The X-ray telescope on the Japanese Hinode spacecraft captured this series of shots, which have been rescaled and colored, showing the Moon blocking the Sun’s disk during the June eclipse. Astronomer Taro Sakao of the Japan Aerospace Exploration Agency (JAXA) took advantage of Hinode’s vantage point to observe how plasma moves within the high-speed solar wind stream, using the lunar silhouette for calibration of stray light.
