A Galactic Light Show In Spiral Galaxy Ngc 4258. Poster
- from our Affiliates
A galactic light show in spiral galaxy NGC 4258, also known as M106, about 23 million light years away. This galaxy is famous, however, for something that our galaxy doesn't have – two extra spiral arms that glow in X-ray, optical and radio light. These features, or anomalous arms, are not aligned with the plane of the galaxy, but instead intersect with it.
