Moreover, the sun's path over earth described a segment of a great circle ; ;

Aquarius is one of the oldest of the recognized constellations along the zodiac ( the sun's apparent path ).

The ability to achieve these goals simultaneously is fundamentally dependent on the seasonal variations in the sun's path throughout the day.

Preaching a message of universal love, he often presided over circle dances, which symbolized the sun's heavenly path across the sky.

The lunar nodes are the points where the moon's path in the sky crosses the ecliptic, the sun's path in the sky

Muslims pray ordinarily five times each day according to the sun's sky path regardless of clock time.

The nodes are where the moon's path crosses the ecliptic, the sun's path across the sky.

This is an imaginary line running due south from Beta Cassiopeiae through Alpha Andromedae to the celestial equator, at a point where the sun's path ( the ecliptic ) crosses it each autumn and spring equinox.

During each three-month period, the sun's path across the sky appears to form a closely wound quasi-helical shape, which can be likened to a spiral, so that three spirals could represent nine months, providing an explanation for a link between fertility and the triple-spiral symbol.

If time is the basis for house division, a difference must be made for whether the houses are based on invariant equal hours ( each house represents 2 hours of the sun's apparent movement each day ) or temporal hours ( daytime and night-time divided into six equal parts, but here the temporal hours will vary according to season and latitude.

The sun's position is taken as the ascendant of the chart and equal sized houses of 30 degrees each are used ; or alternatively, the sunrise chart can be used, with the sun's position at sunrise at the latitude in question taken as the ascendant.

Due to Mount Warning's proximity to Cape Byron, the Australian continent's easternmost point, it is the first place on mainland Australia to receive the sun's rays each day.

With some versions of this instrument, the sun's declination for each day of the year was marked on the arc.

Cadillac Mountain is commonly believed to be the first location in the United States to be struck by the sun's rays each morning.

In Egyptian mythology, the sun's emergence from the horizon each morning is likened to Ra's birth, an event that revitalizes him and the order of the cosmos.

The melanosomes in each recipient cell accumulate atop the cellular nucleus, where they protect the nuclear DNA from mutations caused by the sun's ionizing radiation.

Every four years, during which an extra 24 hours have accumulated, one extra day is added to keep the count coordinated with the sun's apparent position.

Some have countered this finding by saying that the angle of the film from the horizontal along with sun's angle on that day made shadows underwater unlikely.

Based partly on data taken from Pytheas, Hipparchus correlated cubits of the sun's elevation at noon on the winter solstice, latitudes in hours of a day on the summer solstice, and distances between latitudes in stadia for some locations.

The temple at Arasavilli was constructed in such a way that on the day of Radhasaptami, the sun's rays directly fall on the feet of the Sri Suryanarayana Swami, the deity at the temple.

( Of course, exactly the same motion occurs during the day, except that the stars are not visible because of the sun's glare, except during solar eclipses.

The cosine of the hour angle ( cos ( h )) becomes an easy computation tool in determining the cosine term for the computation of the angle of the sun's altitude ( or the complementary zenith angle ) at any time during the day.

Determining latitude was relatively easy in that it could be found from the altitude of the sun at noon with the aid of a table giving the sun's declination for the day.

The English noun Sunday derived sometime before 1250 from sunedai, which itself developed from Old English ( before 700 ) Sunnandæg ( literally meaning " sun's day "), which is cognate to other Germanic languages, including Old Frisian sunnandei, Old Saxon sunnundag, Middle Dutch sonnendach ( modern Dutch zondag ), Old High German sunnun tag ( modern German Sonntag ), and Old Norse sunnudagr ( Danish and Norwegian søndag, Icelandic sunnudagur and Swedish söndag ).

On the back of the mater there is often engraved a number of scales that are useful in the astrolabe's various applications ; these vary from designer to designer, but might include curves for time conversions, a calendar for converting the day of the month to the sun's position on the ecliptic, trigonometric scales, and a graduation of 360 degrees around the back edge.

Isidore of Seville explains that the quadriga represents the sun's course through the four seasons, while the biga represents the moon, " because it travels on a twin course with the sun, or because it is visible both by day and by night — for they yoke together one black horse and one white.

