NASA's Dawn spacecraft, the first ever to orbit an object in the main asteroid belt, is spiraling towards its first of four intensive science orbits. That initial orbit of the rocky world Vesta begins Aug. 11, at an altitude of nearly 1,700 miles (2,700 kilometers) and will provide in-depth analysis of the asteroid. Vesta is the brightest object in the asteroid belt as seen from Earth and is thought to be the source of a large number of meteorites that fall to Earth. The Dawn team has now...

Dawn took this image during its current orbit of Vesta, traveling from the day side to the night side. The large structure near the south pole that showed up so prominently in previous images is visible in the center of the illuminated surface. Compared to other images, this one shows more of the surface beneath the spacecraft in the shadow of night. Vesta turns on its axis once every five hours and 20 minutes. Dawn entered orbit around Vesta on July 15, 2011, and will spend a year orbiting...

NASA said on Wednesday that astronomers have discovered a fourth moon orbiting the dwarf planet Pluto. The new moon was uncovered while using the Hubble Space Telescope. "I find it remarkable that Hubble's cameras enabled us to see such a tiny object so clearly from a distance of more than 3 billion miles," Mark Showalter of the SETI Institute in Mountain View, Calif., who led this observing program with Hubble, said in a press release. NASA said the new moon has an estimated diameter of 8...

Uranus' moon Titania -- Titania is the largest moon of Uranus. Titania was discovered on January 11, 1787 by William Herschel. All of the moons of Uranus are named for characters from Shakespeare or Alexander Pope. Names for the first four discovered moons of Uranus, Oberon, Titania, Ariel and Umbriel, were given by John Herschel, the son of William. Titania was named after Titania, the Queen of the Faeries in A Midsummer Night's Dream. Titania is composed of roughly 50% water...

Brown Dwarf -- Brown dwarfs are a special type of low-mass star (approximately 13-70 Jupiter masses) that do not have nuclear fusion occurring in their cores during their time on the main sequence. Early in their development most brown dwarf stars do have lithium fusion in their cores, and a lack of lithium is a test for low-mass objects that are suspected of being brown dwarfs. Many brown dwarfs continue to glow in the red and infrared after their lithium is exhausted. This glow is...
