Subaru Telescope Observations and the CoRoT Mission Unveil the Future of the Sun
May 17, 2013
A team of astronomers has found the farthest known solar twin in the Milky Way Galaxy-- CoRoT Sol 1, which has about the same mass and chemical composition as the Sun. Spectra from the High Dispersion Spectrograph (HDS) on the Subaru Telescope showed that CoRoT Sun 1 is about 6.7 billion years old while space-derived data from the CoRoT satellite indicated a rotation period of 29 +/- 5 days. This newly discovered, evolved solar twin allows astronomers to uncover the near future of the Sun...
Discovery of a Blue Supergiant Star Born in the Wild
April 10, 2013
A duo of astronomers has discovered a blue supergiant star located far beyond our Milky Way Galaxy in the constellation Virgo. Over fifty-five million years ago, the star emerged in an extremely wild environment: within the long trail of gas stripped from galaxy IC 3418 as it sped rapidly into the Virgo cluster and interacted with the hot plasma of the surrounding intra-cluster medium. The research revealed unprecedented views of the star formation process in this intergalactic context and showed the promise of future investigations of a possibly new mode of star formation, unlike that within our Milky Way...
