Yohkoh Public Outreach Project

Welcome to the Yohkoh Movie Theater!

The Yohkoh Movie Theater (YPOP) is designed to bring you images and movies depicting our nearest star, the Sun, as seen by an X-ray telescope that was carried on board the Yohkoh satellite. The YPOP site includes a range of activities for youngsters, parents, teachers and anyone interested in learning more about the Sun. You can make your own movies, see solar images, take a tour of the Sun and much much more. This is a public domain site.

The Yohkoh satellite was an observatory for studying X-rays and gamma-rays from the Sun. Yohkoh was launched from Kagoshima, Japan on August 31, 1991, and was lost on December 14, 2001. In over ten years of observing the Sun (much longer than the proposed mission life) Yohkoh revolutionized our understanding of solar activity. Yohkoh is a project of the Institute for Space and Astronautical Sciences. The spacecraft was built in Japan and the observing instruments have contributions from the U.S. and from the U.K. The name Yohkoh is Japanese for "sunbeam".
