From the beginnings of telescopic observations of Mars, people have speculated about whether life could have started on the planet and what that life might be like. In this respect the discovery of even a single example of extraterrestrial life, no matter how elementary in form or substance, would represent a fundamental revolution in science. Life on Earth, structurally based on carbonhydrogennitrogenand other elements, uses water as its interaction medium.
How to Write a Summary of an Article? Think about it, there are trillions of other stars in existence in our universe, and most of those stars have satellites, and those satellites have satellites. There are literally hundreds of trillions, if not more, planets or planet-sized satellites orbiting stars.
If it happened to our planet, out of hundreds of trillions of them out there, it can happen to another, and another. Belief in extraterrestrial life dates back quite far, even back to ancient society.
Arguing affirmative were the Epicureans, so called after Epicurus B. But where could life be sustained?
Fix Research and discoveries by Dr. Organisms frozen in soil continue to be bombarded by radiation from elements within the soil itself.
And at any temperature above absolute zero, all molecules vibrate a little. For organisms to remain viable for long periods of time, they must somehow maintain a minimal level of molecular repair.
Mars, the fourth and last Solar terran planet, could hold, or have held, life on its surface. Recent study of an Possible extra terrestrial life meteorite strengthens this theory.
The carbonate minerals may have been deposited when liquid water seeped into the cracks. The impact of an asteroid or comet on Mars 16 million years ago ejected the rock from Mars into interplanetary space. About thirteen thousand years ago the rock fell into the Antarctic ice fields as a meteorite.
The most dramatic evidence, however, is tiny structures in the carbonate globules that resemble microscopic fossils of ancient terrestrial bacteria. Fix Life may be closer than we think, but it also may have died out eons ago when the liquid water on the surface of Mars seemingly refused to stay in liquid form any longer.
While being much cooler than our own planet, again, organisms that live there could adapt to the temperature, as well as atmospheric pressure it sustains; a pressure of 1. These hydrocarbon rich elements are the building blocks for amino acids necessary for the formation of life.
The last is an especially important molecule; it is a building block of amino acids. Its surface is covered completely by a shell of ice, cracked and scarred by tidal forces deep beneath.
Under its frozen crust, Europa may harbor the key ingredients required to create a habitable environment. One great physicist, Stephen Hawking, believes the possibility of life outside of our planet is too great to ignore. You could be infected with a disease with which you have no resistance.
This theory is to be respected, because many planets and subterran objects may fall in every planetary guideline to support life, just not in the way we see it in ourselves. Life must exist elsewhere, whether it be out neighbor, next door or down the block, or whether it be outside of our closely knit family of planets, moons, asteroids, etc.
It could host similar structure to our own, or be composed differently, and therefore could survive completely different conditions from our own.
|Extraterrestrial Life Possible on Mars – Guardian Liberty Voice||The implications are extraordinary and point to the possibility of a civilization far more advanced than our own.|
|Extraterrestrial life - Wikipedia||There were lakes, streams and networks of underground water of drinking quality, and it is possible that these existed for millions of years.|
|Is Extraterrestrial Life Possible? - UFO International Project||The milky way alone has somewhere between and billion stars. It's likely that many of these stars have planets, but it's what the ratio of planets to stars is; to be on the safe side, lets say there's one planet for every hundred stars.|
Simply put, it may be considered to be foolish to completely ignore the possibilities of any terran planet to sustain life, because life is almost certainly out there somewhere, and it may be the in last place we think to look.
Works Cited Crowe, Micheal J. The Extraterrestrial Life Debate Journey to the Cosmic Frontier. Harvey, Samantha and Autumn Burdick. The Daily Galaxy, Intelligent life, as we know it, is probably extremely rare in the universe, but it is also quite possible, given the multitude of planets and probability for suitable conditions.
So, in response to the topic, yes. Extra-terrestrial life is possible. Sep 02, · Hawking founded the Breakthrough Listen project to investigate — and identify — signs of intelligent life in the universe. Russian internet billionaire Yuri Milner is also behind the initiative. The 15 signals came from FRB Once thought of as a lush alien world teeming with life and later dismissed as an arid, desolate orb, the Red Planet’s salty, liquid water just might aid in the search for extraterrestrial life.
It depends on what you mean by life. If you mean intelligent life that traveled through space to meet us, there are three broad possibilities. (1) They will look roughly like us, due to the theory of convergent evolution. Under this theory, evolution drives creatures toward similar traits to handle.
An Exploration of Possible Extraterrestrial Life in the Universe, Perhaps Our Own System Other life in the universe just makes sense. Think about it, there are trillions of other stars in existence in our universe, and most of those stars have satellites, and those satellites have satellites.
The first-ever observations of merging binary stars stunned the astronomy community last year, but not quite as much as the first-ever signal from extraterrestrial life might someday stun the world.
