SUNSET: 
Astronomers Find Hints of an Exomoon
Astronomers might have found a moon half the mass of Jupiter orbiting in a nearby system, based on the wobbles of its host world.
Doubt Cast on Exomoon Candidates
Exomoon candidates are tantalizing but, according to new research, perhaps unfounded.
Needle in the Haystack: New Exomoon Candidate Found
Astronomers may have found a second Neptune-size exomoon hidden in the retired Kepler space telescope’s data.
Astronomers Detect Potential Moon-forming Disk around an Exoplanet
Astronomers have made the first clear detection of a dusty disk surrounding an exoplanet, which could eventually go on to form moons.
Have Astronomers Detected Exomoons At Last?
Have astronomers detected two giant exomoons? The answer depends on how convincing you deem newly presented results — and how you define a moon.
Exomoon or No Exomoon?
Last October, the first discovery of a potential exomoon was announced. But is Kepler-1625b-i an actual moon in another solar system? Or just an artifact of data reduction?
Hubble Boosts Case for Exomoon
Exoplanet Kepler-1625b might harbor a moon the size of Neptune—potentially the first confirmed exomoon—but researchers urge caution.
Best Exomoon Candidate Yet?
Astronomers have found one of the best exomoon candidates in data collected by the Kepler spacecraft.
Help Astronomers Track a Giant, Ringed Planet
The possible discovery of a massive ringed planet in Orion needs confirmation — and amateur astronomers can help.
Gap Reveals Potential Exomoon
Astronomers have confirmed that the star J1407 seems to have a companion with a gigantic, gap-ridden ring, inside which an “exomoon” might be forming.
