First Solar Eclipse of 2011
The Link Between Organic and Inorganic Life: Has It Been Found?

Image of the Day: The Celestrial Poles from Mount Kilimanjaro

Space125-star-trails_30759_600x4501

Star trails create arches over the horizon in a long-exposure picture of the night sky taken from Mount Kilimanjaro in Tanzania. Equatorial regions, such as Kilimanjaro, are the only places on Earth where the celestial poles sit right at the horizon. At night the stars appear to drift overhead from east to west, completing a full circuit around the sky in 24 (sidereal) hours.The image shows the apparent motion of the stars around Polaris, the star that's almost exactly aligned with Earth's north celestial pole. Also called the North Star, Polaris is the brightest dot in the constellation Ursa Minor.

Yes an interesting image but totally ruined for me by the totally exasperating flashing add by ing( )direct right next to it!

I have to say it.....shouldn't it say "celestial" poles? :/

EM forces not gravity are at work with starlight reaching earth, a wavelength vibration of energy quanta or light, it bends freezes near magnetic fields actually inferred to exist black holes agn galaxy centers.

there are nice and perfect pictures, i took the frist my pictures from the eclipse, we saw 3 days ago.I'm interested in getting this pictures-the eclipse- thanks.

The word "poles" is used, suggesting that there should also be a southern (anti-Polaris) ring effect...

Are there photos of this as well?

To what cosmological object does the southern pole point to?

In the southern hemisphere, the navigational point of reference is the Southern Cross. (This is why there is a star pattern on the Australian Flag...in the Field of blue on the fly, there is a major star pattern: this is the Southern Cross.)
The orientation and position of the cross in the sky are constantly changing. It appears to rotate around a point in space known as the South Celestial Pole (it is in fact the earth that is rotating). During the night the orientation of the constellation changes in a regular manner from upright, to lying sideways, to upside-down. Both its position and orientation change over the course of a year. At midnight on 1 April it is upright and high in the sky, but three months later it is lying on its side in the south-west. It will be found upside-down and low in the sky at midnight on 1 October, and at midnight on 1 January it will be lying on its side in the south-east.
Finding south

There is no bright pole star in the southern hemisphere sky that can be used to locate due south in the same way that Polaris indicates north in the northern hemisphere. Instead, there are various ways of locating south by the Southern Cross.

First use the Southern Cross to locate the South Celestial Pole, then drop a vertical line from the South Celestial Pole to the horizon – this marks due south.

For the next person to come across this picture: Since Kilimanjaro is south of the equator, this is not a picture of Polaris. The Bright yellow star that starts at 12 o'clock with a trail heading clockwise, near the top of the picture ,is Alpha Centauri. The Southern cross appears to the right along the same arc.
