For decades, humans have been scanning the skies to find anything that can prove the existence of another life in our galaxy. Countless people have tried to establish evidence with sightings of UFOs (unidentified flying objects) to others trying to break into Area 51, long rumoured to house US government secrets about alien life.
Just recently we heard of study published by??The Astrophysical Journal,? which says that aliens not only exist but that there is?specific number of alien civilisations which is, 36 in our Galaxy alone.?
The online journal published metrics and approaches that went into guessing just how many alien societies are capable of interstellar messaging (a group known as Communicating Extraterrestrial Intelligent civilizations, or CETI).
Taking things on the alien life front to the next level, NASA is now funding?a group of astronomers to search the Universe for signs of alien civilizations via ¡°technosignatures¡±.?
Researchers technosignatures identifiable on Earth will also be identifiable in some way outside of the solar system.
¡°Technosignatures relate to signatures of advanced alien technologies similar to, or perhaps more sophisticated than, what we possess,¡± said Avi Loeb, Frank B Baird Junior Professor of Science at Harvard, reports ANI.?
¡°Such signatures might include industrial pollution of atmospheres, city lights, photovoltaic cells (solar panels), megastructures, or swarms of satellites.¡±
Avi Loeb, Professor of Science at Harvard. said, ¡°The nearest star to Earth, Proxima Centauri, hosts a habitable planet, Proxima b. The planet is thought to be tidally locked with permanent day and night sides."
The study, ¡°Characterising Atmospheric Technosignatures,¡± will initially focus on searching for two particular signatures that may indicate the presence of technological activities on extrasolar planetary bodies: solar panels and pollutants.
¡°My hope is that using this grant, we will quantify new ways to probe signs of alien technological civilizations that are similar to or much more advanced than our own,¡± said Loeb. ¡°The fundamental question we are trying to address is: are we alone? But I would add to that: even if we are alone right now, were we alone in the past?¡±?
This is the first NASA non-radio technosignature grant ever awarded and represents an exciting new direction for the search for extraterrestrial intelligence (SETI).?
