Over the past decade, there has been a tremendous amount of effort to find intelligent alien life on exoplanets, i.e., other planets out of our solar system.
The 2009 launching of NASA’s Kepler telescope boosted the hunting of the new planets. Primarily designed to be used for the finding of exoplanets, Kepler is also used to search for inhabited planets by making use of a technique named dimming of starlights. Using this technique, Kepler tracks stars that have regular light dimming with the assumption that the dimming of a starlight maybe due to the orbital motion of a planet around the host star.
Over the past 7 years, Kepler has succeeded to discover over 1000 distant stars with planets crossing the face of their parent stars and, therefore, leading to the regular dimming of their light. During this investigation, the stars were randomly chosen and monitored and based on their light pattern were selected as the ones having planets.
While the current method has led to a number of good candidates for the existence of extraterrestrial life; however, since the stars were chosen randomly, it has not been able to provide a satisfying result for proving of intelligent alien life making the outlook for a definite answer a far-reaching one.
In order to resolve this problem, a new technique that may lead to a breakthrough in the research has recently been suggested by two astronomers working at Max Planck Institute for Solar System Research in Göttingen, Germany. In an article to be published in the April issue of journal Astrobiology, Dr. René Heller and his associate Ralph Pudritz from McMaster University in Hamilton, Canada, suggests that the search should be focused on what is called Earth’s transit zone. Their idea is quite simple but may lead to a strong push in the quest for the alien hunting.
Their method is based on narrowing down the search area to the areas in which potential alien astronomers can use the dimming of light technique to discover us on the Earth.
