Can a computerized telescope replace charts? Not for beginners, I don’t think, and not on mounts and tripods that are less than top-quality mechanically (meaning heavy and expensive). And as Terence Dickinson and Alan Dyer say in their Backyard Astronomer’s Guide, “A full appreciation of the universe cannot come without developing the skills to find things in the sky and understanding how the sky works. This knowledge comes only by spending time under the stars with star maps in hand.” The paper proposes that Steve may be a form of “sub-auroral ion drift,” or SAID, in which an ionic gas travels quickly across the sky from east to west. SAID is similar to an aurora borealis—it also is a result of the interaction of charged solar particles and the Earth’s magnetic fields. This may surprise some people, but fish falling from the sky is common enough to be a well-documented meteorological event. And we only know about the ones that fall on populated land. The Earth’s shadow is the shadow that the Earth casts on its atmosphere. This atmospheric phenomenon is sometimes seen twice a day, around the times of sunset and sunrise. When the weather conditions and the observer’s viewing point permit a clear sight of the horizon, the shadow can be seen as a dark blue or greyish-blue band. Assuming the sky is clear, the Earth’s shadow is visible in the half of the sky opposite to the sunset or sunrise, and is seen as a dark blue band right above the horizon. A related phenomenon is the “Belt of Venus” or “anti-twilight arch”, a pink band that is visible above the dark blue band of the Earth’s shadow in the same part of the sky. There is no clear dividing line between the Earth’s shadow and the Belt of Venus: one colored band shades into the other in the sky.[15][16] Within visible-light astronomy, the visibility of celestial objects in the night sky is affected by light pollution. The presence of the Moon in the night sky has historically hindered astronomical observation by increasing the amount of ambient lighting. With the advent of artificial light sources, however, light pollution has been a growing problem for viewing the night sky. Special filters and modifications to light fixtures can help to alleviate this problem, but for the best views, both professional and amateur optical astronomers seek viewing sites located far from major urban areas. Sky luminance distribution models have been recommended by the International Commission on Illumination (CIE) for the design of daylighting schemes. Recent developments relate to “all sky models” for modelling sky luminance under weather conditions ranging from clear to overcast.[11] The sky can turn a multitude of colors such as red, orange, purple and yellow (especially near sunset or sunrise) when the light must pass through a much longer path (or optical depth) through the atmosphere. Scattering effects also partially polarize light from the sky and are most pronounced at an angle 90° from the sun. Scattered light from the horizon travels through as much as 38 times the atmosphere as does light from the zenith, causing a blue gradient: vivid at the zenith, and pale near the horizon.[8] Because red light also scatters if there is enough air between the source and the observer causing parts of the sky to change color during a sunset. As the amount of atmosphere nears infinity, the scattered light appears whiter and whiter.[9] By using a server created by MacDonald in 2014 called Aurorasaurus, amateurs from all over were able to upload interesting photos of sky phenomena. This crowdsourcing helped to make MacDonald’s study possible.

So faint are the stars that comprise this star pattern, we might refer to Cancer as an empty space in the sky. Because it contains no star brighter than 4th magnitude, the crab is difficult, if not impossible, to see under a light-polluted sky.  The Earth’s shadow is the shadow that the Earth casts on its atmosphere.

In Australian Aboriginal mythology, Altjira (or Arrernte) is the main sky god and also the creator god. In Iroquois mythology, Atahensic was a sky goddess who fell down to the ground during the creation of the Earth. Many cultures have drawn constellations between stars in the sky, using them in association with legends and mythology about their deities. For as little as $35 a year you can join us on our mission to protect the natural night sky. Once you get a telescope, to put it to good use you’ll need a detailed, large-scale sky atlas (set of charts). The basic standard is the Pocket Sky Atlas (in either the original or Jumbo Edition), which shows stars to magnitude 7.6. • Castor and Pollux shine together nearly overhead in the south after dark. Pollux is slightly the brighter of these “twins.” Draw a line from Castor through Pollux, follow it farther out by a big 26° (about 2½ fist-widths at arm’s length), and you’re at the dim head of Hydra, the Sea Serpent. In a dark sky it’s a subtle but distinctive star grouping, about the size of your thumb at arm’s length. Binoculars show it easily through light pollution or moonlight.
