Planet of another star passing in front of its star

No. You cannot detect exoplanets in LegacySurvey images.


What’s happening here is that these stars are so bright that they saturate the CCD detectors, and then it gets flagged by the processing software and the colors may get messed up. If you flip over to the Legacy Surveys DR10 layer, you’ll see that the bright stars look a bit different because we handle saturation differently.

As spcgoat says, you can’t see planets in these images. With these cameras, all stars are tiny fractions of a pixel across; they only look extended because of blurring by the atmosphere.
