The first major Arabic work of astronomy is the Zij al-Sindh by Muhammad ibn Musa al-Khwarizmi. The work contains tables for the movements of the Sun, the Moon, and the five planets known at the time. The work is significant as it introduced Ptolemaic concepts into Islamic sciences. This work also marks the turning point in Arabic astronomy.
Robert Bunsen and Gustav Kirchhoff further develop the spectroscope, which they used to pioneer the identification of the chemical elements in Earth, and also in the Sun. [32] Around 1862 Father Angelo Secchi developed the heliospectrograph, enabling him to study both the Sun and the stars, and identifying them as things intrinsically of the ...

Henrietta Swan Leavitt (/ ˈ l ɛ v ɪ t /; July 4, 1868 – December 12, 1921) was an American astronomer. [2] [1] [3] Her discovery of how to effectively measure vast distances to remote galaxies led to a shift in the scale and understanding of the scale and the nature of the universe. [4]
c. 250 BCE – Following the heliocentric ideas of Aristarcus, Archimedes in his work The Sand Reckoner computes the diameter of the universe centered around the Sun to be about 10 14 stadia (in modern units, about 2 light years, 18.93 × 10 12 km, 11.76 × 10 12 mi). [27]
With the help of two powerful radio telescopes, astronomers spotted the gigantic two-lobed jet, which spans at least 200,000 light-years. A light-year is the distance light travels in one year ...
Sacrifices of “sun stones” occurred around the same time a volcanic eruption in 2900 BC dimmed the sun throughout Northern Europe, according to a new study.
