Life in the Universe

Astronomy 141, Life in the Universe, is an introduction to Astrobiology. The topics covered in this course lie at the interfaces between astronomy, chemistry, biology, geology, and the earth and planetary sciences. We will learn about scientists' ongoing quest for answers to some of the most fundamental human questions: How did life originate on Earth? Is there life on other worlds? Are we alone in the universe? What is the long-term future of life in the universe?

Life in the Universe

The Life in the Universe curriculum is a unique set of resources, for elementary and middle school teachers, designed to bring the excitement of searching for life beyond Earth into the classroom. The SETI Institute, with funding from NSF and NASA, developed these award winning classroom materials with a team of educators, curriculum developers, and scientists. The Life in the Universe curriculum explores many facets of how scientists are trying to answer the questions: Where did life come from? What is its future? Are we alone?
In the Life in the Universe curriculum, students explore conditions that support life on Earth, and the possible existence of life elsewhere. The curriculum draws upon the experience of SETI scientists, whose research encompasses the full spectrum of Astrobiology: astronomy, life sciences, Earth sciences, chemistry, physics, mathematics, engineering, and many other disciplines. The hands-on science activities were tested nationally in a variety of schools representing a broad range of students. Organized around story lines, these activities pose challenges that require students to investigate what is known about life on Earth.

Russians drill into Lake Vostok, begin search for life under Antartica’s surface:

Russian researchers reported Wednesday that they had reached Lake Vostok, which is located in the central part of Atartica, approximately 800 miles East of the South Pole. This ancient freshwater lake was buried under 12,365 feet of ice, and is believed to have been cut off from the atmosphere for at least 14 million years - a pristine body of water untouched by light or wind. They want to know what type of microbial life — bacteria too small to see — might exist there.

If scientists find these tiny germs in Lake Vostok, it bolsters already strong hope that elsewhere in our solar system, life also might exist where once it didn’t seem possible.

Two Earth-sized planets found orbiting another star

The planets are the smallest ever confirmed orbiting a sun-like star, and their discovery, reported Tuesday, is an important milestone for NASA’s Kepler mission.

http://articles.latimes.com/2011/dec/20/science/la-sci-planets-20111221

Kepler-20e and Kepler-20f, as the two rocky planets are called, are interspersed with three larger, gaseous planets, believed to be similar to our own Neptune, in an alternating pattern that has astronomers somewhat perplexed. All five planets orbit their sun at a closer distance than Mercury orbits ours.

The Odds of Intelligent Life in the Universe

A paper published in the journal Astrobiology, by Andrew Watson a scientist from the University of East Anglia, suggests the odds of finding new life on other Earth-like planets are low, given the time it has taken for beings such as humans to evolve combined with the remaining life span of Earth.

I think that we are not alone in the universe, too many events have made me understand this, the mysteries that surround the Earth and ‘universe are dozens and among these there is evidence of UFO sightings in the past and especially in this time, the universe is infinite and it is impossible that we are the only form of life present.

I think that inquiring into the possibility of life on other planets is a good and interesting thing, and I’d like to do it. I believe that life could exist in the Universe far from the Earth, and I don’t exclude the existence of life forms similar to the humans’ one (for me, everything is possible until the Science demonstrates I’m wrong). In my opinion the discovery of life in other planets would be a magnificent achievement of the humanity,so I’d like to study about astronomy and life when I’ll be older

Some scientists say it is impossible that there is life on other planets,others say that there may be a new form of life.I think it’s possible because if there is life on Earth can there be life on other planets …

    Do you know scientists that said that life on other planets is impossible? Can you tell me how said that?

    Sorry, who said that, not how…

Jupiter’s moon points to alien life in outer space—A body of water as big as North America’s Great Lakes could lie beneath Europa, a shining enigmatic moon of Jupiter.

http://www.news.com.au/technology/sci-tech/jupiters-moon-gives-hope-of-alien-life/story-fn5fsgyc-1226198468906

The theory is exciting because water is one of the key ingredients for life. Europa is the second-closest satellite of Jupiter, the biggest planet of the solar system.

Pictures of it sent back by the Galileo spacecraft during its 1995-2003 exploration point to a tortured surface of cracks and jumbled ice.

I think there are life forms in the universe not yet established, does not mean human people, but small beings or micro-organisms and to exclude the presence of a Martian (hoping not to be wrong)! In this regard, I would suggest you start of scientific research as soon as possible to resolve finally this doubt !!!
