The Sun is a 2017 popular science book by Leon Golub and Jay Pasachoff. It describes the current scientific understanding of the structure of the Sun and its influence on Earth's processes. The book contains numerous illustrations, as well as tips on observing the Sun and related astronomical phenomena.
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. [1] The book is illustrated by Gamow. It was revised in 1952.
Solar cycles are nearly periodic 11-year changes in the Sun's activity that are based on the number of sunspots present on the Sun's surface. The first solar cycle conventionally is said to have started in 1755. The source data are the revised International Sunspot Numbers (ISN v2.0), as available at SILSO. [1]
This book was written before computer programmes were available, so it gives the detail needed to make the calculations manually.Cited in more than 1,381 publications between 1961 and 1975.

The Sun, taking along the whole Solar System, orbits the galaxy's center of mass at an average speed of 230 km/s (828,000 km/h) or 143 mi/s (514,000 mph), [168] taking about 220–250 million Earth years to complete a revolution (a Galactic year), [169] having done so about 20 times since the Sun's formation.

400 year sunspot history, including the Maunder Minimum "The prediction for solar cycle 24 gave a smoothed sunspot number maximum of about 69 in the late Summer of 2013. . The smoothed sunspot number reached 68.9 in August 2013 so the official maximum was at least that h
In 2002, Lean et al. [41] stated that while "There is ... growing empirical evidence for the Sun's role in climate change on multiple time scales including the 11-year cycle", "changes in terrestrial proxies of solar activity (such as the 14C and 10Be cosmogenic isotopes and the aa geomagnetic index) can occur in the absence of long-term (i.e ...
