Image: NASA's SDO catches a lunar transit
From SDO's point of view, the sun appears to be shaking slightly – but not because the solar observatory was spooked by this near-Halloween sight.
Instead, the shaking results from slight adjustments in SDO's guidance system, which normally relies upon viewing the entire sun to center the images between exposures.
SDO captured these images in extreme ultraviolet light, a type of light invisible to human eyes. The imagery here is colorized in red.
