Chemicals Glow as a Meteor Disintegrates
Explanation: Meteors can be colorful. While the
human eye usually cannot discern many colors, cameras often can.
Pictured here is a
fireball, a disintegrating meteor that was not only one of the brightest the photographer has
ever seen, but colorful. The meteor was captured by chance in mid-July with a camera set up on
Hochkar Mountain in
Austria to photograph the central band of our
Milky Way galaxy. The
radiant grit, likely
cast off by a comet or asteroid long ago, had the misfortune to enter
Earth's atmosphere.
Colors in meteors usually originate from ionized chemical elements released as the
meteor disintegrates, with blue-green typically originating from
magnesium,
calcium radiating violet, and
nickel glowing green. Red, however, typically originates from energized
nitrogen and
oxygen in the Earth's atmosphere. This bright
meteoric
fireball was gone in a flash -- less than a second -- but it left a
wind-blown ionization trail that
remained visible for almost a minute.
