مجال هبل العميق

The Hubble Deep Field

حقل هابل العميق Hubble Deep Field هوبقعة سماوية مثيرة تحتوى على أكثر من الف مجرة لم يرها أحد من قبل .ففى ديسمبر -كانون الأول من سنة 1955م ركز تلسكوب الفضاء هابل على بقعة سماوية واحدة لمدة عشرة ايام متتالية فكشف عن وجود 1500 مجرة على أقل تقدير من مراحل نشوء مختلفة .

بعض تلك المجرات خافت أربعة مليارات مرة أكثر مما تستطيع العين المجردة رؤيته ويعود الى بداية الكون تقريبا إذا اكتشاف هذا الحقل وفر لفهماء الكون مادة كونية مهمة لدراسة عدد المجرات الموجودة في الكون وكيفية تكونها.

The dramatic improvement in Hubble's imaging capabilities after corrective optics were installed encouraged attempts to obtain very deep images of distant galaxies.

اختيار الهدف

The HDF is at the centre of this image of one degree of sky

ملاحظات

The HDF was located in Hubble's northern Continuous Viewing Zone, as shown by this diagram.

تجهيز البيانات

A section of the HDF about 14 arcseconds across in each of the four wavelengths used to construct the final version: 300 nm (top left), 450 nm (top right), 606 nm (bottom left) and 814 nm (bottom right)
