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.

                              2024 September 9
      [2]A panoramic view of the surface of Mars. Several landforms are
   visible including craters and volcanos. A small dark moon is superposed
    in front of part of the surface. Please see the explanation for more
                            detailed information.

   Explanation: If you could fly over Mars, what might you see? The
   [11]featured image shows exactly this in the form of a [12]Mars Express
   vista captured over a particularly interesting region on [13]Mars in
   July. The picture's most famous feature is [14]Olympus Mons, the
   largest volcano in the [15]Solar System, visible on the upper right.
   Another large Martian volcano is visible on the right horizon:
   [16]Pavonis Mons. Several [17]circular impact craters can be seen on
   the surface of the aptly named [18]red planet. Impressively, this image
   was timed to capture the [19]dark and [20]doomed Martian moon
   [21]Phobos, visible just left of center. The [22]surface feature on the
   lower left, known as [23]Orcus Patera, is unusual for its large size
   and oblong shape, and [24]mysterious because the processes that created
   it still remain unknown. [25]ESA's robotic [26]Mars Express spacecraft
   was launched in 2003 and, among many [27]notable science
   [28]discoveries, bolstered evidence that Mars was once home to large
   [29]bodies of water.
