Subaru Approaches Origin of Comets
Subaru Approaches Origin of Comets
November 1, 2001
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.

Discovery of Seven New Distant Supernovae
Discovery of Seven New Distant Supernovae
July 12, 2001
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).

Subaru Discovers Small Objects in Outer Solar System
Subaru Discovers Small Objects in Outer Solar System
May 23, 2001
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'
April 30, 2001
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.
