Auroras meteors and other atmospheric phenomena

Auroras, Meteors, and Other Atmospheric Phenomena

rainbows, sun dogs, halos, and lunar and solar coronas


Auroras

Auroras

  • Auroras originate with the sun.

  • Titanic explosions on the sun eject charged particles into space and some hit our planet.

  • The particles cause the air to glow - what we call auroras.


Rainbows

Rainbows

  • Rainbows are caused by rain drops in the air.

  • These rain drops break light down into its many colors.

  • When we see the reflected light, we see sun’s spectrum


Sundogs

Sundogs

  • Sun dogs work much like rainbows, but the spectrum is caused by ice crystals high up.

  • Six-sided ice crystals produce the spectrum and scatter sun’s light.


Halos and coronas

Halos and Coronas

  • Halos around the sun an moon are nothing more than complete sundogs - or moondogs!

  • Coronas are caused only by light scattering.


Meteors

Meteors

  • Meteors often arrive from space as meteor showers.

  • Meteors are caused by debris from passing comets.

  • The debris falls to Earth as a hot, shining streak.


Comets

Comets

  • Frozen remains from the formation of our solar system.

  • While not normally found in our planet’s atmosphere, comets can crash to earth.

  • One probably did so in northern Russia in the year 1908.
