Stonehenge - Astronomical Research

There has been a great deal of astronomical research conducted around Stonehenge over the years. Here are a few examples:

1. Solstice Alignment: One of the most well-known features of Stonehenge is its alignment with the solstices. The axis of the monument is aligned with the rising and setting of the sun on the summer and winter solstices. Astronomical research has focused on understanding the accuracy and significance of this alignment, as well as the techniques that the builders may have used to achieve it.

2. Lunar Standstill: In addition to the solstice alignment, Stonehenge is also believed to have been designed to mark the movements of the moon. Research has shown that the axis of the monument is aligned with the major and minor lunar standstills, which occur every 18.6 years. This suggests that the builders may have had a sophisticated understanding of lunar cycles and their relationship to the movements of the sun.

3. Sightlines: Stonehenge is not the only prehistoric monument in the area, and it is believed that the builders may have deliberately designed the site to be viewed in relation to other nearby features. Astronomical research has focused on identifying the various sightlines that exist between Stonehenge and other nearby monuments, as well as the possible significance of these alignments.

4. Stellar Alignments: While much of the focus on Stonehenge has been on solar and lunar alignments, there is also evidence to suggest that the monument may have been designed to mark the positions of stars. Astronomical research has focused on identifying the possible stellar alignments of the monument and understanding the significance of these alignments to the builders. Studies have shown that the Heel Stone, which stands outside the main circle, is aligned with the rising sun on the summer solstice. This suggests that the monument may have been used for astronomical observations and may have had a symbolic or religious significance related to the sun.
