Ancient megaliths of Hazaribagh

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.

Chandrasekhar | He knew how the stars will die

Chandrasekhar became famous for his discoveries about the evolution of the stars. His work was vast, and he began early, developing his theory of stars’ evolution before he had even turned 20. Google is changing its logo globally to a doodle of him and the Chandrasekhar Limit. That refers to his calculation that once a star reaches 1.44 times the size of our own sun, it doesn’t form a white dwarf as expected but collapses, eventually becoming a black hole.

Solstice and Strawberry Moon tonight

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…

Makar Sankranti is not Uttarayana

Makar Sankranti is about nature, energy of the sun, harvest of new crop, and progress of mankind. It marks the end of Malmaas, an inauspicious month in the Hindu (Panchang) calendar, and the transition of the Sun to the zodiacal sign of Makar (Capricorn) to herald a change in season.

Winter solstice

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.
