What is the relationship between Stonehenge in Britain and astronomical phenomena?

There is a group of stones called Stonehenge in the north of Salisbury, England. The main body of Stonehenge is huge stone pillars, which stand upright on the plain and are arranged in a circle. Each stone pillar is 4m high, 2m wide, 1 m thick and weighs 25t. The two largest arched stone pillars weigh 50 tons. In the huge stone array, explorers found a circular group pit surrounded by 56 stone pillars, which was filled with human skulls, ashes, bone needles, flints and other daily necessities.

As early as more than 200 years ago, people noticed that on the summer solstice, the main axis of Stonehenge points in the direction of sunrise, and on the winter solstice, the connecting line of two stones points in the direction of sunset. British astronomers pointed out that the connection between the center of Stonehenge and a stone is related to astronomical phenomena. At Stonehenge, one piece points to the sunset on May 6th and August 8th, while the connecting line between the center and another stone points to the sunrise on February 5th and165438+1October 8th. Because these four days are roughly four solar terms: Long Summer, beginning of autumn, beginning of spring and beginning of winter, he thinks that the people who built Stonehenge have a calendar with eight solar terms a year.

In the early 1960s, astronomer Newham discovered signs pointing in the direction of the vernal equinox and the autumnal equinox sunrise. He also pointed out that four stones numbered 9 1, 92, 93 and 94 formed a rectangle, and their long sides pointed in the direction of the southernmost rising point and the northernmost falling point of the moon. Astronomer Hawkins found many new lines indicating the direction of the sun and the moon, so he thought that the 56 Aubrey caves at Stonehenge could predict the solar eclipse. Astronomer Doyle thinks Stonehenge can better predict solar eclipses.

However, many people suspect that Stonehenge is an ancient astronomical observatory, because these huge stones need to be transported to distant Welsh mountains and built by people with extremely strong labor force of10.5 million, which was an extremely difficult project at that time. In addition, the phenomenon of human bones in the circular pit cannot be explained clearly.
