Andy Cheng has seen it all. The scientist from Johns Hopkins' Applied Physics Lab has worked on the Galileo mission to Jupiter, the Cassini mission to Saturn, the NEAR mission to asteroid 433 Eros and many others during his decades-long career. Alien vistas are old hat to him. But even he was amazed when he laid eyes on this photo of Io's Tvashtar volcano, taken Feb. 28th by the New Horizons spacecraft: Omigod! I can't believe it. "That was my first reaction," says Cheng. "The LORRI image of...

LAUREL, Md. -- NASA's New Horizon's space probe was pointed toward Pluto and the frozen, sunless reaches of the solar system on a nine-year journey after getting a gravity boost Wednesday from Jupiter. The fastest spacecraft ever launched was within a million and a half miles of Jupiter early Wednesday, giving scientists a close-up look at the giant gaseous planet and its moons. Mission managers at the Johns Hopkins Applied Physics Laboratory in Laurel, Md. waited for the first signals from...

A study of Pluto's bright frosts suggests that the way the planet cools down is rapid and disorganised. The results were presented at the European Planetary Science Congress in Berlin. Pluto's surface is bright because its atmosphere periodically condenses onto the surface. Theory suggested that, as Pluto cools, the traces of methane should condense first, followed by nitrogen ice as Pluto's surface grows colder.  The study showed two surprising results: that most of Pluto's nitrogen...

By Mike Collett-White VENICE -- British composer Colin Matthews has more reason than most to mourn the demotion of Pluto from planet to mere "dwarf planet." In 2000 he released "Pluto," an addition to Gustav Holst's famous seven-part orchestral suite "The Planets," which in 1917 included seven of eight officially recognized planets at the time. According to Matthews, Earth was not a part of the composition because it has no astrological significance, while Pluto was discovered four years...

If you woke up Thursday morning and sensed something was different about the world around you, you're absolutely right. Pluto is no longer a planet. The International Astronomical Union, wrapping up its meeting in Prague, Czech Republic, has resolved one of the most hotly-debated topics in the cosmos by approving a specific definition that gives our solar system eight planets, instead of the nine most of us grew up memorizing. NASA has already visited all eight planets that retain their...

By Alan Crosby PRAGUE (Reuters) - Pluto was stripped of its status as a planet on Thursday when astronomers from around the world redefined it as a "dwarf planet," leaving just eight major planets in the solar system. With one vote, toys and models of the solar system became instantly obsolete, forcing teachers and publishers to scramble to update textbooks and lessons used in classrooms for decades. "Pluto is dead," Mike Brown of the California Institute of Technology bluntly told...

By Alan Crosby PRAGUE (Reuters) - Pluto was stripped of its status as a planet on Thursday when astronomers from around the world redefined it as a "dwarf planet," leaving just eight classical planets in the solar system. Discovered in 1930, Pluto has traditionally been considered the ninth planet, and furthest from the sun, in the solar system. However, the definition of a planet approved after a heated debate among some 2,500 scientists from the International Astronomical Union...

By Bill Trott WASHINGTON (Reuters) - The American astronomer who put Pluto on the solar system map would have accepted its demotion to non-planet status because he was a good scientist, his widow said on Thursday. "Clyde said, 'Well, it's there. You can do what you want with it,"' Patricia Tombaugh, 94, said from her home in Las Cruces, New Mexico, after the International Astronomical Union downgraded husband Clyde Tombaugh's crowning achievement. Tombaugh was 24 years old and...

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...
