All the energy that is put into the oxygen atom is lost before the 0.7-second lifetime allows radiation.

These lights are called auroras. Lancaster University's Department of Physics runs a website called AuroraWatch UK, which estimates the likelihood of an aurora being visible based on geomagnetic activity. And the Jupiter lights aren't just driven by the solar wind: Most of the particles that cause the planet's auroras are blasted into space by its close-orbiting moon Io, the most volcanic body in the solar system. The latter process is the same driver of the aurora, making STEVE a special kind of aurora hybrid. In ancient times when the aurora appeared overhead, people often associated the aurora with good or bad omens and sometimes considered it a manifestation of activities of heavenly spirits or gods. When an atom or molecule emits light as a photon, to rid itself of its excess energy, that photon has a wavelength that is characteristic for that atom. $17.37, $19.30 (15% off), Sale Price $3.60 danicaalvarez11 Dec 1, 2021.
