of evidence is circumstantial, in that equipment left on the moon by astronauts was found to have bacteria on it from earth, but those bacteria had survived months in a vacumn, in extreme tempertures and a radiation hit environment. This is evidence that life is very hardy, and could exist in places we don't expect.

In my personal opinion, if there is life anywhere in the solar system besides earth, it is on Europa, under all that ice.

Answer 4

It would be narrow mindedness not to think that life exist elsewhere in this universe, even if we don't have the proof yet. It would be also egocentric to think we are the only inhabitants of this universe. As it was stupid in the middle age to think the earth was flat. The problem arises when we have to consider that there maybe higher intelligent life forms than us. Nobody wants to believe that of course, so every body is afraid of aliens coming to see us one day.

Answer 5

Check out such websites as enterprisemission.com. The surface of the moon, and Mars are littered with ancient archaeological ruins. Many of them have been photographed by the NASA orbiters, and Apollo astronauts. Of course there is a major cover up going on about all extraterrestrial life. That's why you never hear a word about it.

Answer 6

ofcourse theres a solar system they found like 5 years ago that have a planet pretty much like earth and theres a force that keeps making the universe bigger they think is GOD(probably) so the universe keeps getting bigger obviosly ther have to be other live in the universe plus the ufo and x-files just kiding i belive that theres other life out there.

Answer 7

We are still trying to figure out if there is intelligent life on Earth.

Answer 8

if there was anny sign of life on another planet
nixon would have know about it
all that is out there is dust and gasses

Answer 9

oh son of a *****... where do you think the earth is floating?
