On selected dates throughout the year, they open their garden gates to give visitors a glimpse into their private green paradises. Such an \"open garden gate\" is also a good opportunity to present the most important factor for greenery and bloom \u2013 our sun!<\/p>\n\n\n\n<p><br><\/p>\n\n\n\n<p>On July 2, 2023, we opened our garden in Osnabr\u00fcck at the Sonnenh\u00fcgel from 11 a.m. to 6 p.m. for all interested parties. Anyone who was interested could come and have a look. More than 70 visitors did not miss the chance to take a \"look behind the scenes\" of our single-family home.<\/p>\n\n\n\n<p><br><\/p>\n\n\n\n<p>Some knew it in advance, but many were surprised to find an astronomical telescope set up to observe the sun. Although there were many clouds in the sky, the numerous gaps allowed a view to our home star sufficiently often. Most of the visitors wanted to look through the telescope and were impressed by the sight of the sun with its many spots (we are close to the solar activity maximum).<\/p>\n\n\n\n<p><br><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/kosmos-os.de\/wp-content\/uploads\/2023\/07\/IMG_7390-1024x683.jpg\" alt=\"\" class=\"wp-image-1806\" srcset=\"https:\/\/kosmos-os.de\/wp-content\/uploads\/2023\/07\/IMG_7390-1024x683.jpg 1024w, https:\/\/kosmos-os.de\/wp-content\/uploads\/2023\/07\/IMG_7390-300x200.jpg 300w, https:\/\/kosmos-os.de\/wp-content\/uploads\/2023\/07\/IMG_7390-768x512.jpg 768w, https:\/\/kosmos-os.de\/wp-content\/uploads\/2023\/07\/IMG_7390-1536x1024.jpg 1536w, https:\/\/kosmos-os.de\/wp-content\/uploads\/2023\/07\/IMG_7390-2048x1365.jpg 2048w, https:\/\/kosmos-os.de\/wp-content\/uploads\/2023\/07\/IMG_7390-500x333.jpg 500w, https:\/\/kosmos-os.de\/wp-content\/uploads\/2023\/07\/IMG_7390-800x533.jpg 800w, https:\/\/kosmos-os.de\/wp-content\/uploads\/2023\/07\/IMG_7390-1280x853.jpg 1280w, https:\/\/kosmos-os.de\/wp-content\/uploads\/2023\/07\/IMG_7390-1920x1280.jpg 1920w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><em>The sun often made it through the clouds.
