Here’s how it works. NASA scientists have uncovered new evidence of a hellish, volcanic "exomoon" orbiting a superheated alien world relatively close to Earth. The proposed satellite ...

An exomoon, a companion to an exoplanet, likely would be too tiny and far away for telescopes to resolve. But a new NASA study may have found a clue that one is orbiting a planet some 635 light ...

Another potential exomoon was discovered a year later by the same team, this time around exoplanet Kepler-1708 b. Both candidate moons are huge, bigger than half the planets in the Solar System ...

In 2017, the astronomy world was abuzz at the announcement that exoplanet Kepler-1625b potentially had its own moon—an exomoon. This was the first hint anyone had seen of an exomoon, and was ...

It’s only the second space object discovered that may be an exomoon, or a moon outside of our solar system. The giant moon was found orbiting a Jupiter-size planet called Kepler 1708b ...

Astronomers think they've found an 'exomoon' – a moon that exists outside our own solar system – based on data from NASA's Kepler space telescope. In a new paper, the experts report the ...

Some of the same researchers who found the first purported exomoon now say that they’ve found another. Dubbed Kepler 1708 b i, the satellite has a radius about 2.6 times that of Earth ...
