Summer Solstice Spurs Global Festivities and Stargazing

The summer solstice marks the official start of astronomical summer in the Northern Hemisphere, resulting in the longest day of the year due to Earth's 23.5-degree axial tilt caused by an ancient planetary collision. This phenomenon leads to varying daylight hours, with regions near the North Pole experiencing the midnight sun and areas near the equator seeing only minimal daylight increase. The solstice continues to inspire a mix of ancient and modern celebrations, including music marathons like Chicago's 93XRT and community events such as Del Mar's sustainability-focused festival. Astronomical events, such as close conjunctions of Venus, Saturn, and the crescent moon, can also be observed around this time. The day highlights cultural traditions and scientific interest, reflecting its enduring significance across different regions. Modern festivities often honor both the natural phenomenon and local culture.
