133 Days on the Sun

Witness the captivating journey of solar activity spanning from August 12 to December 22, 2022, meticulously documented by NASA's Solar Dynamics Observatory (SDO). For over a decade, SDO has been our vigilant observer, unveiling the Sun's mysteries in astonishing 4K x 4K resolution.Show more

Through its advanced instruments, SDO unveils the Sun's dynamic nature with astonishing precision. Experience the breathtaking solar dance as SDO's Atmospheric Imaging Assembly (AIA) instrument captures intricate images every 12 seconds across 10 distinct wavelengths of light. This remarkable 133-day time-lapse showcases the Sun's ethereal corona at an extreme-ultraviolet wavelength of 17.1 nanometers, revealing its outermost atmospheric layer.

Watch in awe as 133 days of solar evolution are condensed into a 59-minute visual spectacle. Witness the Sun's radiant active regions traversing its surface during its approximately 27-day rotation period. Enigmatic loops extending above these luminous areas are magnetic fields imprisoning scorching plasma, while dazzling solar flares burst forth in a dazzling display of magnetic reconnection.

Marvel at the Sun's ballet, occasionally interrupted by fleeting moments of darkness caused by Earth or the Moon eclipsing SDO. These intriguing blackouts, along with the Sun's off-center appearances, offer a glimpse into SDO's calibration and the sheer magnitude of its 1.4 terabytes of daily transmitted data.

As SDO perpetually gazes upon our nearest star, it unveils cosmic secrets that shape our understanding of the universe. Join us in this celestial journey, as SDO and its fellow NASA missions continue to unveil the Sun's enigma, providing crucial insights for space exploration and ensuring the safety of our astronauts and invaluable assets.
