What will our Sun become in the first stage of its death?
Sun In about 5 billion years, when hydrogen fusion in its core has diminished to the point at which the Sun is no longer in hydrostatic equilibrium, its core will undergo a marked increase in density and temperature while its outer layers expand to eventually become a red giant. It is calculated that the Sun will become sufficiently large to engulf the current orbits of Mercury and Venus, and render Earth uninhabitable. After this, it will shed its outer layers and become a dense type of cooling star known as a white dwarf, and no longer produce energy by fusion, but
The Birth and Death of the Sun astrophysics, the sparkling humor, and the original drawings and graphs will be enjoyed by scientist and amateur alike." In April 2015, physicist and Nobel laureate Steven Weinberg included "The Birth and Death of the Sun" in a personal list of "the 13 best science books for the general reader". The Birth and Death of the Sun The Birth and Death of the Sun is a popular science book by theoretical physicist and cosmologist George Gamow, first published in 1940, exploring atomic chemistry, stellar evolution, and cosmology. The book is illustrated by Gamow. It was revised in 1952. Critical reception has
