Scientists have not yet found direct evidence of a moon outside our solar system -- but they just found a hint of a hellish ...

By analyzing the movements of a mysterious cloud of sodium moving around the planet WASP-49 b, the team was able to construct a compelling argument for the presence of an exomoon. While many ...

NASA scientists have uncovered new evidence of a hellish, volcanic "exomoon" orbiting a superheated alien world relatively ...

Kipping and his team have succeeded in getting some JWST observation time to look for an exomoon. Back in February, his ...

And how do we know that the sodium is from an exomoon? The exoplanet is a gas giant, unlikely to host volcanoes – and the ...

A sodium cloud detected in the vicinity of WASP-49 b hints at the presence of a natural satellite, also known as an exomoon. While earlier studies have identified multiple exomoon candidates ...

We just called it “the Moon,” but other planets have moons too. Recently, the first evidence of an exomoon — that is, a moon orbiting a planet in another star system — was revealed ...

This "exomoon" is not like any in our cosmic neighbourhood: it's the size of Neptune and orbits a planet the size of Jupiter - but with 10 times the mass. The object was spotted in data from Nasa ...

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 ...

“I would say that the sodium signal is definitely intriguing, given the way it seems to dance around the planet, and that an exomoon is an exciting possibility,” said Jessie ...
