Megalithic monuments are among the earliest and most permanent of archaeological structures, and so many of them were used, or more properly, have been used and reused for thousands of years. Their original intent is likely lost to the ages, but they may have had multiple functions as they were used by different cultural groups over the centuries and millennia.
Zodiacal signs are of equal length whereas the zodiacal constellations are not equal in length. Whether or not you believe horoscopes are worthwhile, it seems Ophiuchus won’t be disrupting our astrological zodiac any time soon.
The full moon known as this year’s Harvest Moon — a moon that appears bigger and brighter than usual due to its close proximity to earth — rises tonight coincided with a minor, penumbral lunar eclipse for many people in Asia and Africa. That won’t happen again until 2024.
Today, the summer solstice and full moon coincide — a rare event, indeed, that hasn’t happened in nearly 70 years, according to The Old Farmer’s Almanac. It’s a once-in-a-generation pairing: the start of astronomical summer and emergence of the full “Strawberry Moon.” June’s full Strawberry Moon got its name because the native American Algonquin tribes knew it as a signal to gather ripening strawberry fruit.
Today, the northern hemisphere is experiencing the shortest day of the year. The winter solstice marks the shortest daylight period, but it’s not the day of the latest sunrise or earliest sunset. In the mid-latitudes the earliest sunset occurs in early December, while the latest sunrise is not until early January.
The Jantar Mantar is an equinoctial sundial, consisting of a gigantic triangular gnomon with the hypotenuse parallel to the Earth’s axis. On either side of the gnomon is a quadrant of a circle, parallel to the plane of the equator. The instrument is intended to measure the time of day, correct to half a second and declination of the Sun and the other heavenly bodies.
Today is the winter solstice and the first day of winter in the Northern Hemisphere. It’s all due to Earth’s tilt, which ensures that the shortest day of every year falls around December 21. Some predicted that today would also mark Earth’s doomsday, thanks to a longstanding rumor that the Maya calendar ends on December 21, 2012.
