Astronomers have identified signals emitted by what they believe is the first moon discovered outside our solar system.
The discoveries are tempting but the celestial body is far from being directly observed.
Details of the discovery were published in the scientific journal ‘Nature Astronomy’. The moon appears to orbit a star about 5,500 light-years away from Earth and has been named Kepler-1708 bi.
If the data obtained by the Kepler telescope is already out of service, the newly discovered moon could be 2.6 times larger than the earth and composed of gas.
Scientists have confirmed the existence of about 5,000 planets outside our solar system, otherwise known as exoplanets. But so far only exo-moons, including the Kepler-1708 bi, have been identified. The first was discovered in 2017; but there are still doubts about its existence.
Seeing the great distance between our solar system and these moons, it is not possible for them to be seen directly.
Astronomers often rely on circumstantial evidence such as regular variations in the light emitted by exoplanets, otherwise known as transit arcs of light.
Researchers say that exo-moons are different from the moons observed in the solar system, both in terms of their formation process and orbital motifs.
