Image 1 - Dawn Now In Its Lowest Orbit Around Vesta
2011-12-13 04:25:18

NASA's Dawn spacecraft successfully maneuvered into its closest orbit around the giant asteroid Vesta on Monday, Dec. 12, beginning a new phase of science observations. The spacecraft is now circling Vesta at an altitude averaging about 130 miles (210 kilometers) in the phase of the mission known as low altitude mapping orbit. "Dawn has performed some complicated and beautiful choreography in order to reach this lowest orbit," said Marc Rayman, Dawn chief engineer and mission manager based...

Dawn Reveals Vesta's 'Color Palette'
2011-12-07 05:46:54

[ Watch the Video ] Vesta appears in a splendid rainbow-colored palette in new images obtained by NASA's Dawn spacecraft. The colors, assigned by scientists to show different rock or mineral types, reveal Vesta to be a world of many varied, well-separated layers and ingredients. Vesta is unique among asteroids visited by spacecraft to date in having such wide variation, supporting the notion that it is transitional between the terrestrial planets -- like Earth, Mercury, Mars and Venus --...

Dawn Provides New 3D Views Of Asteroid Vest

[ Watch the Video ] Glide over the giant asteroid Vesta with NASA's Dawn spacecraft in a new 3-D video.  Dawn has been orbiting Vesta since July 15, obtaining high-resolution images of its bumpy, cratered surface and making other scientific measurements. The new video is best viewed with red-blue glasses, and incorporates images from Dawn's framing camera from July to August 2011. It was created by Dawn team member Ralf Jaumann of the German Aerospace Center (DLR). The images...

Image 1 - Astronomers Size-Up Dwarf Planet Eris

[ Watch the Video ] The European Southern Observatory (ESO) announced on Wednesday that astronomers have accurately measured the diameter of the dwarf planet Eris for the first time. The astronomers believe that the dwarf planet is an almost perfect twin of Pluto in terms of size.  The planet, according to ESO, appears to have a reflective surface, which suggests it is uniformly covered in a thin layer of ice. Astronomers made observations as Eris passed in front of a faint...

NASA's Dawn Science Team Presents Early Science Results
2011-10-13 10:19:27

Scientists with NASA's Dawn mission are sharing with other scientists and the public their early information about the southern hemisphere of the giant asteroid Vesta. The findings were presented today at the annual meeting of the Geological Society of America in Minneapolis, Minn. Dawn, which has been orbiting Vesta since mid-July, has found that the asteroid's southern hemisphere boasts one of the largest mountains in the solar system. Other findings show that Vesta's surface, viewed by...

Dwarf Planet Mysteries Beckon To New Horizons
2011-09-04 05:42:58

  At this very moment one of the fastest spacecraft ever launched -- NASA's New Horizons -- is hurtling through the void at nearly one million miles per day.  Launched in 2006, it has been in flight longer than some missions last, and still has four more years of travel to go. New Horizons headed for the lonely world of Pluto on the outer edge of the solar system. Although astronomers now call Pluto a dwarf planet, "it's actually a large place, about 5,000 miles around at...

  Scientists at the California Institute of Technology (Caltech) have discovered that a dwarf planet at the edge of the solar system, dubbed 2007 OR10, is an icy world with about half its surface covered in water ice that once flowed from ancient, slush-producing volcanoes. The red-tinged planet, nicknamed Snow White, may also be covered in a thin layer of methane, the last remnant of an atmosphere slowly being dissipated into space, astronomers said. "You get to see this nice...

WASHINGTON, Aug. 1, 2011 /PRNewswire-USNewswire/ -- 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...

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...
