NASA’s Solar Observatory Sees Two Eclipses in One Day
In a rare celestial event, NASA’s Solar Dynamics Observatory (SDO) captured two eclipses on July 25, 2025. First, at 2:45 UTC, the Moon passed between SDO and the Sun, covering about 62% of the solar disk. Just hours later, around 6:30 UTC, Earth itself blocked the Sun entirely from SDO’s perspective. These dual eclipses occurred during SDO’s eclipse season and were observed in remarkable ultraviolet detail. The Moon’s silhouette appeared sharp, while Earth’s edge looked diffused due to atmospheric scattering. Since 2010, SDO has been a critical tool in observing solar phenomena and helping forecast space weather events.
