The discovery images of 2012 VP113. Three images of the night sky, each taken about two hours apart, were combined into one. The first image was artificially colored red, the second green, and the third blue. 2012 VP113 moved between each image as seen by the red, green, and blue dots. The background stars [...]
A Hubble Space Telescope image of Pluto and some of its moons. The New Horizons mission is just a year away from providing us with photographs that will greatly surpass the best images of Pluto that Hubble could ever capture. Image Credit: NASA, ESA, H. Weaver (JHU/APL), A. Stern (SwRI), and the HST Pluto [...]
Two newly discovered moons orbiting Pluto have been given official names by the International Astronomical Union. Image Credit: NASA / STSci
Two of Pluto’s small moons, previously known just as P4 and P5, have been given official names by the International Astronomical Union (IAU). Pluto is the god of the underworld in classical mythology, [...]
Neptune’s largest moon, Triton, seen here in an image from the Voyager 2 flyby, is thought to be a captured Kuiper Belt Object. Photo Credit: NASA.
Starting at about the orbit of Neptune and stretching out to roughly 50 astronomical units (1 AU = Earth-Sun distance), or 7.5 billion kilometers from the Sun, is [...]

The Lunar Atmosphere and Dust Environment Explorer (LADEE) is due for launch in September 2013 from the Mid-Atlantic Regional Spaceport. LADEE will study the composition and structure of the tenuous lunar atmosphere, including dust that may be lofted up from [...]
NASA’s first mission to the dwarf planet Pluto is two years away from its destination. Image Credit: NASA, ESA, and M. Buie Southwest Research Institute
Something odd happened a few months after NASA’s deep space probe New Horizons was launched Jan. 19, 2006—its target got demoted from a planet to a “dwarf planet.” In [...]
This false-color composite image, taken with the Hubble Space Telescope, reveals the orbital motion of the planet Fomalhaut b. Based on these observations, astronomers calculated that the planet is in a 2,000-year-long, highly elliptical orbit. The planet will appear to cross a vast belt of debris around the star roughly 20 years from now. [...]

Scientists working with data from both NASA’s Spitzer Space Telescope and the ESA’s Herschel Space Observatory have confirmed the detection of an asteroid-belt-like debris belt around the nearby star Vega.
