Searching for First Stars in the Universe by Rocket Observations of the Cosmic Infrared Background Radiation

This research aims to detect the first-generation stars in the universe in one billion years later after Big-bang by measuring their lights as the cosmic infrared background radiation. As the result of our rocket-borne observations with a designated infrared telescope, we first succeeded to measure spectrum of the cosmic infrared background radiation in the visible-infrared wavelength range. This result would give a great impact to the research in the early universe and the first-generation stars.
