Scientists have discovered a large volcano off the southwestern coast of Iceland, and they think that it may erupt at any time. The find is significant because scientists had previously thought that volcanoes could not form in that area of the ocean. Such large volcanoes are not located on oceani...
Title: Strong magnetic spiral pattern in a ringed galaxy NGC4736 Authors: Krzysztof T. Chyzy (Jagiell. Univ.), Ronald J. Buta (Univ. of Alabama) We present high sensitivity radio polarimetric (VLA) observations of a galaxy with strong orbital resonances - NGC4736. The total radio intensity at...
Title: Where are the massive stars of the bar of NGC 1530 forming? Authors: A. Zurita (U. Granada), I. Perez (U. Groningen & U. Granada) Aims: NGC 1530 has one of the strongest bars ever observed and recent star formation sites are distributed across its bar. Our aim is to study the photometric pro...
Scientists in Finland have discovered a 780-year-old sylvester pine tree, the oldest living specimen known in Scandinavia, a research institute said on Tuesday. The ancient "pinus sylvestris", a contemporary of eighth-century emperor Charlemagne, was found last year in Lapland d...
Osmium isotopes in seawater sediment can be used to reveal ancient meteorite strikes, US-based scientists say. The sensitive technique could provide more details on the size of extraterrestrial rocks which have plunged into the sea and vaporised, leaving no crater-shaped calling card behind....
The Japan Aerospace Exploration Agency will examine its 16 operational satellites after a spate of minor mechanical glitches in the lunar orbiter Kaguya and other satellites in recent months. It will be the first such inspection of all domestic satellites in service. JAXA hopes the checks will id...
Title: The qWR star HD 45166. II. Fundamental stellar parameters and evidence of a latitude-dependent wind Authors: J. H. Groh (1,2), A. S. Oliveira (3,4), J. E. Steiner (2) ((1) MPIfR-Bonn/Germany, (2) IAG-USP/Brazil, (3) IP&D-Univap/Brazil, (4) SOAR Telescope/Chile) The enigmatic ob...
The University of Colorado at Boulder's own version of "The Rocket Boys" (and Girls) will help to launch a CU payload on a sounding rocket to measure ultraviolet radiation from the sun from the White Sands Missile Range in New Mexico April 10. [url=http://www.colorado.edu/news/r/daf...
An international team of astronomers has discovered the coldest brown dwarf star ever observed. This finding, to be published in Astronomy & Astrophysics, is a new step toward filling the gap between stars and planets. An international team led by French and Canadian astronomers has just di...
Title: OGLE-2005-BLG-071Lb, the Most Massive M-Dwarf Planetary Companion? Authors: Subo Dong, Andrew Gould, Andrzej Udalski, Jay Anderson, G.W. Christie, B.S. Gaudi, M. Jaroszynski, M. Kubiak, M.K. Szymanski, G. Pietrzynski, I. Soszynski, O. Szewczyk, K. Ulaczyk, L. Wyrzykowski, D.L. DeP...
Physicists have turned on the world's most powerful laser, whose pulses are more intense than any known light source in the universe. The incredible temperatures and pressures it generates when it hits a target will let scientists explore conditions found in exploding stars and the cores of giant...
This image of the Lake Janisjarvi Impact Crater was captured by the Landsat-7 satellite on September 5, 1999 . Lake Jänisjärvi is a 13 by 17 kilometres oval-shaped lake, in northwestern Russia, near the Finnish border. The crater was formed roughly 700 million years ago by a meteorite impact. Credi...
A research team investigated a disk of gas and dust surrounding a young star, as well as the stellar winds which emanate from that star. The team found unique, previously unknown characteristics of the innermost environment around the star. Another research group carried out the first-ever analy...
