March 20, Does life exist on other planets other than Earth? Does life exist on other planets besides here on Earth?
Solar System Life on other planets, Is there another titan planet out there that harbors life? Scientist have found two such planets in a neighboring but distant Solar System.
The fascination of intelligent life other than us has led to many studies and theories. The implications of proving life exists on other planets and communicating with them could have an enormous impact to our society.
The following discusses the possibilities of life on other planets by studying what sustains life on planet Earth, possible life within our Solar System, the discovery and study of other life bearing planets, examines what criteria may sustain life in other stars systems, and current programs studying extraterrestrial life Koch and Borucki, Recent Essay for life on other planets advancements have confirmed the existence of relatively large planets around other stars.
Earth-like planets orbiting other stars have yet to be discovered, but most astronomers believe one will be found. In order for a star to maintain a potentially life-giving planet within its orbit certain criteria would have to be established and maintained.
Stars have been classified by The Harvard one-dimensional temperature classification scheme based on hydrogen Ballmer line strengths was developed in Harvard College Observatory in by Annie Jump Cannon and Edward C. Pickering Koch and Borucki, This classification is ordered from hottest to coldest, comparing mass, radius and luminosity to our Sun.
These star types span the range of star temperatures.
Spectral type is determined strictly by temperature: O type stars are the hottest stars and M type stars are the coolest. Any other type planet would be too cold to support life. Our Sun is presently a G-2 class Star, which because of size and photospheric temperature is best suited for sustaining life as we humans understand it.
Different stars within the classification of F and G vary from white or yellow-white stars with medium to weak hydrogen lines have been researched by astronomers as potentially being conducive to the development of life.
The Habitable Zone is a region surrounding a star throughout which the surface temperatures of a planet would be ideal for life formation and be life sustaining Kasting, Whitmire, Reynolds With this technology, humankind has made advancements that enable more accurate research and validation to the science of astronomy.
Scientists worldwide are involved in research of location and identification of new planets and unexplained occurrences within the universe, along with exploration of life on other planets.
Space travel performed by organizations such as NASA are assisting in dispelling many myths about our current solar system and the existence of life on any of these other planets, while organizations such as Meta Research Inc.
To see if worlds like Titan could host oceans when not orbiting Saturn, McKay and planetary scientist Ashley Gilliam calculated what a Titan-like world might be like while orbiting around a relatively dim M4 red dwarf star.
The seas of Titan are made of liquid methane, often leading to speculation as to whether or not they could host life, much like how life on Earth depends on water.
Such aliens would consume organic compounds just as Earth life does, but inhale hydrogen gas in place of oxygen and exhale methane instead of carbon dioxide Choi, C. The researchers also calculated what Titan could be like orbiting a slightly hotter M3 red dwarf star, such as Gliese A number of planets have already been detected near it now.
The light from a red dwarf star has more infrared than our sun does. If Titan was placed at a distance from these red dwarfs so that it received the same average amount of light as it received from the Sun, the scientists estimated this extra infrared could warm its surface by about another 10 degrees C.
Due to flares, red dwarf stars can generate more particle radiation and specific kinds of ultraviolet rays than our sun does. Nevertheless, liquid seas would be possible, the investigators found — such oceans would exist if Titan was 8.
If Titan was a rogue planet with no star to call home, the researchers wondered if it could still be covered in seas due to geothermal heat. The researchers calculate Titan would need to release about 20 times more geothermal heat than Earth does to keep its current surface temperature, which is unrealistic for a world its size.
However, if its atmosphere was 20 times thicker than current levels, it could retain enough heat to still have surface oceans. In order for a starless planet to have liquid methane seas on its surface, a more realistic scenario might be for it to be both larger and warmer than Titan and have a thicker atmosphere, he suggested Choi, C.
Organizations such as the Search for Extraterrestrial Intelligence SETI continue to search for other life forms that exist throughout the universe. Ongoing studies and research for microbial and non-intelligent forms of life Choi, C. Light and radio waves travel at a slow rate throughout the never-ending universe, making contact with possible intelligent life forms from other planets almost impossible.
Over two thousand years ago Titus Lucretius Carus was certain there was life elsewhere in the Solar System and he was not the only person to assume this. Many scientists and philosophers around this time, and even present day scientists and philosophers, would have agreed with his statement.
Roughly one and a half thousand years later, Galileo found spots on the Sun plus he distinguished the movement of the mountains and seas of the moon through his telescope; could these be indicators for life elsewhere?Is there life on other planet?The life in the Earth was created long before, even before the existence of human being.
For many years, scientists have been researching if there is any life on other planets, or the Earth is only the planet that consist benjaminpohle.com is no sufficient evidence to prove that life on other planet exists, however, scientists have found some evidence of life on other.
One of the biggest arguable questions of all time is whether or not there is life other than that on the planet Earth.
