Instead of the prevailing cosmogony in which eclipses were caused by Rahu and Ketu (identified as the pseudo-planetary lunar nodes), he explains eclipses in terms of shadows cast by and falling on Earth. Thus, the lunar eclipse occurs when the Moon enters into the Earth's shadow (verse gola.37).
Numerous interactions with the Mauryan Empire, and the later expansion of the Indo-Greeks into India suggest that transmission of Greek astronomical ideas to India occurred during this period. [45] The Greek concept of a spherical Earth surrounded by the spheres of planets, further influenced the astronomers like Varahamihira and Brahmagupta .
Scientists from India also appeared throughout Europe. [134] By the time of India's independence colonial science had assumed importance within the westernized intelligentsia and establishment. French astronomer, Pierre Janssen observed the Solar eclipse of 18 August 1868 and discovered helium, from Guntur in Madras State, British India. [134]
For six minutes, the longest eclipse since 1416, the Moon would completely block the face of the Sun, pulling a curtain of darkness over a thin stripe of Earth.
1868 – Jules Janssen observes a bright yellow line with a wavelength of 587.49 nanometers in the spectrum of the chromosphere of the Sun, during a total solar eclipse in Guntur, India. Later in the same year, Norman Lockyer observed the same line in the solar spectrum, and concluded that it was caused by an element in the Sun unknown on Earth.
Eclipses have always brought with them a heady mix of science and superstition, but today, thanks to education and the media, nearly everyone knows what an eclipse is and how to view one safely.
The eclipse begins at 6:25p.m. EST, and the total eclipse starts at 7:34 p.m. EST. Total solar eclipses can inspire a certain amount of awe, but they're nothing to be scared of.
By the 5th century: The decimal separator is developed in India, [76] as recorded in al-Uqlidisi's later commentary on Indian mathematics. [77] By the 5th century: The elliptical orbits of planets are discovered in India by at least the time of Aryabhata, and are used for the calculations of orbital periods and eclipse timings. [78]
