Researchers to take help of AI inspired by human neural network to find extraterrestrial life

AI marking its footsteps over Human Intelligence in 2017

Holla! Artificial Intelligence (AI) has found a room for itself in astroscience! The biggest boom that technology has ever experienced is none other than the Artificial Intelligence (AI). And the very idea of AI is intelligence stimulation in lifeless machines.

Development in artificial intelligence (AI) has ignited the spark of ‘probability of life’ beyond Earth. Yes, with ‘probability of life’ on other planet, we all can well relate to the most curiously sought-after species i.e. alien! Alien was a thing of past until astrologers had devised ways to predict the presence of life forms beyond Earth.

Researchers at Plymouth University in the UK used Artificial Neural Networks (ANNs) for exploration of life in other planets. “We are currently interested in these ANNs for prioritizing exploration for a hypothetical, intelligent, interstellar spacecraft scanning an exoplanet system at range,” said Christopher Bishop, from the varsity.

ANNs represent incredibly exciting and powerful machine learning techniques that attempt to replicate human behavior. Inspired by the central nervous system of a human body, these networks act as an information processing technique that mimics the human behavior. These systems ‘learn’ tasks by considering examples.

“We also consider the use of large area, deployable, planar Fresnel antennas to recover data from an interstellar probe over long distances to Earth, which would be required if the technology is used in future on robotic spacecraft.” Bishop said. The atmospheric observation, known as spectra, done by the researchers are experimented with the ANNs as inputs and are asked to classify based on their closeness to today’s Earth, early Earth, Mars, Venus or Saturn’s moon ‘Titan’. The team had trained the networks to classify the signals based on the above five planets wherein all the suitable potential habitable objects are present.

Undoubtedly, ANNs stands as the foundation for the entire enigma of alien sciences. The unveiling of this technique will hugely help in keeping track for future observations and selecting targets, provided further detailed spectral research is done by upcoming space missions such as European Space Agency’s Ariel Space Mission and NASA’s James Webb Space Telescope.

The work was presented at the European Week of Astronomy and Space Science (EWASS) in Liverpool.