As it absorbed the sun's heat, the rod expanded downwards, cutting off the gas during the day.

At the time, the station was in an orbit exposed to the sun's light for 24 hours a day.

The surface of the Earth is heated unevenly by the Sun, depending on factors such as the angle of incidence of the sun's rays at the surface ( which differs with latitude and time of day ) and whether the land is open or covered with vegetation.

Aurelian is believed to have established the Dies Natalis Solis Invicti ( Day of the Birth of Sol Invictus ) as an annual festival held on the day when the sun's daily declination visibly starts rising again after the winter solstice, namely on December 25 ; the birth of the central figure was thus celebrated on the day which Christians later used to celebrate Jesus ' birth ( having always celebrated this at Epiphany ).

The sun's rays are able to penetrate the thin atmosphere producing relatively warm temperatures during the day ; however, the temperatures drop down to freezing at night.

: Everything is born out of the morning sun's bright rays and it is a new day for our nation.

Vegans who do not eat foods or pills fortified with synthetic vitamin D and with little exposure to the sun's ultraviolet radiation ( e. g., those who don't expose their extremities for at least 15 – 30 minutes per day or those living at latitudes close to the poles ) are vulnerable to Vitamin D deficiencies.

Because individuals with albinism have skin that entirely lacks the dark pigment melanin, which helps protect the skin from the sun's ultraviolet radiation, their skin can burn more easily from overexposure.

A burning glass or burning lens is a large convex lens that can concentrate the sun's rays onto a small area, heating up the area and thus resulting in ignition of the exposed surface.

Deviations from the ( evolving ) galactic average, locally-sampled around the time that the sun's nuclear burning began, can generally be accounted for by mass fractionation ( see the article on mass-independent fractionation ) plus a limited number of nuclear decay and transmutation processes.

Essentially a transition between the atmosphere and the magnetosphere, the ionosphere is where the atmosphere is thin enough that the sun's X-rays and UV rays can reach it, but thick enough that there are still enough molecules present to absorb those rays.

In these locations, one needs first to determine whether the sun is moving from east to west through north or south by watching its movements — left to right means it is going through south while right to left means it is going through north ; or one can watch the sun's shadows.

In the third phase of the simulation, the sun's rays have grown so powerful that soon even the white daisies can no longer survive.

Secchi disk readings do not provide an exact measure of transparency, as there can be errors due to the sun's glare on the water, or one person may see the disk at one depth, but another, with better eyesight, may see it at a greater depth.

Unlike with white sand beaches and Hawaii's green sand beach, walking barefoot on black sand can result in burns, as the black sand absorbs a great deal of the sun's energy.

Mitsukurina owstoni is found in the deep ocean, far below where the sun's light can reach at depths greater than 200 m. They can be found throughout the world, from Australia in the Pacific Ocean to the Gulf of Mexico in the Atlantic Ocean.

Unlike dunes made of quartz-based sand crystals, the gypsum does not readily convert the sun's energy into heat and thus can be walked upon safely with bare feet, even in the hottest summer months.

Nests of these ants are large, conspicuous, dome-shaped edifices, usually situated in woodland clearings, where the sun's rays can reach them.

David discovers Dr. Clive's laboratory, which contains a machine that can harness the sun's gamma radiation.

This can have profound effects on Earth's upper atmospheric regions, particularly during the peak of the sun's 11-year solar cycle when the greatest amounts of its energy are being released.

The Egyptians often described the sun's movement across the sky as the movement of a barque carrying Ra and his entourage of other gods, and the sun disk can either be equated with this solar barque or depicted containing the barque inside it.

A roof made of thermoplastic white vinyl, for example, can reflect 80 % or more of the sun's rays and emit at least 70 % of the solar radiation that the building absorbs.

A concave mirror, such as a polished soda can bottom, can be used as well to focus the sun's rays on tinder.

After taking care of his family's burial, Vittorio gathers what riches he can and prepares himself for adventure as he flees towards Florence, away from the perilous crowd of vampires, under the sun's protecting wing.
