Cameras can often capture colors in cases where the human eye does not distinguish them. The picture shows a meteor from the Quadrantid stream, photographed earlier this month in Missouri in the USA. It turned out to be not only very bright, but also multicolored.
A grain of sand, probably ejected from the asteroid 2003 EH1, left a trace in the earth’s atmosphere. The colors of meteors are usually caused by ionized elements evaporating during the destruction of meteors. Magnesium gives blue-green radiation, calcium – purple, and nickel – green.
The red glow is usually given by excited nitrogen and oxygen in the Earth’s atmosphere. The flash of this bright car lasted less than a second, but it left an ionization trail blown up by the wind, which was visible for several minutes.
