Scientists have argued about the origins of Mercury's smooth plains and the source of its magnetic field for more than 30 yrs.Now,analyses of data from the Jan. 2008 flyby of the planet by MESSENGER Spacecraft have shown that volcanoes were involved in>>
Scientists are using the giant Robert C. Byrd Green Bank Telescope (GBT) to go prospecting in a rich molecular cloud in our Milky Way Galaxy.They seek to discover new,complex molecules in interstellar space that may be precursors to life.As molecules rota
A new star,likely the brightest supernova in recorded human history,lit up planet Earth's sky in the year 1006 AD.The expanding debris cloud from the stellar explosion,found in the southerly constellation of Lupus,still puts on a cosmic light show across
2 University of Iowa space physicists report that the Voyager 2 spacecraft,which has been traveling outward from the Sun for 31 years,has made the first direct observations of the solar wind termination shock.At the termination shock the solar wind,which
The jury is still out on whether hydrogen will ultimately be our environmental savior, replacing the fossil fuels responsible for global warming and pollution. The cost of producing fuel cells, and the lack of refueling network. Are major hurdles
A delicate ribbon of gas floats eerily in our galaxy.A jet from a black-hole?Actually this image is a very thin section of a supernova remnant caused by a stellar explosion that occurred more than 1,000 years ago.On or about May 1,1006 AD observers from

NASA's Cassini mission is closing one chapter of its journey at Saturn and embarking on a new one with a two-year mission that will address new questions and bring it closer to two of its most intriguing targets - Titan and Enceladus.On June 30,Cassini>>
Astronomers recently announced that they have found a novel explanation for a rare type of super-luminous stellar explosion that may have produced a new type of object known as a quark star.A quark star is a hypothetical type of star composed of ultra den
The centennial anniversary of the last big impact, the 1908 Tunguska blast that rocked Siberia, falls Monday, June 30, bringing with it a reminder of the very slight chance that a hunk of space rock out there might have Earth's number.
A clump of hair that lay frozen in the Greenland tundra for 4,000 years has yielded DNA from the earliest Arctic residents, and offers clues to their origins.
New analysis of Mars' terrain using NASA spacecraft observations reveals what appears to be by far the largest impact crater ever found in the solar system.NASA's Mars Reconnaissance Orbiter and Mars Global Surveyor have provided detailed information>>>>
