"Experts Dispute Accuracy of Eclipse Path Maps"

A new map by eclipse calculator John Irwin suggests that the path of totality for the 2024 total solar eclipse may be slightly narrower than previously thought due to a more precise calculation of the sun's size, affecting cities on the edge of the path. However, NASA's eclipse predictions have not changed, and the difference would only impact cities on the very edge of the path of totality. The total solar eclipse will be visible in the United States from Texas to Maine, with safety tips and the reminder that the next opportunity to watch a total solar eclipse from the contiguous United States won't be until August 23, 2044.

Reevaluating the Sun's Size: Surprising Discoveries Unveiled

New measurements using solar wave oscillations confirm that the sun is slightly smaller than previously thought, with a radius of about 432,337.6 miles (695,780 km). These precise measurements are important for understanding the sun's physics and atmosphere, as they provide insights into its nuclear reactions, chemical composition, and basic structure. The accurate radius is crucial for avoiding misleading conclusions about the sun's internal structure and for studying phenomena such as magnetic storms and solar winds that can impact Earth.
