At the height of the eclipse, the moon covers 67 percent of the sun
REPUBLIKA.CO.ID, JAKARTA — The Solar Dynamics Observatory (SDO) satellite belonging to the American Space Agency (NASA) captured solar eclipse from his unique point of view in outer space. In the published image, at the height of the eclipse, the moon covered 67 percent of the sun, and the lunar mountains were illuminated by solar fire.
Reported from SpaceThursday (30/6/2022) the mountains of the moon are backgrounded by the sun during a solar eclipse, Wednesday (29/6/2022) imaged by SDO NASA.
SDO typically views the sun as a source of space weather, or radiation in outer space that affects Earth. Aspects he studies include the sun’s magnetic field, sunspots and other aspects that affect activity during the sun’s 11-year regular cycle.
“SDO studies how solar activity is created and drives space weather. Measurements of the sun’s interior, atmosphere, magnetic field, and energy output by spacecraft work to help us understand the stars we live in,” NASA wrote from the mission.
SDO was launched in February 2010 and is part of the solar spacecraft network of NASA and its partner agency, the National Oceanic and Atmospheric Administration (NOAA). The sun has been quite active lately and is unusually early in its cycle, which should peak around 2025.
Scientists are interested in studying the origin of solar flares and the coronal mass ejection (CME) that accompanies charged particles. CMEs can create colorful auroras in Earth’s atmosphere if they are pointed at our planet.
Usually CMEs are harmless, but powerful explosions can disrupt satellites, power lines and other infrastructure, which is why scientists are so interested in good predictions.
