By adjusting the brightness and contrast of the photos, NASA shared a unique photo of the sun during Halloween. The footage is based on data captured by the Solar Dynamics Observatory (SDO), which allows us to know the active regions of stars that cannot be directly observed by the naked eye. Through a search and adjustment, the agency last week released this image of the sun in the shape of a pumpkin lamp.
More specifically, the image is rendered (usually golden) after overlaying data at two different wavelengths, 193 and 171 angstroms.
The darker areas in the graph indicate that the sun’s activity intensity is relatively weak. But the vortex of golden light is still trying to break through the dark area.
NASA notes that the active areas of the sun appear brighter than others. The energy and light it emits have a lot to do with the strong and complex magnetic field in the corona.
