Infrared Astronomy Group
Unveiling the evolution of material in the Universe

Welcome to Space Astronomy Laboratory, Infrared Group (Uir)

Infrared light is electromagnetic radiation in the wavelength range from one to a few hundreds of microns. Our laboratory develops astronomical instruments and performs observations in infrared with space satellites, balloons, and ground-based telescopes.

Small solid particles, called dust grains, exist in the Universe. They play a crucial role such as in production of organic material indispensable for life, formation of rocky planets like the Earth, and evolution of galaxies. We aim to understand how the present-day universe has been shaped and chemically enriched through observations of dust grains, their production and evolution.


Four members joined the balloon experiment in India. The flight and observations were successfully done!
The sign of a planet was found in a young protoplanetary disk in Orion (NAOJ page).
Seven members presented the research results in the AKARI international conference.
IRSF catches the light from the source of gravitational wave! Please see the news page (NAOJ) for details.
New posdoc joined our lab., and the member list is updated.
The technological breakthrough has been achieved in developing new infrared detectors (TES), which will be on board the next generation space satellite, SPICA. Please visit the page in SRON for details.
