Observations
made with the High-Dispersion Spectrograph (HDS) of Subaru
Telescope have, for the first time, allowed astronomers
to measure the formation temperature of ammonia ice in a
comet. The temperature of 28 +/- 2 Kelvin (about -245oC
or -410oF) suggests that this comet, Comet LINEAR
(C/1999 S4), was formed between the orbits of Saturn and
Uranus. |

Presented
here is a new color image of the southwest region of the
Andromeda Galaxy taken with Subaru's prime focus camera
"Suprime-Cam". We see the stars of the Andromeda
Galaxy as a great many small white dots. Many of the stars,
star clusters, and nebulae in the image are seen clearly
resolved for the first time. |

Members of
the Subaru high-redshift supernova search group reported
on June 21st ( IAU
Circular No. 7649) the discovery of seven new supernovae.
All are very faint (at least 5 million times fainter than
the faintest stars visible to the unaided eye) and very
far away (at least a thousand times further than the nearest
large galaxy, M31 in the constellation of Andromeda). |

A Solar System
research team from the National Astronomical Observatory
of Japan (NAOJ), the Graduate University for Advanced Studies,
and the Science University of Tokyo have discovered small
objects extended within the outer solar system using Subaru
Telescope. Although more than 350 such objects are now known,
these are the first discovered by Japanese astronomers. |

Light From All the Galaxies in the Universe Accounted For Using the 'Subaru Deep Field'

A team of
astronomers from the National Astronomical Observatory of
Japan, the University of Tokyo, and Kyoto University has
completed a careful analysis of a very deep image taken
at near-infrared wavelengths. The "Subaru Deep Field"
(SDF) was observed soon after the first light of Subaru
Telescope, and subsequent study has revealed that the galaxies
detected in the image account for more than 90% of all the
galactic light in the Universe. |

Subaru Telescope
has successfully taken a sharp and deep infrared image of
the star-forming region, S106. In addition, many objects
with masses less than that of an ordinary star have been
discovered in this region. |
