The 'moment of truth is about to arrive,' says UCLA's Christopher Russell.
A British-based team of astronomers has discovered carbon monoxide gas in the atmosphere of Pluto, after a worldwide search lasting for nearly two decades.
After 3 and a half years of thrusting silently through the void, NASA's Dawn spacecraft is on the threshold of a new world.
NASA's Hubble Space Telescope has captured images of the large asteroid Vesta that will help scientists refine plans for the Dawn spacecraft's rendezvous with Vesta in July 2011.
Beyond the orbit of Neptune reside countless icy rocks known as trans-Neptunian objects (TNOs).
Let the countdown begin. NASA's Dawn spacecraft is less than one year away from giant asteroid Vesta.
Engineers are studying the reaction wheels on NASA's Dawn spacecraft after automatic sensors detected excess friction building up in one of them and powered it off early on the morning of June 17, 2010.
A large group of scientists, including Jay Pasachoff, Bryce Babcock, and Steven Souza at Williams College, reveal the character of one of the most distant objects in the solar system in a scientific paper which appeared in the June 17 issue of the journal Nature.
Until now, astronomers have used telescopes to find Kuiper Belt objects (KBOs), moon-sized bodies, and obtain their spectra to determine what types of ices are on their surface.
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...
