Messier 74, also known as the Phantom Galaxy, is seen here in infrared light which showcases its sweeping spiral arms and star-forming regions. This image was created using archival data from NASA's Spitzer Space Telescope, revealing dust clouds that, in visible light, appear dark.

Messier 74 is an archetype of the "grand design" spiral galaxy and is nearly face-on to our view, providing a perfect view of its structure. In this infrared image, the light from stars appears blue, as stars are brightest at shorter wavelengths of infrared light and less visible at longer wavelengths. The dust clouds, which light up at longer wavelengths of light, are rendered as red.

Filamentary dust clouds are a feature of spiral arms, and help to trace regions where gas reaches higher densities and can lead to the formation of stars.

The galaxy is located in the Pisces constellation and is situated about 30 million light-years away. It has a visible diameter of approximately 10 arc minutes, which is about a third as wide as the full moon. However, its low surface brightness makes it too faint to be seen with the naked eye and makes it a challenging target even for small backyard telescopes.

In this image, infrared light at wavelengths of 3.6, 4.5, and 8.0 microns is displayed as blue, green, and red, respectively.
