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.

                                2021 July 19
    [2]The picture shows part of the band of our Milky Way Galaxy as seen
    through a ring of trees. Please see the explanation for more detailed
                                information.

                   Framed by Trees: A Window to the Galaxy

   Explanation: The photographer had this shot in mind for some time. He
   knew that [4]objects overhead are the brightest -- since their light is
   [5]scattered the least by [6]atmospheric air. He also that knew the
   [7]core of our Milky Way Galaxy was just about straight up near
   midnight around this time of year in [8]South [9]Australia. Chasing his
   mental picture, he ventured deep inside the [10]Kuipto [11]Forest where
   tall [12]radiata pines blocked out much of the sky -- but not in this
   clearing. There, through a window framed by trees, he captured his
   envisioned combination of local and distant nature. Sixteen exposures
   of both trees and the [13]Milky Way Galaxy were recorded. [14]Antares
   is the bright orange star to left of [15]our Galaxy's central plane,
   while [16]Alpha Centauri is the bright star just to the right of the
   image center. The direction toward our [17]Galaxy's center is below
   Antares. Although in a few hours the [18]Earth's rotation moved the
   Galactic plane up and to the left -- soon [19]invisible behind the
   timber, his mental image was secured forever -- and is [20]featured
   here.
