AURORA

An aurora (plural: aurorae or auroras; from the Latin word aurora, "sunrise") is a natural light display in the sky particularly in the high latitude (Arctic and Antarctic) regions, caused by the collision of energetic charged particles with atoms in the high altitude atmosphere (thermosphere). The charged particles originate in the magnetosphere and solar wind and, on Earth, are directed by the Earth's magnetic field into the atmosphere. Aurora is classified as diffuse or discrete aurora. Most aurorae occur in a band known as the auroral zone,[1][2] which is typically 3° to 6° in latitudinal extent and at all local times or longitudes. The auroral zone is typically 10° to 20° from the magnetic pole defined by the axis of the Earth's magnetic dipole. During a geomagnetic storm, the auroral zone expands to lower latitudes.

Lunar Eclipse

Lunar eclipse is sky events that is easy to observed. You just go out to see it, don’t need binoculars or a telescope or other special equipment to see it.
Lunar eclipse has no harmful effects when we see it with the naked eye, so you don’t need to use glasses.

A lunar eclipse occurs when the full Moon lines up precisely with the Earth and the Sun, and the Earth's shadow falls on the Moon. Greek astronomers had figured that out over 2000 years ago, and knew that the curved shadow on the Moon indicated that the Earth was a sphere.

Sun Phenomena called as "SUNDOG"

From the title, I guess that you have some question about SUNDOG, exactly what is SUNDOG ? Why this phenomena happen ? What is the causes ? Right, this is my question too at first I read this article. I will tell you What Is SUNDOG. SUNDOG is one of phenomena that happen in our atmosphere that can make light shining through ice crystals in the cloud _, much like light shining through raindrops makes a rainbow.
