However, within a year, Congress terminated funding. The SETI Institute then sought private funding to continue the hunt for advanced life in the universe. Donations from the enthusiastic public have helped continue the hunt for signals from other worlds.
According to its website, the Institute has over active projects, spanning astronomy and planetary sciences, chemical evolution, the origin of life and climate change. The program carefully examined regions around a thousand nearby sun-like stars with the world's largest antennae.
In a joint project with the University of California, Berkeley, the Institute built 42 individual telescopes that function as a single massive instrument. According to the SETI Institute, the array should allow scientists to examine as many as 1 million nearby stars in the next two decades. Extraterrestrial life can be roughly grouped into two categories.
The first is the broad classification of life itself, a process that includes microbial and other simple forms. Without civilization and technology, life cannot produce the advanced signals that travel across the galaxy. However, many scientists continue to investigate atmospheres and other characteristics of worlds both in and out of the solar system as part of the search for life beyond our planet. The search for extraterrestrial intelligence looks beyond this broad category in an effort to find advanced civilizations.
Most SETI searches focus on the hunt for radio or optical signals that can signify highly evolved alien life. Because life on Earth arose within million years after the planet was habitable, many scientists think that life should evolve on planets with the right characteristics. With billions of stars in the galaxy, each thought to host at least one planet, there are numerous opportunities for life to evolve.
I doubt that any of us around at the beginning would have predicted that, twenty-five years later, the SETI Institute would have administered more than one quarter of a billion dollars in funded research, employed more than different individuals over the years, and would currently host more than active projects with employees, including 55 principal investigator-level scientists and educators.

William Welch. What were the driving factors that led up to this day? Who would have thought that a simple two hour drive to Sacramento would lead to this? Humans are already able to model some quite complex phenomenon, such as the climate.
More intelligent civilisations, however, may be able to simulate living things — with actual consciousnesses — or even entire worlds or universes. Maybe we are no more than a bit of entertainment for some supreme being who is running such a model? Indeed, if life is destined to be able to create technologically advanced civilisations that can make computer programs, there may be more simulated universes our there than real ones out there — making it conceivable that we are in one of them.
This conjecture may sound outlandish, but it is all based on our current understanding of physics and cosmology. That would lead to even more jaw-dropping possibilities. Ultimately, physical reality could encompass complexities that neither our intellect nor our senses can grasp.

Martin Rees , University of Cambridge. The question of whether or not we are alone in the universe lies at the heart of many reasons we explore space. For more than half a century, one branch of science has tried to directly answer the question by searching for signals from intelligent beings. The past, present and future of SETI, the search for extraterrestrial intelligence. In a pre-Internet era where most Americans only had a few channels, Sagan and Carson spent 15 minutes on prime-time television discussing everything from Star Wars "I felt very bad that, at the end, the Wookiee didn't get a medal," Sagan said to how aliens might send us a signal using prime numbers.
These projects were led by Paul Horowitz, a Harvard physicist and electrical engineer.
