According to Chinese records from 687 BC, \"stars fell like rain\" from the sky at that time. In 1982, up to 90 meteors per hour were recorded. The origin of the April Lyrids can be attributed to comet C\/1861 G1 (Thatcher), which was discovered on April 4, 1861 by the British amateur astronomer A. E. Thatcher. Its orbital period is 416 years.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-2 wp-block-paragraph\"><strong>SUN AND MOON<\/strong><\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-3 wp-block-paragraph\">On the first of the month, the central star rises in Zweibr\u00fccken at 7:04 am and sets at 8:05 pm. The length of the day is 13 hours 1 minute and increases further to 14 hours 43 minutes at the end of the month. The full moon on 24.04. will affect the view of fainter objects and thus also the Lyrids (see above).<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"119\" src=\"https:\/\/sternwarte-zweibruecken.de\/wp-content\/uploads\/2024\/03\/VdS-Mondphasen_2024-04-1024x119-1.jpg\" alt=\"\" class=\"wp-image-2646\" style=\"width:728px;height:auto\" srcset=\"https:\/\/sternwarte-zweibruecken.de\/wp-content\/uploads\/2024\/03\/VdS-Mondphasen_2024-04-1024x119-1.jpg 1024w, https:\/\/sternwarte-zweibruecken.de\/wp-content\/uploads\/2024\/03\/VdS-Mondphasen_2024-04-1024x119-1-300x35.jpg 300w, https:\/\/sternwarte-zweibruecken.de\/wp-content\/uploads\/2024\/03\/VdS-Mondphasen_2024-04-1024x119-1-768x89.jpg 768w, https:\/\/sternwarte-zweibruecken.de\/wp-content\/uploads\/2024\/03\/VdS-Mondphasen_2024-04-1024x119-1-18x2.jpg 18w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Source: VDS, www.sternfreunde.de<\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-4 wp-block-paragraph\">On April 10 at 21:00, there will be an interesting view of the sky when the still young crescent moon appears to pay a visit to the large gas planet Jupiter just above the western horizon. At the time indicated above, the moon is approx. 3.3 degrees northwest of the planet.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-5 wp-block-paragraph\"><strong>PLANETS<\/strong><\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-6 wp-block-paragraph\">Almost all the convertible stars retire from the night sky during the course of the month. However, replacements are already near the starting holes.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-7 wp-block-paragraph\"><strong>Mercury<\/strong> has retreated to the daytime sky and can therefore no longer be observed.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-8 wp-block-paragraph\">The morning star that has been visible in recent months <strong>Venus<\/strong> has also retreated to the daytime sky. Our sister planet will not be visible in the evening sky again until August.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-9 wp-block-paragraph\"><strong>Mars <\/strong>will not appear in the morning sky again until the last third of May, as described in the overview for March.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-10 wp-block-paragraph\"><strong>Jupiter<\/strong> is still apparently approaching the sun. For telescope observers, it is no longer of great interest due to its apparently decreasing diameter and increasing distance from Earth. At the time of opposition in November 2023, its distance was 3.98 astronomical units (595 billion km) with a diameter of 49.5 arc seconds. On April 15, 2024, the distance is 5.90 AU (883 billion km) with a diameter of only 33.4 arc seconds. It will no longer be visible to the naked eye from the end of April.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-11 wp-block-paragraph\"><strong>Saturn <\/strong>can gradually assert itself against the sun towards the end of the month, late in the morning sky.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-12 wp-block-paragraph\"><strong>Uranus<\/strong> and <strong>Neptune<\/strong> move in the daytime sky and are therefore invisible to us.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-13 wp-block-paragraph\"><strong>STARRY SKY<\/strong><\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-14 wp-block-paragraph\">The spring constellations are now high in the sky. Only in the west are the remains of the winter constellations still visible.

In Greek mythology, Apollo, son of Zeus, once sent a raven with a cup to fetch water from a spring for an offering to his father. On the way, the raven was distracted by a fig tree whose fruit was not yet ripe. The black bird waited until the fruit was edible, ate it and only then completed his task. As an excuse for his delay, the raven bird grabbed a water snake and claimed that it had denied him access to the spring. Apollo saw through the lie and sent the raven, the cup and the water snake to heaven as a warning.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-16 wp-block-paragraph\">In the <strong>East<\/strong> another Greek hero, the summer constellation of Hercules, is already making his presence felt.
