Good morning and happy Saturday everyone! Did you know today, October 12, is International Astronomy Day? Astronomy is the study of everything in the universe beyond Earth’s atmosphere, from planets and stars to galaxies and the cosmic phenomena that fill space. It helps us understand the vastness of the universe and our place within it. Here are 5 fun facts about astronomy: 🌠 The Milky Way is huge – It’s about 100,000 light-years wide, and there are over 100 billion stars in it! 🔭 Ancient civilizations were astronomers – Cultures like the Egyptians and Mayans used the stars to navigate and create calendars. 🌍 Earth isn't perfectly round – Due to its rotation, it's slightly flattened at the poles and bulging at the equator. ☀️ Our sun is a star – It’s a giant ball of hot gases that supports all life on Earth. 🌒 You can see galaxies with the naked eye – On a clear night, the Andromeda Galaxy is visible from Earth, even though it’s 2.5 million light-years away! Happy International Astronomy Day! 🌌✨ #InternationalAstronomyDay #AstronomyDay #Astronomy #Stars #Planets #HRProfessional #TalentAcquisition #Recruiter

*The Surya Siddhanta is the name of a Sanskrit treatise in Indian astronomy from the late 4th-century or early 5th-century CE. The book was written by Aryabhatta. It's originally from 12000 BCE*   The *Surya Siddhanta*, an ancient Indian treatise on astronomy, is a foundational text in the field of Hindu astronomy. Its content demonstrates remarkable knowledge of celestial mechanics, distances, and sizes of celestial bodies, as well as sophisticated calculations of time, eclipses, and planetary orbits. The text is traditionally attributed to divine revelation by the Sun God, Surya, to Maya, the Asura, reflecting its deep cultural and spiritual significance. Below is an exploration of its astronomical concepts, its alignment with modern calculations, and the controversies surrounding its dating. *Key Celestial Concepts in the Surya Siddhanta* 1. *Celestial Bodies and Their Characteristics*:    - *Sun (Surya)*: Detailed as the central celestial body influencing planetary orbits.    - *Moon (Chandra)*: Its distance from the Earth is estimated with surprising accuracy, close to the modern average of ~384,400 km.    - *Planets*: Lists Mercury, Venus, Mars, Jupiter, and Saturn, with their periods of revolution.    - *Stars and Nakshatras*: Mentions 27 lunar constellations and their influence on Indian calendrical systems. 2. *Distances and Ratios*:    - The text mentions astronomical units that approximate modern calculations when converted, such as the Earth-Moon and Earth-Sun distances.    - The ratio of 108: The diameter of the Sun and Moon is approximately 108 times their respective distances from the Earth. This auspicious number appears repeatedly in Vedic and Hindu traditions. 3. *Advanced Concepts*:    - *Obliquity of the Earth*: Records an Earth tilt of 24°, close to the current 23.5°.    - *Time Dilation and Brahma’s Day*: Discusses vast timescales, including *kalpas* (4.32 billion years), aligning with modern geological and cosmological estimates of time.    - *Time Travel and Relativity*: Although not explicitly discussing Einstein’s theories, it hints at profound concepts of time dilation and cyclical time. 4. *Cosmology*:    - Suggests a geocentric model but uses it effectively to predict eclipses and planetary movements.    - Mentions the *Milky Way* as *Akasha Ganga*, but does not explicitly describe galaxies or black holes. 5. *Planetary Alignments*:    *Concluding Thoughts* The *Surya Siddhanta* stands as a testament to the intellectual achievements of ancient Indian civilization. Its insights into astronomy, time, and the cosmos demonstrate a sophisticated understanding that rivals modern calculations. While its exact dating and origins remain debated, it underscores the rich scientific heritage of India and its influence on global knowledge systems. Whether or not 16th–17th century astronomers drew directly from it, the *Surya Siddhanta* undeniably laid the groundwork for humanity’s exploration of the universe.

Today, 18-May-2024 is International Astronomy Day. This day is celebrated to promote and celebrate the significance of astronomy. One fascinating fact that drew me closer to Astronomy is that 'W𝘦 𝘢𝘳𝘦 𝘮𝘢𝘥𝘦 𝘰𝘧 𝘴𝘵𝘢𝘳 𝘴𝘵𝘶𝘧𝘧' (in the words of the famous Astronomer Carl Sagan). Have you ever wondered how the different extraterrestrial elements came to earth? The calcium in our bones, the iron in our blood, the gold that we wear as ornaments - all these were once part of stars somewhere in the Universe. When the stars exploded, it sent these materials flying into space. These elements could have been deposited on earth from visiting meteorites, comets or when the earth's core formed billions of years back.

On this sol in 168 (1926 October 27): BRITISH RADIO FANS LISTEN FOR MARS Hope for Signals While Planet Is Within 42,000,000Miles of the Earth. SCIENTISTS ON JUNGFRAU American Astronomer Finds Traces of Clouds and Atmosphere Indicating Some Life Exists. Copyright. 1926, by The/New York Times Company. Special Cable to The New York Times. LONDON, Oct. 26.— Many thousands of wireless fans and professional and amateur astronomers in this country will concentrate attention on Mars tomorrow night when that planet will be only 42,000,000 miles from the earth. Clouds which are predicted by the weather experts may spoil the plans of the astronomers, but the wireless fans will listen ir with great interest and at one place all wave lengths are to be explored ranging from 30 meters to 40,000 meters. But their hopes of getting into communication with Mars will receive scant support from the leading astronomers. Dr. A. C. Crommelin of the Greenwich Observatory says: "It is a practical impossibility that Mars, if intelligence exists on that planet, should think of sending and we should think of receiving signals at the same moment. Probably the same stage of scientific knowledge on the two planets would be reached millions of years apart even supposing Mara has inhabitants. If there are intelligent inhabitants on Mars they would have had our wireless knowledge millions of years ago.” H. H. Turner, Professor of Astronomy at Oxford University, expressed a similar view. He says it is conceivable, though unlikely, that Martians, if there are any, have tried to attract attention on the earth with signals which were never perceived and desisted long ago in despair. “There seems practically a certainty,” he adds, “that the histories of Mars and the earth are not marching in parallel. One planet is almost certainly older than the other, and planetary ages run into millions of millions of years.” —The New York Times, page 20

"A team of astronomers has found that Venus has never been habitable, despite decades of speculation that our closest planetary neighbor was once much more like Earth than it is today. The researchers, from the University of Cambridge, studied the chemical composition of the Venusian atmosphere and inferred that its interior is too dry today for there ever to have been enough water for oceans to exist at its surface. Instead, the planet has likely been a scorching, inhospitable world for its entire history. The results, reported in the journal Nature Astronomy, have implications for understanding Earth's uniqueness, and for the search for life on planets outside our solar system. While many exoplanets are Venus-like, the study suggests that astronomers should narrow their focus to exoplanets which are more like Earth." #venus #water
