- Two cosmic bursts upset tidy association between long gamma-ray bursts and supernovae
12-20-2006 · EurekAlert!
Only in the past decade have astronomers been able to make sense of the bright flashes of cosmic light known as gamma-ray bursts, which are the brightest explosions in the universe. But two newly observed bursts reported in this week's Nature suggest that not all can be neatly divided between long bursts associated with supernovae and short bursts due to stellar mergers.

- Space Weather Gear Readied For The Final Frontier
09-29-2006 · ScienceDaily
Atmospheric outflows, auroral emissions and plasma winds? While those aren't terms we hear on the average weather forecast, they cause cosmic storms that rage just outside the Earth's atmosphere and often wreak havoc with telecommunications networks, power grids and other technology essential to Canadian society. Researchers are hoping to gain a better understanding of this "space weather" with a suite of scientific instruments being developed under the leadership of the University of Calgary's Institute for Space Research.

- Researchers using Arecibo Telescope discover never-before-seen pulsar blasts in Crab Nebula
01-08-2007 · EurekAlert!
Astronomers and physicists using the Cornell-managed Arecibo Telescope in Puerto Rico have discovered radio interpulses from the Crab Nebula pulsar that feature never-before-seen radio emission spectra. This leads scientists to speculate this could be the first cosmic object with a third magnetic pole.

- 'Axis of evil' a cause for cosmic concern
04-11-2007 · EurekAlert!
The "axis of evil" (a mysterious pattern seen in the cosmic microwave background) may be real, posing a threat to the standard model of cosmology -- the idea that the universe is much the same everywhere. New data from the Sloan Digital Sky Survey suggests that the axes of rotation of most spiral galaxies appear to line up with the axis of evil.

- The frugal cosmic ant
09-27-2007 · EurekAlert!
Using ESO's Very Large Telescope Interferometer and its unique ability to see small details, astronomers have uncovered a flat, nearly edge-on disc of silicates in the heart of the magnificent Ant Nebula. The disc seems, however, too 'skinny' to explain how the nebula got its intriguing ant-like shape.

- Chandra discovers cosmic cannonball
11-28-2007 · EurekAlert!
One of the fastest moving stars ever seen has been discovered with NASA's Chandra X-ray Observatory. This cosmic cannonball is challenging theories to explain its blistering speed.Astronomers used Chandra to observe a neutron star, known as RX J0822-4300, over a period of about five years. During that span, three Chandra observations clearly show the neutron star moving away from the center of the Puppis A supernova remnant at over 3 million miles per hour.

- New experiment to investigate the effect of galactic cosmic rays on clouds and climate
10-23-2006 · EurekAlert!
A novel experiment, known as CLOUD (Cosmics Leaving OUtdoor Droplets), begins taking its first data today with a prototype detector in a particle beam at CERN , the world's largest laboratory for particle physics. The goal of the experiment is to investigate the possible influence of galactic cosmic rays on Earth's clouds and climate. This represents the first time a high energy physics accelerator has been used for atmospheric and climate science.

- Delft nano-detector very promising for remote cosmic realms
01-17-2007 · EurekAlert!
A miniscule but super-sensitive sensor can help solve the mysteries of outer space. Cosmic radiation, which contains the terahertz frequencies that the sensors detect, offers astronomers important new information about the birth of star systems and planets. Merlijn Hajenius developed these sensors for Delft University of Technology's Kavli Institute of Nanoscience, in cooperation with the SRON Netherlands Institute for Space Research. He will receive his PhD degree on 19 January based on this research subject.
