A halo (ἅλως; also known as a nimbus, icebow or gloriole) is an optical phenomenon produced by the interaction of light from the Sun or Moon with ice crystals in the atmosphere, resulting in colored or white arcs, rings or spots in the sky. [23]
Optical phenomena are any observable events that result from the interaction of light and matter. All optical phenomena coincide with quantum phenomena. [ 1 ] Common optical phenomena are often due to the interaction of light from the Sun or Moon with the atmosphere, clouds, water, dust, and other particulates.
Representation of upper-atmospheric lightning and electrical-discharge phenomena Discovery image of a TLE on Jupiter by the NASA Juno probe. [1]Upper-atmospheric lightning and ionospheric lightning are terms sometimes used by researchers to refer to a family of short-lived electrical-breakdown phenomena that occur well above the altitudes of normal lightning and storm clouds.
The Aurora Borealis, also known as the "Northern Lights", illuminate the sky as people gather to watch the annual Perseid meteor shower near the village of Borodinka in the Omsk region, Russia ...
The rare light spectacle has caused a bit of buzz this year as the sun is entering its most active period, ramping up the number of dazzling natural phenomena that appear in the night sky — and ...

Alpenglow; Anthelion; Anticrepuscular rays; Aurora (northern and southern lights, aurora borealis and aurora australis) Belt of Venus; Brocken Spectre; Circumhorizontal arc; Circumzenithal arc; Cloud iridescence ...
The northern lights appear in the sky when charged particles spew from the sun during solar storms, making colorful light displays when clouds of those particles collide with Earth's magnetic ...
The phenomena [sic] of false suns which sometimes attend or dog the true when seen through the mist (parhelions). In Norfolk a sun-dog is a light spot near the sun, and water-dogs are the light watery clouds; dog here is no doubt the same word as dag, dew or mist as "a little dag of rain" (Philolog. Soc. Trans. 1855, p. 80). Cf. Icel.
