 | Chondritic meteorites have a similar chemical composition to the sun and are therefore reliable witnesses as to what the solar nebula, from which the planets formed, was composed of ...> Full Article |
 | scientists are designing a satellite-based observatory that they say could for the first time provide a sensitive survey of the entire sky to search for planets outside the solar system that appear to cross in front of bright stars. The system could rapidly discover hundreds of planets similar to the Earth. ...> Full Article |

Interstellar space may be strewn with tiny whiskers of carbon, dimming the light of far-away objects. This discovery by scientists at the Carnegie Institution may have implications for the "dark energy" hypothesis, proposed a decade ago in part to explain the unexpected dimness of certain stellar explosions called Type1a supernovae.

 | Using data from NASA's Chandra X-ray Observatory, scientists have reported the possible detection of a binary star system that was later destroyed in a supernova explosion. The new method they used provides great future promise for finding the detailed origin of these important cosmic events. ...> Full Article |
 | An international team of astronomers has discovered two planets that resemble smaller versions of Jupiter and Saturn in a solar system nearly 5,000 light years away. ...> Full Article |
 | First results from a new NASA-funded scientific instrument at the W. M. Keck Observatory in Hawaii are helping scientists overturn long-standing assumptions about powerful explosions called novae and have produced the first unified model for a nearby nova called RS Ophiuchi. ...> Full Article |
 | Astonomers determine order of planets past, present, and possibly future. ...> Full Article |
 | Researchers have dated the earliest step in the formation of the solar system -- when microscopic interstellar dust coalesced into mountain-sized chunks of rock -- to 4,568 million years ago, within a range of about 2,080,000 years. ...> Full Article |
 | Scientists have discovered that our sun's 'atmosphere' is asymmetric, thanks to two champion spacecraft. ...> Full Article |
 | NASA's Voyager 2 spacecraft has followed its twin Voyager 1 into the solar system's final frontier, a vast region at the edge of our solar system where the solar wind runs up against the thin gas between the stars. ...> Full Article |
 | The Voyager 2 spacecraft's Plasma Science instrument, developed at MIT in the 1970s, has turned up surprising revelations about the boundary zone that marks the edge of the sun's influence in space. ...> Full Article |
 | Astronomers at the University of Illinois have found the first clear evidence for a cradle in space where planets and moons form. The cradle, revealed in photographs taken with NASA's Spitzer Space Telescope, consists of a flattened envelope of gas and dust surrounding a young protostar. ...> Full Article |
 | Using a computer model simulation, Haruichi Washimi, a physicist at UC Riverside, has predicted when the interplanetary spacecraft Voyager 2 will cross the "termination shock," the spherical shell around the solar system that marks where the solar wind slows down to subsonic speed. ...> Full Article |
 | Astronomers have found what are believed to be some of the youngest solar systems yet detected. ...> Full Article |
New research led by a University of St Andrews astronomer has found evidence for what might be the raw material for the beginning of shrunken versions of our solar system - miniature worlds in the making.

A new astronomical study adds an unexpected twist to the complications: stars well-endowed with gold and other heavy elements have fewer stellar companions. Researchers believe their discovery could help track down Earth-like planets outside of our solar system.

 | As reservoirs of valuable information go, nothing beats the sun. This sphere of heat and energy holds 99.9 percent of the solar system, saved in all original proportions after planets and meteorites formed. Analyzing the mix of hydrogen, oxygen and noble gases found in the sun can answer one of the biggest questions of the universe: How did our solar system evolve? ...> Full Article |
Comet 17P/Holmes may be old, but it can still kick up its heels and go dancing with the stars! It was discovered more than 100 years ago, and since then has made 16 loops around the Sun. It should have fizzled long ago, but just this week Comet Holmes surprised sky watchers with a stunning outburst, becoming brighter than any comet in the past decade.

 | Ancient explorers set sail expecting to encounter dragons on the world's unknown oceans. NASA's twin Voyager spacecraft are searching for dragons of a different sort as they enter the boundary of our solar system â€" cosmic "dragons" that breathe a strange fire of high-speed atomic fragments called cosmic rays. ...> Full Article |
