NASA satellite sees a partial solar eclipse from space Thursday

On May 25, NASA’s SDO satellite witnessed a partial solar eclipse in the space as it saw moon moving across the sun and blocking some of its light.The event lasted almost an hour and moon covered 89 percent of the sun at the peak of its journey.

The images taken by SDO looks so amazing because the sun, moon and the satellite were almost perfectly aligned.They reveal solar activity or atmosphere of the sun in a remarkable detail.

“While the moon’s edge appears smooth in these images, it’s actually quite uneven. The surface of the moon is rugged, sprinkled with craters, valleys and mountains. Peer closely at the image, and you may notice the subtle, bumpy outline of these topographical features.” NASA statement reads.

SDO or Solar Dynamics Observatory was launched in 2010 and has been constantly monitoring the sun ever since. The satellite studies Sun’s magnetic field, its formation and other solar activity at smallest scales and in different wavelengths simultaneously. The information then enables researchers understand the impact of Sun’s atmosphere, solar flares and high-energy particles on Earth and near-Earth space and also helps them find ways to protect the planet from the potential damaging effects.

SDO will observe another solar eclipse later this summer on August 21. It will look like just another partial solar eclipse if seen from space. But on the same day, a total solar eclipse will be observed from Earth. The moon will completely cover the sun and block the sunlight, casting a shadow on the Earth. The eclipse will darken the sky from Oregon to South Carolina for almost an hour and a half. It will be the first solar eclipse to cross US in 99 years and will look like someone just turned off the sun in the middle of the day.

When moon passes in front of the sun, it casts two types of shadows. The umbral is the small shadow which will be casted in the areas of total solar eclipse. Other regions, in this case parts of South America, Africa, Europe and Asia will experience the penumbral shadow because a partial eclipse will be visible there.
