Alien life 'hiding' on the moons far from us?

Scientists say it has identified more than 100 giant planets outside the Solar System that most likely contain life-producing moons.

"There are currently 175 moons known to orbit the eight planets in our Solar System , " said Stephen Kane, a professor at the University of California, Riverside, in a paper published in the Astrophysical Journal.

"While most of these satellites orbiting Saturn and Jupiter - outside of the Sun's habitable zone, in other solar systems things may not be," Kane said.

Along with researchers from the University of Southern Queensland in Australia, Professor Kane's team identified 121 giant planets that have orbits within the habitable regions of their stars.

At three times the size of the Earth, these planets are less common than the earth planets (rocks) but are expected to have many large moons, including rocky moons that can contain life.

According to Science Daily, since NASA's Kepler telescope went into operation in 2009, scientists have identified thousands of exoplanets known as extrasolar planets.

Kepler's main task is to identify planets within the livable regions of their stars - meaning that it is not too hot or too cold for liquid water - and is capable of survival.

The primary goal of the search for extraterrestrial life is the earth planets (rocks), because some of them may be similar in geology and atmosphere to Earth. Another place also considered by scientists is giant gas planets.

Although not a candidate on the journey to search for life, Jupiter-like planets are also expected to contain rocky moons - known as the moon, which can support life.

Scientists speculate that moon moons can provide a favorable environment for life, even better than Earth. However, no moon has been confirmed so far.

The findings of American and Australian scientists are expected to pave the way for the design of future telescopes to help find potential extraterrestrial moons and search for signs of life, called biosignature. , in their atmosphere.
