SUNSET: 
How Amateurs Could Help Future Exoplanet Observations
Large observatories will require precise timing info to measure as many exoplanet atmospheres as possible. Backyard astronomers have the power to keep that intel fresh.
Amateurs Help Decide Juno's Path
Ahead of a decision on whether to fly the NASA spacecraft over Jupiter's Great Red Spot, hobbyists back on Earth provided crucial intel about the effects of an intruding disturbance.
60-Second Astro News: Helium Exoplanets and a Supernova Surprise
This week in astronomy news: Inflated helium atmospheres surround two exoplanets, and the Kepler Space Telescope captures the moments around a supernova that hint at a companion star triggering the explosion.
60-Second Astro News: A Carnivorous Quasar and a Galaxy Ghost
In astronomy news this week: The most luminous quasar known in the cosmos is devouring three galaxy companions, while a newly discovered ghostly satellite of the Milky Way hints at hordes more just waiting to be found.
Amateur Planet Hunters Have a New Online Resource
A database run by the American Association of Variable Star Observers will organize and archive data on transiting exoplanets collected by amateur astronomers.
Puny Star Might Be Specimen from Early Universe
A low-mass sun with few elements heavier than helium provides hope that the Galaxy might contain survivors from the very first generation of stars.
Dwarf Galaxy Found by Amateur
Donatiello I is a tiny galaxy about 10 million light-years away, and it was discovered by an Italian hobbyist with a homemade telescope.
60-Second Astro News: Infant Superclusters and Wavering Gamma Rays
In astronomy news this week: A gargantuan supercluster of galaxies lurks in the early universe, while data from the Fermi telescope hint at two supermassive black holes locked in a gravitational dance.
Some Moons Could Have Moons of Their Own
Four solar system satellites — and one putative exomoon — are big enough and far enough from their home worlds to hold onto tiny moons for billions of years.
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.
60-Second Astro News: Dust Storms on Titan, Origin of Phobos
In astronomy news this week: Dust storms are seen blowing around Titan for the first time, and new clues from old data suggest that an impact on Mars gave birth to Phobos.
The Magellanic Clouds Might Once Have Been a Trio
The Milky Way's two largest companion galaxies may have once been a threesome — but new data from the Gaia satellite leaves the satellites' history an open question.
Sunspot Solar Observatory Reopens After Mysterious Shutdown
After a 10-day lockdown to cooperate with a criminal investigation, Sunspot Solar Observatory is back to looking at the Sun.
