M33 The Pinwheel Galaxy in Triangulum

With nebulous hydrogen regions emphasized

The goal of this image was to show more clearly the large nebulous regions in this nearby galaxy. By using images taken through a Hydrogen Alpha filter blended with the RED channel data, the hydrogen nebulae are displayed as the bright red regions in the galactic arms.

These nebulae are likely to be very similar to the large nebulae found in our Galaxy such as NGC7000 (North American Nebula), NGC5070 (The Pelican Nebula) and other such objects. Because M33 is comparatively close to our galaxy, the Milky Way, these nebulous regions can be directly observed from ground-based instruments.
