When and where are we most likely to find extraterrestrial life? world's two biggest telescopes and will give $1m to anyone who can find aliens first. In , Esa decided to go it alone and announced the Jupiter Ice Moon. For the first time in human history, we have the means to answer the question. The Fermi paradox, or Fermi's paradox, named after physicist Enrico Fermi, is the apparent . The second form of the question is "Why do we see no signs of intelligence elsewhere in the universe? .. why SETI has not found any signals from alien civilizations, but I find it more plausible Paul Speigel (October 18, ).
Nicolaus Copernicus made perhaps the first powerful case for it inwhen his seminal work "On the Revolutions of the Celestial Spheres" showed that Earth revolves around the sun, rather than the other way around. And recent alien planet discoveries continue to remind us of this fact.The Race To Find Alien Life Panel Discussion - SETICon 2012
Scientists have already detected more than planets beyond our solar system, and several thousand more await confirmation by follow-up observations. Some of these exoplanets are small and rocky, like Earth, and some orbit in their stars' habitable zone, that just-right range of distances where liquid water could exist on the planet.

We also have a few historical test runs that shed light on how people might react if we ever do discover E. In the early 20th century, for example, many people regarded the so-called "canals" of Mars as strong evidence of an intelligent civilization on the Red Planet. And in the mids, scientists announced the discovery of possible microfossils in the Martian meteorite known as ALH In neither case did the walls of churches, mosques and temples start to crumble.
The debate over ALH continues today, but most Mars scientists remain unconvinced that it contains strong indications of life.

This microscopic shape was discovered within Martian meteorite ALH, with the debate still on over whether it is a fossil of a simple martian organisms that lived 3. Thomas-Keprta Lockheed-MartinR. Further, the news that we're not alone in the universe likely wouldn't come as a huge shock, because large numbers of people in the United States and abroad already believe that E.
At least, the last poll I saw in the United States was that most Americans believe that there's extraterrestrial life.
Charles Cockell In uncovering the secrets of life's survival on the Earth, astrobiology has some found remarkably prosaic applications. The powder that works in your washing machine at high temperature functions because it contains proteins extracted from microbes that grow in volcanic hot springs. They were first found by scientists who would today call themselves astrobiologists seeking to know how life adapts to such primitive, searing surroundings.
How the search for aliens can help sustain life on Earth
As astrobiologists dig and scrape in amongst the microbial inhabitants of Earth's most hostile environments to understand the possibility of life elsewhere, they learn things that have economic uses. The link between the search for extraterrestrial life and our Earth-based problems is not surprising, because fundamentally it is all the same thing -- understanding how life, whether us or microbes, can be sustained in the cosmos.
A hypothetical microbe on Mars might need to adapt to live in a high temperature stream. A human on Earth needs to find a way to clean its washing at high temperature. Both are trying to make a living on a planetary surface and both are trying to do this as efficiently as possible without wrecking their living conditions.
Both might find that they can share a common way of accomplishing these things. Super telescope to search for secrets of the universe It isn't uncommon to find environmentalists who are in awed disbelief that we can be spending billions searching for life on Mars and space explorers who feel that a focus on environmentalism narrows the reach and vision of our civilization. Both groups of people are separately emboldened by their vision.
Environmentalists understand the great challenges that lie ahead in dealing with a population of seven billion apes inhabiting a piece of rock a mere 12, kilometers in diameter; space explorers understand that if they achieve their vision, and establish a permanent human presence beyond the Earth, they will not only open new opportunities for knowledge and resources, but they will also enhance our civilization's long term chances of survival.
