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...

NASA Warns Of Massive Solar Storm That Could Trigger Blackouts
The powerful X2.7-class solar flare erupted from a newly active sunspot, AR4087, and peaked on May 14.

NASA Satellite Captures Solar Eclipse Visible Only From Space
A solar eclipse visible only from space was captured in various images thanks to the US space agency NASA's Solar Dynamics Observatory (SDO).

Study Finds Coronal Loop Flickers Could Predict Solar Flares Hours in Advance
NASA's Solar Dynamics Observatory has revealed a potential breakthrough in predicting solar flares. Scientists observed brightness fluctuations in coronal loops—plasma structures in the Sun's atmosphere—that intensify hours before solar flares occur. This discovery, with a prediction accuracy of 60–80%, may provide 2–6 hours of advance warn...

NASA Might Have Spotted Highest Number of Sunspots in Over 20 Years
On August 8, 2024, NASA's Solar Dynamics Observatory (SDO) may have documented a record-breaking number of sunspots in a single day, marking a significant event in Solar Cycle 25. These sunspots, which are dark, cooler areas on the Sun’s surface caused by intense magnetic activity, play a crucial role in the Sun's behaviour and have a direct impa...

NASA Observatory Captures Image Of Aurora Created By A Solar Storm
The near-Earth Solar Dynamics Observatory captured this CME in September 2012, which traveled over 900 miles per second (1,448 kilometers per second), causing an aurora to appear.
