A new study, using the capabilities of the Subaru Telescope, has captured a clear image of the protoplanetary disk of the star UX Tau A.









 An international team of researchers from the National Astronomical Observatory of Japan (NAOJ) and the Japanese universities of Kobe, Hyogo, and Saitama released a detailed study of the disk’s characteristics, suggesting that its dust particles are large in size and non-spherical in shape. The results of this observation show that the dust particles are colliding with and adhering to each other. This process will eventually lead to the formation of planets. The findings of this study will be published in an upcoming issue of Publications of the Astronomical Observatory of Japan.
