Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

                                2025 June 18
    [2]A detailed view of part of Earth's Moon is shown with many craters
     visible. On the lower right, silhouetted against the comparatively
     bright Moon, is a small dark silhouette of the International Space
      Station. Many of the solar panels on the station are discernable.
          Please see the explanation for more detailed information.

   Explanation: What's that unusual spot on the Moon? It's the
   [4]International Space Station. Using precise timing, the
   [5]Earth-orbiting space platform was photographed in front of a
   partially lit [6]gibbous Moon in 2019. The [7]featured image was taken
   from [8]Palo Alto, [9]California, [10]USA with an exposure time of only
   [11]1/667 of a second. In contrast, the duration of the transit of the
   [12]ISS across the entire Moon was about half a second. A [13]close
   inspection of this unusually [14]crisp ISS silhouette will reveal the
   outlines of numerous solar panels and trusses. The bright [15]crater
   Tycho is visible on the lower left, as well as comparatively rough,
   light colored terrain known as [16]highlands and relatively smooth,
   dark colored areas known as [17]maria. Downloadable [18]apps can tell
   you when the [19]International Space Station will be visible from your
   area.
