描述

A Hubble Space Telescope view of a small portion of the Orion Nebula, captured by the Wide Field and Planetary Camera 2, reveals five young stars. Four of the stars are surrounded by gas and dust trapped as the stars formed, but were left in orbit about the star. These are possibly protoplanetary disks, or proplyds, that might evolve on to agglomerate planets. The proplyds which are closest to the hottest stars of the parent star cluster are seen as bright objects, while the object farthest from the hottest stars is seen as a dark object. The field of view is only 0.14 light-years across.

The Orion Nebula star-birth region is 1500 light-years away, in the direction of the constellation Orion the Hunter.

العربية: صورة هابل لأقراص الكواكب الأولية في سديم الجبار، وهو «حضانة نجمية» تمتد على مدى سنوات ضوئية من المحتمل أن تكون مشابهة جدًا للسديم الأولي الذي تشكلت منه الشمس.
