| Mysterious hot spots observed in cool red supergiant Posted: 24 Apr 2013 07:24 PM PDT Astronomers have released a new image of the outer atmosphere of Betelgeuse – one of the nearest red supergiants to Earth – revealing the detailed structure of the matter being thrown off the star. |
| Looking for life by the light of dying stars Posted: 24 Apr 2013 08:23 AM PDT Astronomers have now demonstrated that with the advanced technology available in the next decade we should be able to detect biomarkers like oxygen and methane in the planets that orbit dead stars called "white dwarfs" -- and to find new forms of life on those planets. |
| Posted: 23 Apr 2013 06:09 AM PDT A research team in Japan has performed deep imaging linear and circular polarimetry of the 'Cat's Paw Nebula' (NGC 6334) located in the constellation Scorpius, successfully detecting high degrees of circular polarization (CP) of as much as 22% in NGC 6334. The detected CP degree is the highest ever observed. |
