柔和的色調、部分照亮的星球、細微的環痕和輕微的陰影，突顯了巨型行星土星周圍的壯麗景色。這幅圖片由目前仍在繞行土星的機器人Cassini探測器拍攝，展示了土星的彎月相和它的衛星瑞亞（Rhea）。儘管上述圖片引人注目，但它只是一部60幀無聲影片中的一幅單幀，其中瑞亞可見地在其母星前方滑過。由於Cassini幾乎在土星環的平面上，因此通常壯觀的環在這幅圖片的中心僅以細線的形式可見。

Soft hues, partially lit orbs, a thin trace of the ring, and slight shadows highlight this understated view of the majestic surroundings of the giant planet Saturn. Looking nearly back toward the Sun, the robot Cassini spacecraft now orbiting Saturn captured crescent phases of Saturn and its moon Rhea in color a few years ago. As striking as the above image is, it is but a single frame from a 60-frame silent movie where Rhea can be seen gliding in front of its parent world. Since Cassini was nearly in the plane of Saturn’s rings, the normally impressive rings are visible here only as a thin line across the image center.
