SUNSET: 
Pulsars' Gamma Rays Highlight Mysteries
The Fermi Gamma-ray Space Telescope has discovered that almost all of the highest energy photons in the Large Magellanic Cloud come from two pulsars.
Mars Losing Gas to Solar Wind
NASA’s Mars orbiter MAVEN has painted a detailed picture of how the solar wind robs the Red Planet of its atmosphere.
How a Black Hole Flares
X-ray observations suggest that flares happen when a black hole's "atmosphere" contracts and launches away from it.
Cassini Flies Through Enceladus's Plume
On October 28th, the Cassini spacecraft took its deepest dive through the water plume spewing from the south pole of Saturn’s moon Enceladus. It passed only 30 miles (50 kilometers) above the icy surface.
White Dwarf Eats Mini Planet?
Astronomers have detected debris around a white dwarf that might be from one or more disintegrating rocky planets.
Closest Star-shredding Black Hole
The last hurrah of a star wrenched apart by a supermassive black hole tells astronomers what the stellar crumbs are doing.
False-color Maps of Ceres
New maps from NASA’s Dawn spacecraft reveal more about both the landscape and composition of the largest asteroid.
Waterlogged Salts on Mars
Scientists have confirmed that water-soaked salts likely create dark seasonal lines on Mars.
New Mid-size Black Hole
Astronomers think a bright X-ray source in the galaxy NGC 1313 is a mid-size black hole.
New Evidence for Black Hole Binary
Astronomers have confirmed that the quasar PG 1302-102 is probably a binary supermassive black hole, its members less than a tenth of a light-year apart.
Resonant Waves Might Heat Corona
Astronomers have detected waves working together in the solar atmosphere, potentially heating the gas through turbulence.
New View of Ceres’ Amazing Spots
The latest image from NASA's Dawn spacecraft reveals structure in the bright spots on the asteroid 1 Ceres.
Microlensing Exoplanet Confirmed
Astronomers have confirmed the existence of an exoplanet found via microlensing — the first time they’ve been able to successfully follow up on this method.
Aurora on a Dwarf Star
Astronomers have detected what looks like auroral emission on an ultra-cool star.

Rosetta Spots Sinkholes on Comet
The spacecraft orbiting Comet 67P/Churyumov-Gerasimenko has found 18 holes in the nucleus's surface.
The Glint of Martian Glass
Scientists have detected glass in Martian craters, created by the fierce heat of impacts that melted the Red Planet’s surface.
Asteroid Tour: Fly Over Ceres
Visit the dwarf planet Ceres in this video animation created from images taken by NASA’s Dawn spacecraft.
Supernova, Two Ways
Two new studies confirm that the white dwarfs that explode as Type Ia supernovae can approach death in two different ways.
