NASA to Study Sun's Corona During Upcoming Solar Eclipse

NASA scientists are preparing to leverage the upcoming total solar eclipse for unprecedented research into the sun's corona, the star's outer atmosphere. This celestial event offers a unique window, allowing researchers to study the corona from Earth's surface in ways impossible from any other vantage point in the solar system. The sun's dynamic nature means each eclipse presents new phenomena, offering continuous learning opportunities.

The Sun is constantly changing. Every eclipse is different. So we can see phenomena that we haven't observed before. And every eclipse teaches us how to observe the next one even better.

"The Sun is constantly changing. Every eclipse is different. So we can see phenomena that we haven't observed before. And every eclipse teaches us how to observe the next one even better," Amir Caspi of the Southwest Research Institute stated, as quoted by NASA. Kelly Korreck, who leads the eclipse research program at NASA headquarters, emphasized the value of this terrestrial perspective for understanding the sun's influence on daily life, satellites, and astronauts.

To maximize observation time and capture data beyond the reach of ground-based telescopes, a high-altitude WB-57 aircraft will trail the moon's shadow. Equipped with high-resolution cameras, it will capture 20 images per second, documenting diverse phenomena within the corona. This flight will also record infrared wavelengths, which are typically absorbed by the lower atmosphere.

“

from the unique terrestrial perspective during a total solar eclipse, scientists can study the solar corona in a way that is not possible from anywhere else in the solar system.

The research aims to unravel mysteries surrounding solar protuberances, the mechanisms heating the corona to nearly a million degrees Celsius, and the intricate connection between coronal matter and the solar wind that permeates the solar system. Additionally, NASA-supported balloons from the Nationwide Eclipse Ballooning Project, managed by Montana State University, will be launched by students from the US, Iceland, and Spain to study the eclipse's impact on Earth's atmosphere.

The Sun affects our daily lives, satellites, and astronauts in space, and we can use this moment to better understand the nature of this interaction.
