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.

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, [...]

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.

According to the New Horizons’ twitter feed, @NewHorizons2015, and Principal Investigator Alan Stern, the New Horizons probe will make a long-range encounter with a Kuiper Belt Object in January 2015. The [...]
