Hubble, the Man and the Machine

I believe most of us have heard about

Hubble Telescope.

It is a space telescope that was carried into orbit

by the space shuttle in 1990.

Although not the first space telescope,

the Hubble is one of the largest and most versatile.

It provided scientist with huge amount of

data and never seen before images

that resulted in better understanding of the universe.

Hubble's ultra deep field images has shown us

thousands of galaxies that are 13 billion light years away,

the furthest and oldest galaxies ever seen.

Since its launch, it had 5 servicing missions.

The last one was in May 2009

which made many repairs and upgrades that

will allow it to be functional till the year 2014,

when its successor the James Web Space Telescope

is due to be launched.

Now, who is Hubble ?

How many of you knows anything about him?

What made NASA name its most important telescope after him ?

Edwin Hubble (1889-1953) is an American Astronomer

who contributed greatly to astronomy.

Until the year 1922, all scientists believed that

the universe was only one galaxy, our own Milky Way Galaxy.

Hubble discovered (announced in 1925)

that there are more galaxies in the Universe

and that our universe is much larger than what they thought.

His next discovery was Hubble's Law

which proved that the Universe is expanding.

Actually Albert Einestien and

according to his theory of general relativity in 1917,

concluded that the universe should be either expanding or contracting.

But that conflicted with the previous believe that the universe was still.

So Einestien changed his equations and when he heard of Hubble discovery said

that changing his equation was the greatest blunder of his life.

This discovery of the expansion of the universe had led

later to the Big Bang Theory.

خاطرة

تذكرت عقب ما شفت هالفيديو الاية الكريمة

أَأَنتُمْ أَشَدُّ خَلْقًا أَمِ السَّمَاءُ بَنَاهَا ﴿٢٧﴾ رَفَعَ سَمْكَهَا فَسَوَّاهَا ﴿٢٨﴾ وَأَغْطَشَ لَيْلَهَا وَأَخْرَجَ ضُحَاهَا

طبعا كلنا شفنا اكتشاف العلماء لضخامة حجم الكون

و الارقام المذكورة لا يستطيع العقل البشري استيعابها او تصورها و تخيلها

وهذا يدل على كم هو الانسان ضئيل و صغير في هذا الكون

و مع ذلك اختار الله سبحانه و تعالى

ان تسجد له الملائكة تكريما له

و ذلك لسبب واحد

هو العقل و العلم

فأين نحن من العلم ؟

سؤال

هل تعتقدون اننا وحيدون في هذا الكون ؟؟
