... Credit Copyright: Peter Wienerroither ( U. Wien ) Explanation: You could be the first person ever to take a real single-exposure image like this. The above image from Vienna, Austria is not real in the sense that the 360 degree star trails in the sky appear only because of a digital trick. ... Walter Lewin , though, has asked APOD to pose this as a challenge to astrophotographers : create a real single-exposure image of a clear night sky that features 360 degree star trails. ...

... In polar coordinates, the point P is defined by its distance r from the origin O (see drawing) and by its polar angle ("azimuth" on a map) between the x-axis and the "radius" r = OA, measured counter-clockwise. ... When one or both are negative , the angle f is larger than 90 degrees, and such angles never appears in any right-angled triangle. ... There is a simple solution , though: use the above equations to re-define sin f and cos f for such larger angles! ... But it also works for larger angles....

Gaps in the Magellan coverage were filled with images from the Earth-based Arecibo radar in a region centered roughly on 0 degree latitude and longitude, and with a neutral tone elsewhere (primarily near the south pole). ...

They are now viewed as new definitions of the sine and cosine, for the polar angle f given by x and y ( a slightly different way of formulating this definition is described further below ). ... sin 2 f + cos 2 f = 1 . ...

... This document and the attached postscript figure document an analysis that I did to determine the optimum midpoint and required ranges for both the rotator and azimuth for the 2.5 M telescope. ... I simulate a series of drift scans on the sky for tracks that cover the northern survey area. These tracks cover the range in survey latitude of -60 to +60 degrees, spaced by 10 degrees. ... Along each track the azimuth, elevation, and position angle of the CCD is computed at 1 minute intervals. ...

Lunar Libration . Articles | ... Actually, a slight rocking motion, called libration,* makes about 59% of the Moon's surface visible from our planet Earth -- though only 50% at any one time. ... Add to that, the approximate 1.5 degree tilt of the Moon's equator to the ecliptic, and you have the inclination of the Moon's equator to the plane of its orbit around Earth at some 6.5 degrees (5 + 1.5 = 6.5). ...

Springtime in the Solar System . In our case, we can use the tilt theory of the seasons to make a prediction: that any tilted planet will have seasons, and that the strength of these seasons will depend on the amount of the tilt. ... At summer solstice, the north pole points straight at the Sun; the north polar regions have tropical weather, but the Southern Hemisphere is in total darkness. ... With a little trigonometry, you can calculate the angle of the Sun and the intensity of solar heating. ...
