Orion Nebula

Orion nebula


This dramatic image offers a peek inside the Orion Nebula, also known as Messier 42. Made by stitching together 520 images taken by the Advanced Camera for Surveys (ACS) aboard NASA’s Hubble Space Telescope, this represents the sharpest view ever taken of this region. More than 3,000 stars of various sizes appear in this image. Some of them have never been seen in visible light. The bright patch near the centre is the Trapezium Cluster, intense young stars whose ultraviolet light has carved out a cavernous space from the surrounding dust and gas. Another star-forming region, Messier 43, is at top left. The nebula is easy to see on a clear night, despite being over 1500 light years away. This patch of sky appears about the same size as a full Moon.
