اسمحوا لي انا اعلق علي هذه المقالة ولا اخفى عليكم مدى ضجري وثورتى عندما قرأت هذة المقالة حيث انني توهمت اني رجعت الى عصور الجاهلية والتخلف وما زاد اضطراب نفسى ان تنسب المقالة الخطء ترجمتها الي الأسلام وكأن المسلمون اطفال بلهاء يلهثون وراء الحلوى حتى وان كانت فاسدة
يا اخوان ديننا هو الحق ومن شاء فليأمن ومن شاء فليكفر.وان كان الغرض من المقالة هو الموعظة للمسلمين فيجب ان تكون الأحداث المنقولة صحيحة مئة بالمئة حتى لا تفقد مصداقيتها عند العامة.
لذلك ارجو عند نقل اى مقالة كالتى اعلق عليها الأن ان تبدا بقول"يا اهل العلم لقد قرأت او سمعت كذا فأفيدونا عن صحتها....." و لابد ان يذكر المصدر لها

عندما قرأت الرسالة تخيلت أجنبى كافر يفرأها ويقول ما اشد تخلف المسلمين ماذالو يفسرون الظواهر الكونية بالخرافات والخزعبلات ليثبتو ان دينهم هو الحق ثم يتعجب عندما يعلم ان هذا التحليل لم يخرج عن عالم مسلم بل هو منقول خطأ من موقع غربي فينظر اى في احتقار ويمضى.

Spacewatch Friday: Reverse Course! Mars Motion Soon to be Backward

As Mars has grown closer and brighter daily for several months, it has gradually moved easterly in relation to background stars in the pre-dawn sky. That's about to change as the red planet begins to backpedal in our sky, moving steadily westward.

Astronomers call this backward motion "retrograde." The shift comes as Mars is gradually becoming visible in the late evening, too, just in time for the historic close approach to Earth that will occur in late August.

Mars is already rising before midnight, blazing in the southeast skies like a pale red or sometimes yellowish-orange lantern.

At the beginning of this year, Mars was 191 million miles (306 million kilometers) from Earth. This week, the distance will drop to less than 40 million miles (64 million kilometers).

Mars now shines some 30 times brighter than it did on New Year's Day.

.Since Jan. 1, the red planet has progressed along an easterly course through the background stars of the Zodiac. The motion is not noticeable in a single morning, but could be detected from one to the next by astute observers.

For the past few weeks, Mars has appeared to slow in its eastward trajectory, almost seeming to waver, as if it had become uncertain.

On Wednesday, July 30, that steady eastward course will come to a stop. Then, for the next two months, the planet will move backward against the star background - toward the west. On Sept. 29 it will pause again before resuming its normal eastward direction.

All the planets exhibit retrograde motion at one time or another. Ancient astronomers were unable to come up with a satisfactory explanation for it. The motion is tricky. For one thing, while behaving in this strange manner, Mars will also appear to deviate somewhat from its normal course; the retrograde motion will appear to bring it a little below its regular orbital track.

In other words, as seen from Earth, Mars will appear to travel in a loop.

Yet the Greeks staunchly believed that the Sun, Moon and planets all moved around the Earth in perfect circles. They had a great difficulty in representing and calculating this mysterious loop and for a long time they had no adequate explanation for it.

The Greeks finally explained away this anomaly by assuming that the planets moved around the Earth in smaller "epicycles" - that is, a small circle whose center moves along its main orbital circle around Earth, resulting in complex, almost coil-like curves. Unfortunately, the actual observations of the planets never seemed to fit this strange orbital mechanism, ultimately making the Greeks explanation quite useless.

It was not until the year 1543 when the great Polish astronomer, Nicolaus Copernicus (1473-1543), had his lifelong work "De revolutionibus" published, that the secret of the odd retrograde loops were finally revealed.

By demoting the Earth from its hallowed position at the center of the solar system and replacing it with the Sun, Copernicus was able to triumphantly explain the riddle of the apparent "backwards motion effect" of the planets.

It's the same effect obtained when one car passes another on the highway: both cars are going in the same direction, but one is moving more slowly. To an observer with no other reference points, as they pass, the slower car will appear to be moving backward in relation to the faster one. Copernicus simply applied the same effect (though he probably wasn't thinking of automobiles) to the planets out in space.

Right now, both Earth and Mars are moving in the same direction around the Sun, but the slower one - Mars - appears to move backwards compared to the faster one, the Earth.

This backward motion will manifest itself after Mars arrives at its first stationary point on July 30. Mars will then begin to loop back toward the west. Earth will overtake Mars on Aug. 28.

Finally, on Sept. 29, the combined movements of Earth and Mars will cancel-out the apparent backward motion, with Mars reaching a second stationary point. From then on, Mars will loop back to the east, resuming its normal path among the stars.

ولن اترجم المقالة وسأدعها لأى استاذ لغه أنجليزيه أو خبير فى اللغه الأنجليزيه لترجمتها ترجمة صحيحة ويزكر انها ظاهرة كونية طبيعية متكررة الحدوث وان كان قدماء اليونان قاموا بتفسيرها خطأ لكن اكتشاف
Nicolaus Copernicus قد كان حجر الزاوية في التحليل الصحيح للظاهرة

وعندما تعرفوا الحقيقة وما كونها الا خداع بصرى ستكتشفوا لماذا كان غضبى
"عدم ترجمتى للمقالة لتحريك روح البحث والأطلاع وايمانا منى بمقولة ما أخذ سهلا ضاع سهلا"
اعذرونى على لهجتى الغاضبة
