Extraterrestrial Life May Be Discovered in the Next 20 Years

Extraterrestrial Life

The Search for Extraterrestrial Intelligence (SETI) astronomers explained to a committee on May 21 that extraterrestrial life may be discovered within the next 20 years. Seth Shostak, a senior astronomer from the SETI institute in California, said that numerous plans have the future potential to find signs of other life on planets in the far distance.

Shostak went on to explain that, at the very least, there are several additional worlds in space that may have extraterrestrial life in the Earth’s galaxy. The odds of them discovering it are high and should happen in around 20 years. However, like many other projects, the speed of all of this will depend on the missions’ financing.

SETI explained that they have established specific ways of reaching these goals. It is reported that they will probably detect extraterrestrial life in one of a few different ways. One route is to find microbial life within the Earth’s solar system. Another is detecting signals from distant areas in space. The last is analyzing the production of oxygen and methane in the surrounding exoplanets.

The astronomers expect to find alien life by searching for any hints of oxygen or methane in the surrounding atmosphere of planets outside of the Earth’s solar system. Oxygen and methane are frequently accompanied by some sort of evidence of life nearby. Shostak explained that this method could be verified soon by discovering extraterrestrial life.

Another tactic SETI will use for pinpointing other signs of life is intercepting the signals released by far off planets, whether they may be deliberately or unintentionally sent. Alien life might have the ability to transmit radio waves and other wavelengths into the universe and help them discover extraterrestrial life in the next 20 years.

Dan Werthimer, the director, explained that a few of the Earth’s oldest shows on television, such as The Ed Sullivan Show and I Love Lucy have interacted with thousands of stars. Shostak further explained that capturing signals from other sources may have good outcomes because after inventing a simple radio, the people now have the technology which could send small morsels of information through many light years of space to possible extraterrestrials. For Werthimer, it would be bizarre if they never found any signs of other life. Earth cannot be completely alone.

Although no such evidence has been discovered yet, all of the astronomers remained extremely optimistic. With advances in technology booming in the past couple of years, there is a high potential now for finding other life in space. With all of these tactics in place, they plan on using them and discovering new information about this subject in the next couple years.

Werthimer explained to the House Science and Technology Committee that since neighboring stars have received signals from shows like The Simpsons, then maybe other extraterrestrial life is sending its own signals toward Earth. Shostak believes that just because they haven’t discovered any signs of extraterrestrial life, they have only just started. In the next 20 years, evidence of extraterrestrial life may be found.

    ETs more likely use quantum than radio wave communications, so that SETI’s searching via waves is unlikely to find anything.

    stupid uninformed speculation. where have all the real scientists gone?
