Latest Bryan Gaensler Stories
A new home-grown instrument based on bundles of optical fibers is giving Australian astronomers the first 'Google street view' of the cosmos — incredibly detailed views of huge numbers of galaxies.
An observation of the Large Magellanic Cloud (LMC) in February of 1987 left astronomers thinking they had discovered the beginnings of a new star. However, what they had witnessed was the end of one of the brightest supernovae seen from Earth since the invention of the telescope some 400 years earlier.
Vital clues about the devastating ends to the lives of massive stars can be found by studying the aftermath of their explosions. In its more than twelve years of science operations, NASA's Chandra X-ray Observatory has studied many of these supernova remnants sprinkled across the Galaxy.
Like looking for Easter eggs in a lawn of long grass, the hunt for the Milky Way's most massive stars takes persistence and sharp eyes.
By Anonymous The voices of science were drowned out when 1000 of Australia's brightest minds discussed ideas for the nation's future. Six years ago this magazine launched conScience, an opinion column to give Australians an outlet "for expressing forthright views on national issues".
ESAâ€™s orbiting X-ray observatory XMM-Newton has re-discovered an ignored celestial gem. The object in question is one of the youngest and brightest supernova remnants in the Milky Way, the corpse of a star that exploded around 1000 years ago.
Scientists have detected a flash of light from across the Galaxy so powerful that it bounced off the Moon and lit up the Earth's upper atmosphere. The flash was brighter than anything ever detected from beyond our Solar System and lasted over a tenth of a second.
Astronomy is a science of extremes--the biggest, the hottest, and the most massive. Today, astrophysicist Bryan Gaensler (Harvard-Smithsonian Center for Astrophysics) and colleagues announced that they have linked two of astronomy's extremes, showing that some of the biggest stars in the cosmos become the strongest magnets when they die.
