Season to Season: Earth's Equinoxes & Solstices #Infographic

All the planets in one picture...

Equinoxes occur when the Sun crosses the celestial equator. The ecliptic (broken line) is the apparent path of the Sun as the Earth orbits. The celestial equator is the projection of Earth's equator into space as part of a sky coordinate system - like a map grid on Earth. ©Mona Evans, "Autumnal Equinox"


In 79 AD, Mt. Vesuvius exploded w/the energy of 1000 nuclear bombs. It killed about 16,000 people as rock & ash poured out of it at a rate of more than a million tons per second. It was so devastating that it has become an icon of the terror of an active volcano. NASA Photo
