Astronomy News and Research - March 2009 Archives
Scientists from the University of Sheffield and Queen's University Belfast have made a unique discovery which will help us understand one of the most puzzling features of the sun. The research has helped explain why the outside atmosphere of the sun is actually hotter than the inner photosphere.

 | New results from NASA's Chandra X-ray Observatory have made a major advance in explaining how a special class of black holes may shut off the high-speed jets they produce. These results suggest that these black holes have a mechanism for regulating the rate at which they grow. ...> Full Article |
 | A Purdue University aerospace researcher helped shape plans to install a new experiment currently on the space shuttle Discovery to collect data for controlling deadly friction and heating in the design of future spacecraft. ...> Full Article |

 | Does a twin Earth exist somewhere in our galaxy? Astronomers are getting closer and closer to finding an Earth-sized planet in an Earth-like orbit. NASA's Kepler spacecraft just launched to find such worlds. Once the search succeeds, the next questions driving research will be: Is that planet habitable? Does it have an Earth-like atmosphere? Answering those questions will not be easy. ...> Full Article |
Scientists at Queen's University have made a finding that will help us to understand more about the turbulent solar weather and its affect on our planet. Along with scientists at the University of Sheffield and California State University, the researchers have detected giant twisting waves in the lower atmosphere of the Sun.

 | Where do supernovae come from? Astronomers have long believed they were exploding stars, but by analyzing a series of images, researchers from the Dark Cosmology Center at the Niels Bohr Institute, University of Copenhagen and from Queens University, Belfast have proven that two dying red supergiant stars produced supernovae. The results are published in the prestigious scientific journal, Science. ...> Full Article |
 | An international team of astrophysicists using telescopes on the ground and in space have uncovered surprising changes in radiation emitted by an active galaxy. The picture that emerges from these first-ever simultaneous observations with optical, X-ray and new-generation gamma-ray telescopes is much more complex than scientists expected and challenges current theories of how the radiation is generated. ...> Full Article |

 | The ESO Very Large Telescope has taken the best image ever of a strange and chaotic duo of interwoven galaxies. The images also contain some surprises -- interlopers both far and near. ...> Full Article |
 | The NASA/ESA Hubble Space Telescope has uncovered a strong new line of evidence that galaxies are embedded in halos of dark matter. ...> Full Article |

 | Astronomers have obtained exceptional 3-D views of distant galaxies, seen when the Universe was half its current age, by combining the twin strengths of the NASA/ESA Hubble Space Telescope's acute eye, and the capacity of ESO's Very Large Telescope to probe the motions of gas in tiny objects. By looking at this unique "history book" of our Universe, scientists hope to solve the puzzle of how galaxies formed in the remote past. ...> Full Article |
The search for habitable planets continues with the March 6 launch of the Kepler spacecraft, the latest in NASA's series of low cost, highly focused Discovery missions. Kepler, built by Ball Aerospace & Technologies Corp., includes redundant avionics systems designed and built by Southwest Research Institute to help guide and control the spacecraft as it stares deep into space, watching for planets orbiting stars.

 | Using ESO's Very Large Telescope, astronomers have gained valuable new insights about the atmosphere of the dwarf planet Pluto. The scientists found unexpectedly large amounts of methane in the atmosphere, and also discovered that the atmosphere is hotter than the surface by about 40 degrees, although it still only reaches a frigid minus 180 degrees Celsius. These properties of Pluto's atmosphere may be due to the presence of pure methane patches or of a methane-rich layer covering the dwarf planet's surface. ...> Full Article |
 | Brown planetary geologists have located a gully system that appears to have been carved by melt water that originated in nearby snow and ice deposits. The gullies, which the team determined to be about 1.25 million years old, may represent the most recent period when water flowed on the planet. The findings appear on the cover of the March issue of Geology. ...> Full Article |
UK astronomers, using a telescope aboard the NASA Swift Satellite, have captured information from the early stages of a gamma ray burst -- the most violent and luminous explosions occurring in the Universe since the Big Bang.
