Astronomers have been trying to figure out the number
More than 90 percent can't be seen
العلماء كانوا يحاولون معرفة عدد المجرات الموجودة
اكثر من 90% منها غير مرئية
(CNN)Turns out we were wrong; there aren't 200 billion galaxies in the universe.
تبين اننا كنا على خطا فعدد المجرات في كوننا ليس 200مليار كما كان يعتقد سابقا
It's more like 2 trillion.
Yes, TRILLION!
بل هو اكثر من 2 ترليون (اي ألفي مليار)
That's the latest from NASA, which announced Thursday the number of galaxies in our observable universe is 10 times higher than previously projected.
هذا ما اعلنته وكالة ناسا يوم الخميس الماضي بان عدد المجرات التي يمكن رصدها في كوننا هي اكثر عشر أضعاف العدد الذي كنا نعتقده
This revelation was possible, thanks to that font of discovery -- the Hubble Space Telescope.
وقد تم التوصل الي هذه النتيجة بفضل التلسكوب هابل
Astronomers have been trying to figure out the number of galaxies for decades.
علما بان علماء الفضاء ظلوا يحاولون معرفة عدد المجرات في كوننا منذ سنين طويلة
In the mid-1990s, they arrived at the 200 billion figure (again, thank you Hubble.)
وفي وسط التسعينات من القرن الماضي توصلوا الي رقم 200 مليار وذلك بفضل التلسكوب هابل أيضاً

Arriving at the number
Recently, however, a team led by Christopher Conselice at the University of Nottingham in the U.K. decided to take another crack at it.
It concluded that one point long, long, long ago, many of the galaxies were packed together. Some were tiny and faint and were swallowed by larger galaxies. As this happened, the population density of galaxies in space dwindled.
The team looked at old Hubble photos and newer images. Then, it used new mathematical models and inferred how many galaxies are out there that can't been by current telescopes.
Its conclusion? More than 90 percent of the galaxies can't be seen by even our most powerful telescopes because they are too faint or too far away.
"It boggles the mind that over 90 percent of the galaxies in the universe have yet to be studied," Conselice said.
There's good news: There's a bigger, badder telescope in the works. The James Webb Space Telescope will be able to peer back to the dawn of time. It should be ready by the end of the year
