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.
Volcanoes on a Super-Earth?
Observations of nearby super-Earth 55 Cancri e reveal huge, as-yet unexplained changes in the exoplanet’s infrared emission, and volcanoes are one possible cause.
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.
An Asteroid to Rule Them All
Scientists have new insight into the damage caused by a Rhode Island–size asteroid that hit Earth more than 3 billion years ago, making the rock that wiped out the dinosaurs look like a lightweight.
LADEE Skims the Moon Before Crash
NASA has a fully functioning spacecraft orbiting the Moon, all science goals completed, and a lunar eclipse coming up. It's a perfect opportunity to make some risky but potentially rewarding swoops within 2 miles of the lunar surface.
Brightest Mars in Six Years
Mars is making its nearest and brightest appearance in the night sky since the end of 2007.
Rosetta Spots Its Comet
The European Space Agency’s comet-chasing spacecraft has imaged its destination for the first time since waking up from 957 days of hibernation.
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.
New Splat on Mars
NASA’s Mars Reconnaissance Orbiter HiRISE camera captured this stunning image of a fresh impact on the Martian surface.
