Most distant and ancient supernovae discovered by the Subaru Telescope. In the image, which show the Subaru Deep Field, numerous supernovae related to white dwarfs were found, and ten of them had exploded more than ten billion years ago. This discovery gives an important clue to study how the heavy elements created in the ancient universe (Graur et al.

متن کاملAstronomical archives of the future: a Virtual Observatory
Astronomy is entering a new era as multiple, large area, digital sky surveys are in production. The resulting datasets are truly remarkable in their own right; however, a revolutionary step arises in the aggregation of complimentary multi-wavelength surveys (i.e. the cross-identification of a billion sources). Federating these different datasets, however, is an extremely challenging task. With ...
متن کاملReport on Astronomical Constants
Recent progress in the determinations of astronomical constants is reviewed. First is the latest estimation of the general relativistic scale constants, LC , LG, and LB (Irwin and Fukushima, 1999). By reestimating the uncertainty, the value of the rst constant is given as LC = 1:480 826 867 4 10 8 1:4 10 . Also noted is the rigorous relation among these three, LB = LC +LG LCLG. Based on the lat...
