Title: On the lambda Bootis spectroscopic binary hypothesis
Authors: Christian Stuetz, Ernst Paunzen
It is still a matter of debate if the group of lambda Bootis stars is homogeneously defined. A widely discussed working hypothesis formulates that two apparent solar abu...

VLT Interferometer detects disc around aged star A team of European astronomers has used ESO's Very Large Telescope Interferometer and its razor-sharp eyes to discover a reservoir of dust trapped in a disc that surrounds an elderly star. The discovery provides additional clues about the shaping...
When four-year old Alice Maines released her balloon at her school fete on a rainy day in Manchester, UK, never in her wildest dreams did she imagine that it would end up being found by Xie Yufei in a park in Guangzhou, a sprawling metropolis 75 miles north of Hong Kong. The balloon, that cost just one pou...

Title: HST search for M subdwarf binaries Authors: Basmah Riaz, John E. Gizis, Debasmita Samaddar We present HST/ACS observations of 19 nearby M subdwarfs in a search for binary systems. Other than the wide common proper motion pair LHS 2140/2139, none of our sdM and esdM targets are found to be bina...
High school students and teachers will join astronomers on the cutting edge of science under a program to be operated by the National Radio Astronomy Observatory (NRAO) and West Virginia University (WVU), and funded by the National Science Foundation (NSF). The program, called the Pulsar Search...
Using a tether system devised by MIT researchers, astronauts could one day stroll across the surface of small asteroids, collecting samples and otherwise exploring these rocks in space without floating away. The ability to visit asteroids could also be invaluable for testing equipment for a mis...
The National Optical Astronomy Observatory (NOAO) have conducted a study on the Large Magellanic Cloud and Small Magellanic Cloud, called the Magellanic Cloud Emission Line Survey (MCELS). And now you can see the imagery in Google sky. noao_showcase_n.kmz [url=http://www.box.net/shared/...
Title: An object that defies stereotypes. X-ray observations of SBS 1150+599A -- the binary nucleus of PN G135.9+55.9 Authors: G.Tovmassian, J.Tomsick, R.Napiwotzki, L.Yungelson, G.Stasiska, M.Peña, M.Richer We present X-ray observations of the close binary nucleus of the planetary nebul...

A boat that plied the coast of the Holy Land 1,300 years ago carrying fish, carobs and olives is helping researchers better understand a little-known period in the region's history. The boat, discovered in a coastal lagoon near the northern city of Haifa, dates from the early 8th century, not lo...
Scientists have shown how bacteria in space can gain virulence. When Salmonella typhimurium food bugs were flown in special flasks on the shuttle, they were found to alter the way they expressed 167 genes. The bacteria were almost three times as likely to kill infected mice compared with standard s...
