Astronomers have reported a second, super-sized moon orbiting a Jupiter-sized planet outside our solar system, and if confirmed, this view could mean that “exomoons are as common in the universe as exoplanets, and that these large or small moons are a feature of planetary systems.” ». The discovery, which was published yesterday in the journal Nature Astronomy, was led by David Kipping and his Kool Weld Lab at Columbia University, which reported the first exoplanet candidate in 2017. Says Kipping, who has spent the past decade searching for exomoons in A report published by the Columbia University website in conjunction with the study’s publication, “Astronomers have discovered more than 10,000 candidate exoplanets so far, but exomoons present a much greater challenge…It is uncharted territory.”
The team discovered the new giant moon orbiting the planet (Kepler 1708b), a world 5,500 light-years from Earth in the direction of the planets “Signa” and Lyra, and this new candidate is about a third smaller than the size of the previous moon, equal to the size of Neptune, which Kepping and colleagues found in An earlier time orbiting the planet “Kepler 1625 b” similar to the size of Jupiter. Kipping says that both candidates for the giant moon are likely made of gas accumulating under the gravitational force of their enormous size, which means, if this hypothesis for astronomers is correct, that the moons began their lives as planets, only to be pulled into the orbit of a larger planet like « Kepler 1625b or 1708b.
The outer moons fascinate astronomers for the same reasons that the outer planets do, as they have the ability to reveal how and where life arose in the universe, and these moons in themselves are curious, astronomers want to know how these outer moons formed, and whether they could sustaining life, and what role, if any, it plays in making the host planets habitable.
