dust disk around black hole in NGC 4261 An accretion disk that might be producing planets around a young star named HD 141569A, in an image taken by the Hubble Space Telescope. The star lies some 320 light-years from Earth. The photograph has been modified to simulate what the disk would look like if viewed from above, and false colours were added to better show the disk's structure. To reveal the disk, the star's light was blocked out, so a black central region appears in place of the star. A nearby double-star system appears at upper left.
