The Cat’s Tail and the Fork MIRI F2300C deconvolved Image of a disk around a star. In the center is a black circle and lines, which are an instrumental artifact. The main disk is a thin, fuzzy yellow line. The "Fork" is a thin line below the disk that is at a slight angle. Text: "Extenstion of inclined inner disk. Also seen at shorter wavelengths, e.g. HST STIS, Apai et al. 2015." Above the disk is the "cat's tail" a curved line above the disk. Above this is an area of pink-ish clumps, labeled "Clumpy Nebulosity."

New observations of the debris desk around the star Beta Pictoris from Marshal Perrin. They see a new feature they are calling the "cat's tail" which may be dust being blow out of the system after a collision of two planetesimals.
