In another eclipse in 1869, astronomers found convincing evidence of another new element, which they nicknamed coronium—before learning a few decades later that it was not a new element, but ...
A difference in the observed position of the stars during the eclipse, compared to their normal position (measured some months earlier at night, when the Sun is not in the field of view), would indicate that the light from these stars had bent as it passed close to the Sun. Dyson, when planning the expedition in 1916, had chosen the 1919 ...
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.

The line was detected by French astronomer Jules Janssen during a total solar eclipse in Guntur, India. The first direct measurement of the distance to a star ( 61 Cygni at 11.4 light-years ) was made in 1838 by Friedrich Bessel using the parallax technique.
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.
Varāhamihira goes on to state that "The Greeks, indeed, are foreigners, but with them this science (astronomy) is in a flourishing state." [ 9 ] Another Indian text, the Gargi-Samhita , also similarly compliments the Yavanas (Greeks) noting they, though barbarians, must be respected as seers for their introduction of astronomy in India.
When a total solar eclipse approached France in 1654, an anonymous pamphlet attributed to the astronomer Pierre Gassendi tried to reassure residents of Paris that the eclipse would bring no harm.
