SUNSET: 
Dawn Sees Ceres Bright Spots and More
New results from the Dawn orbiter show bright spots, a pyramid-shape mountain, and mysterious haze on the dwarf planet Ceres.
Kapteyn b: Exoplanet or Illusion?
Recent research casts doubt on whether nearby Kapteyn b, a supposed super-Earth circling in its star’s habitable zone, is a planet at all.
Potential Mid-size Black Hole Found
Scientists have found what seems to be an intermediate-mass black hole in a spiral galaxy 100 million light-years away. If its size is confirmed, it could provide much-needed insight into black hole evolution.
The Long-Lived Magnetic Fields of Meteorites
The magnetic fields in the asteroid parent bodies of two pallasite meteorites lasted hundreds of millions of years after our solar system’s formation.
Rosetta Update: Philae Landed in a Hole
The exact location of Philae’s landing site remains unknown, though the site’s topography might allow the lander to operate longer than planned. Meanwhile, Rosetta is detecting organics and heavy elements even when Comet Churyumov-Gerasimenko is far from the Sun.
The 2014 Autumnal Equinox Arrives
Astronomically speaking, the fall season comes to the Northern Hemisphere on Tuesday, September 23, 2014 at 02:29 UTC (Monday, September 22 at 10:29 p.m. EDT). At that moment, the Sun passes over the Earth’s equator heading south; this event is called the autumnal equinox.
Rosetta Catches Its Comet
On August 6th, the ESA's Rosetta spacecraft finally completed its decade-long voyage to Comet 67P/Churyumov-Gerasimenko.
Pro-Am Collaboration Yields Stunning Images
Amateur astronomers have teamed up with the pros to produce four stunning multiwavelength images of galaxies M101, M81, M51, and Centaurus A.
Opportunity Rover Gets a Cleaning
The Mars rover Opportunity has been cleaned of heavy dust coating its solar panels, thanks to some strong winds blowing over the rim of Endeavour Crater.
Dust in the Heart of Circinus
Infrared observations of the Circinus Galaxy may help reveal the shape of the dusty region fueling its active galactic nucleus and shed light on what governs dust structures in other galaxies.
Interactive Mosaic of Moon's North Pole
With the first interactive lunar north pole mosaic released by the NASA’s Lunar Reconnaissance Orbiter Camera team you can explore an area of the Moon’s northern hemisphere about the size of Alaska and Texas combined.
Hubble Displays Galactic Jellyfish
These stunning new images of spiral galaxy ESO 137-001 highlight its violent encounter with the intracluster plasma of Abell 3627, which is stripping away its gas and forming stars in the streamers.
Rocky Encounter with Stellar Lighthouse
Asteroid debris might be bombarding a radio pulsar in the constellation Puppis.
Red Sky for Brown Dwarf
Astronomers have discovered a new “failed star” with unusually red, dusty skies. The dust makes the object look much younger than it actually is, complicating studies of this type of brown dwarf.
Mixed Message from Asteroid Belt
New compositional map of the main asteroid belt shows that minor planets are not strongly grouped by composition, as had been thought, but instead are mixed up.
Sleep of Death for China's Lunar Rover?
Reports suggest that something went wrong as the Yutu rover prepared to hibernate through the long lunar night. The glitch could be the end of the little robot.
New View of Lagoon Nebula
A new image of the Lagoon Nebula from the Paranal Observatory in Chile provides a stunning view the iconic object, which lies 5,000 light-years from Earth in Sagittarius.
The End of Rosetta's Big Sleep
Europe's comet-chasing spacecraft woke up after a 957-day-long hibernation to begin the most comprehensive comet study to date. Part of its mission: attempt to place an instrumented lander on a comet’s nucleus for the first time.
Gaia Launches to Pinpoint a Billion Stars
Gaia launched flawlessly Thursday morning at 9:12 UTC (4:12 a.m. Eastern Standard Time). This long-awaited mission will precisely map the distances and motions of 1 billion stars in our galaxy.
Comet ISON: What We've Learned
Comet ISON's untimely demise didn’t prevent scientists from studying it, revealing the comet to be smaller than previously thought and harboring high concentrations of carbon.
