New Horizons exploration target 2014 MU69 occults a star
Go here for information about the specific star that was occulted.
The original animation as posted on NASA's website was about 6 MB in size, and most of the variation in the image is attributable to noise. It was processed by performing a Gaussian blur with a 1-pixel radius in order to deemphasize the noise, and then resized slightly smaller with a bilinear interpolation to spread out the pixel-to-pixel variation a bit more. The original animation was also not aligned on the star field; this version has aligned the stars.
