Research history and constellation myths and legends of rhododendrons

The research history and constellation myths and legends of Rhododendron are as follows: Rhododendron is a tiny constellation in the south, which means Toucan, and only China people misinterpret it as Rhododendron. Southern constellation, near the bright Star Water Committee I of the constellation Bojiang, is to the south of two other birds, cranes and phoenix in the sky. Historical research Rhododendron is a small constellation in the south, which means Toucan. Only people in China misunderstand it as azalea. Southern constellation, near the bright Star Water Committee I of the constellation Bojiang, is to the south of two other birds, cranes and phoenix in the sky. From 1595 to 1597, it was named by Dutch navigators PieterDirkszoonKeyser and Hortmann. In 1603, it was included in the "Sky Survey" by John Baer. Small magellanic cloud is one of the closest extragalactic galaxies to us, and it is located near the boundary between Rhododendron and Aquarius. 1519 ~1521year, when the Portuguese navigator Magellan sailed around the world south of the equator, he found two cloud-like celestial bodies in the southern sky. Magellan made a vivid description for the first time and announced the discovery after he returned to Europe. Later, in order to commemorate this outstanding navigator, people collectively called them Magellan clouds. Before that, they were called Cape of Good Hope clouds. Small magellanic cloud is a companion galaxy of our Milky Way. Its actual span is about 15000 light years, including hundreds of millions of stars. The small Magellanic Cloud is 654.38+09 million light years away, and its mass is about 654.38+0/654.38+000 of that of the Milky Way. Together with the Milky Way and the Large and Small Magellanic Clouds, it forms a triple galaxy. Near large magellanic cloud, there is also a globular cluster ξ (or 47)(NGC 104), with four stars brighter than four. The center of the azalea crosses the sky on the night of September 17 every year. Complete rhododendrons can be seen in the vast area south of north latitude 14 degrees, but this constellation can not be seen at all in the area north of 33 degrees north latitude. Rhododendron is the earliest constellation created by Dutch navigator P.D. Kaiser. This is a bird that lives in South America. It has a huge mouth and gorgeous feathers. 1603, German astronomer Bayer adopted this constellation in his star map. From 20 15 to 10, a team of astronomers led by Dr. Jeremy Hale of Columbia University observed the migration of about 3,000 white dwarfs with Hubble telescope. These white dwarfs are located in Rhododendron 47, a globular cluster in Southern Rhododendron, about 16700 light-years away from the Earth. In the observation of cuckoo 47 globular cluster, scientists have determined that several millisecond pulsars are accompanied by white dwarfs, and pulsars can accumulate matter from white dwarfs. When a star whose mass is about 10 times that of the sun ends its life, a spectacular supernova explosion can occur, and its remains are neutron stars. Neutron stars are only several times the mass of the sun, but they are also very small, with a diameter of only tens of kilometers. The neutron star is in a state of rapid rotation, emitting a lighthouse-like beam, which repeats a cycle every few seconds. This neutron star is also called a pulsar. Zeus, the mythical god of constellation, fell in love with Hera. Once, he saw Hera walking in the forest. It rained heavily immediately, and I became a cuckoo, pretending to hide from the rain, hiding in Hera's skirt, then showing my true colors and hugging Hera, vowing that unless Hera didn't marry. Rhododendron is the incarnation of Zeus and becomes a constellation in the sky.
