Cosmic Giants Shed New Light on Dark Matter
June 12, 2013
An international team of astronomers has used the Subaru Telescope to measure the distribution of dark matter in fifty galaxy clusters and found that its density gradually decreases from the center of these cosmic giants to their diffuse outskirts. This new evidence about the mysterious dark matter that pervades our Universe conforms to the predictions of cold dark matter theory, known as "CDM"...
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 Sol 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...
