A new haul of objects closer to home have been found by astronomers looking through the data from the Sloan Digital Sky Survey.A team led by Dr. Andrew Becker, of the University of Washington, has discovered almost 50 new asteroid-sized bodies in the outer regions of our Solar System by searching through a survey region known as Stripe 82.The robotic Sloan telescope in New Mexico revisited this area of the southern sky every three days in a search of supernovae.  By comparing images...

A huge comet-like object has been spotted inside the orbit of Neptune. The object, at least 30 miles wide, is on the return leg of a 22,500-year journey around the sun, astronomers announced today. Catalogued as 2006 SQ372, the interloper is just over two billion miles (3.2 billion km) from Earth, though its elongated trek takes it to a distance of 150 billion miles (241 billion km), or nearly 1,600 times the distance from the Earth to the sun. The only known object with a...

An icy, unknown world might lurk in the distant reaches of our solar system beyond the orbit of Pluto, according to a new computer model. The hidden world -- thought to be much bigger than Pluto based on the model -- could explain unusual features of the Kuiper Belt, a region of space beyond Neptune littered with icy and rocky bodies. Its existence would satisfy the long-held hopes and hypotheses for a "Planet X" envisioned by scientists and sci-fi buffs alike. "Although the search for a...

NEWPORT BEACH, CA -- The Binary Research Institute (BRI) has found that orbital characteristics of the recently discovered planetoid, "Sedna", demonstrate the possibility that our sun might be part of a binary star system. A binary star system consists of two stars gravitationally bound orbiting a common center of mass. Once thought to be highly unusual, such systems are now considered to be common in the Milky Way galaxy. Walter Cruttenden at BRI, Professor Richard Muller at UC Berkeley,...

WASHINGTON (Reuters) - A distant object named Buffy has been spotted circling the sun far beyond Neptune in a strange tilted orbit that is making some astronomers question how the outer reaches of the solar system formed. Officially called 2004 XR 190 by the International Astronomical Union but code-named Buffy, the object is now about 58 times as far from the sun as Earth, and twice as far from the sun as Neptune. At this distance from the heart of the planetary system, Buffy is a considered...

Gemini -- Recent spectroscopic studies of infrared light reflected from the surface of Sedna reveal that it is probably unlike Pluto and Charon since Sedna's surface does not display evidence for a large amount of either water or methane ice. Due to Sedna's extreme distance from the Sun, the frigid surface has probably been untouched for millions of years by anything except cosmic rays and solar ultraviolet radiation. Gemini Observatory astronomer Chad Trujillo led an effort by the same...

Cambridge, MA -- When the distant planetoid Sedna was discovered on the outer edges of our solar system, it posed a puzzle to scientists. Sedna appeared to be spinning very slowly compared to most solar system objects, completing one rotation every 20 days. Astronomers hypothesized that this world possessed an unseen moon whose gravity was slowing Sedna's spin. Yet Hubble Space Telescope images showed no sign of a moon large enough to affect Sedna. New measurements by Scott Gaudi, Krzysztof...

Close encounter may explain some objects beyond Neptune Cambridge, MA -- A hit TV program like "Antiques Roadshow" lures viewers with its universal appeal. Who wouldn't want to find secret riches in their attic or basement? But rare paintings and heirloom jewelry aren't the only valuable items waiting to be discovered. Cosmic treasures also lay hidden in the vast realm of outer space. Among the most highly prized of those treasures are planets that formed around other stars. Astronomers have...
