The light is described as being created here before the sun, moon, and stars, which appear on the fourth day (Genesis 1:14–19). [10] In some Jewish interpretations, the light created here is a primordial light, different in nature from (and brighter than) that associated with the sun. [11]
[19] [20] Studies of the structure of the Kuiper belt and of anomalous materials within it suggest that the Sun formed within a cluster of between 1,000 and 10,000 stars with a diameter of between 6.5 and 19.5 light years and a collective mass of 3,000 M ☉. This cluster began to break apart between 135 million and 535 million years after ...
This model posits that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years. Many stars, including the Sun, were formed within this collapsing cloud. The gas that formed the Solar System was slightly more massive than the Sun itself.
It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its outer photosphere. Astronomers classify it as a G-type main ...
The hydrogen and most of the helium in the Sun would have been produced by Big Bang nucleosynthesis in the first 20 minutes of the universe, and the heavier elements were produced by previous generations of stars before the Sun was formed, and spread into the interstellar medium during the final stages of stellar life and by events such as ...
Quasars provide some additional evidence of early structure formation. Their light shows evidence of elements such as carbon, magnesium, iron and oxygen. This is evidence that by the time quasars formed, a massive phase of star formation had already taken place, including sufficient generations of Population III stars to give rise to these ...
But precisely how the sun generates the solar wind has remained unclear. New observations by the Solar Orbiter spacecraft may provide an answer. Sun-observing spacecraft sheds light on the solar ...
John Chrysostom read the passage similarly. 'Let there be light' (Gen 1:3) was about the creation of intelligible light, and it was also a universal light that came before the sun, moon, and so on. Augustine, noting that the creation of angels was not mentioned by Genesis, reads a reference to the creation of angels here. [24]
