Later, astronomers adopted the term and "light-years" quickly became standard to help make sense of the massive distances between basically everything in our vast universe. How Far Is One Light-year? So what ex
While astronomy is a branch of science, astrology has nothing to do with the scientific method and is an entirely different thing. In fact, the only thing astronomy and astrology have in common are the "astro" element of their name, which is from the Greek "astron," meaning "star." Othe...

Seasons are explained by astronomers. As an artifact of our global tilt, and as the Earth moves around the Sun once every year, the Sun shines sometimes more on the Northern Hemisphere (our summer) and sometimes more on the Southern Hemisphere (our winter). And between each of these two ...
Why do astronomers use light-years? What is electron configuration and its importance? Why do the most luminous stars end their lives on the main sequence the quickest? A typical photo-voltaic cell delivers 4.2 10^-3 W of electric energy when illuminated with...
