British astronomers say cosmic dust was partially created by the gradual death of carbon stars and not just from stars that exploded. The astronomers have been watching cosmic dust form around a dying star in a nearby galaxy, similar to the primitive galaxies that formed soon after the big bang, said a release from the Science and Technology Facilities Council, which funded the study. The newly observed dust formation was found around the carbon star MAG 29, located 280,000 light years away...

ITHACA, N.Y. "“ A Cornell-led team of astronomers has observed dust forming around a dying star in a nearby galaxy, giving a glimpse into the early universe and enlivening a debate about the origins of all cosmic dust. The findings are reported in the Jan. 16 issue of the journal Science (Vol. 323, No. 5912). Cornell research associate Greg Sloan led the study, which was based on observations with NASA's Spitzer Space Telescope. The researchers used Spitzer's Infrared Spectrograph,...

A team of University of Hertfordshire astronomers led by Dr David Pinfield of the Centre for Astrophysics Research is leading a major new European collaboration to search for and study planets around other stars (extra-solar planets). Funded with £2.75 million from the European Commission, this research and technology network will focus on the search for rocky planets around cool stars and the development of future space-based technology to study extra-solar planets. Cool stars are much...

A mysterious extra-loud radio noise permeates the universe, preventing astronomers from observing heat from the first stars, U.S. scientists at NASA said. The noise, picked up by a balloon-borne instrument, makes no sense, based on science's current understanding of the cosmos, the scientists at the National Aeronautics and Space Administration said. The universe really threw us a curve, said astrophysicist Alan Kogut of NASA's Goddard Space Flight Center in Greenbelt, Md. Instead of the...

Listening to the early universe just got harder. A team led by Alan Kogut of NASA's Goddard Space Flight Center in Greenbelt, Md., today announced the discovery of cosmic radio noise that booms six times louder than expected. The finding comes from a balloon-borne instrument named ARCADE, which stands for the Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission. In July 2006, the instrument launched from NASA's Columbia Scientific Balloon Facility in Palestine, Texas, and...

GREENBELT, Md., Jan. 6 /PRNewswire-USNewswire/ -- An ongoing X-ray survey undertaken by NASA's Swift spacecraft is revealing differences between nearby active galaxies and those located about halfway across the universe. Understanding these differences will help clarify the relationship between a galaxy and its central black hole.

WASHINGTON, Dec. 16 /PRNewswire-USNewswire/ -- For the first time, astronomers have clearly seen the effects of "dark energy" on the most massive collapsed objects in the universe using NASA's Chandra X-ray Observatory. By tracking how dark energy has stifled the growth of galaxy clusters and combining this with previous studies, scientists have obtained the best clues yet about what dark energy is and what the destiny of the universe could be. (Logo:...

Something vital is missing in the far distant reaches of the Universe: hydrogen - the raw material for stars, planets and possible life. The discovery of its apparent absence from distant galaxies by a team of Australian astronomers is puzzling because hydrogen gas is the most common constituent of normal matter in the Universe. If anything, hydrogen was expected to be more abundant so early in the life of the Universe because it had not yet been consumed by the formation of all the stars and...

Scientists believe they may now have a better idea of where to search for dark matter thanks to the results of a giant computer simulation reported on Wednesday. Dark matter has puzzled scientists for about 75 years when they discovered its existence from its gravitational effects. The mysterious matter is considered to account for 85 percent of the universe's mass although it cannot be seen through telescopes. Researchers at the international Virgo Consortium, including cosmologists at...

Gamma-ray bursts are by far the brightest and most powerful explosions in the Universe, second only to the Big Bang itself. So it might seem a bit surprising that a group of them has gone missing. A single gamma-ray burst (GRB) can easily outshine an entire galaxy containing hundreds of billions of stars. Powerful telescopes can see them from clear across the Universe. And because the deeper you look into space, the farther back in time you see, astronomers should be able to see GRBs from the...

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

Xenobiology -- Xenobiology (or exobiology, or astrobiology) is the term for a speculative field within biology which considers the possibility of, and possible nature of, extraterrestrial life. It also necessarily includes the concept of artificial life, since any life form might naturally evolve elsewhere, could conceivably come out of a laboratory using a future technology. It might be difficult to tell whether a truly strange life form had in fact arisen in space, or was designed much...
