Life beyond Earth does exist. The life that exists beyond Earth is only simple microbial life. In order for complex life to exist many specific events would have had to happen which is highly unlikely. Spacecrafts have found regions of other planets that appear to be able to sustain simple life. Simple life forms have been found on Earth in extreme conditions never thought possible. On someplace other than Earth simple life forms do exist. If complex life were to occur on places other than

of Mars and Jupiter. They have orbital periods of three to six years. Some asteroids have very eccentric orbits and travel very close to the sun‚ and a few larger ones regularly pass close to Earth and the moon. Many of the most recent impact craters on the moon and Earth were probably caused by collisions with asteroids. Many asteroids have irregular shapes. Because of this‚ planetary geologists first speculated that they might be fragments of a broken planet that once orbited between Mars and

Earth‚ the planet that is said to have the most resources to sustain life. A planet that allows us as humans to be born in and continue to live in as we age because of its amazing resources. It isn’t blazing in flames like the Sun‚ or composed of rock and ice like Pluto‚ Earth has water‚ trees‚ and rotates around the sun for heat. It is almost as if Earth were tailored when created to fit human need’s‚ we drink water and breathe its oxygen to survive‚ we use its plants for various reasons‚ from eating

Origin of Earth and Evoluation of the Environment MODULE - 1 Environment through Ages 1 ORIGIN OF EARTH AND EVOLUTION OF THE ENVIRONMENT We live on a beautiful planet called earth‚ along with a wide variety of plants‚ animals and other organisms. Our earth‚ however‚ is part of a vast universe. The universe is about 15 to 20 billion years old. The age of the earth is approximately 4 to 5 billion years‚ while human beings evolved only around 2 million years ago. In this lesson‚ you shall learn

The NASA team said that the New Horizons can store as much as data and information about Pluto planet and its moon. From this mission the flyby process will last from the month September‚ 2018 through the January 2019. After that it will probably take 20 months to beam the flyby data to the home. About half of the flyby data and information has come

[2] The planets The research expands to include the terrestrial planets‚ and their satellites. This involves the physics of the interior‚ the geology of the planet or satellite surface‚ the surface morphology‚ and studying their tectonics‚ mineralogy and dating. Observing the outer planets and their satellites includes studying formation and evolution. This method of observation and study involves remote sensing at all wavelengths and in situ measurements. Planet formation and planet evolution
