This is the beautiful edge on spiral galaxy NGC 5775 located approximately 85 million light years distant in the constellation Virgo where it’s a member of the Virgo Supercluster of galaxies. Any time you get to view a galaxy edge on like we have here in NGC 5775 is a terrific opportunity to study the profile of the galaxy itself. In this Hubble Space Telescope image a number of things are apparent here. One is that there appears to be a bright core though much of its optical light is shrouded by material along the plane of the disk. Another notable feature is that gas and dust as this galaxy houses vast lanes of gas and dust and because of that it’s not difficult to see the extremely high number of star forming regions in the form of fire-like pockets of light throughout the disk of the galaxy.
Also, though not in this photo, is a nearly face-on spiral galaxy cataloged as NGC 5774 that NGC 5775 is interacting with. The two make a striking pair but because of the low surface brightness of NGC 5774 it’s a tough target in smaller telescopes. The two galaxies are alto interacting; when seen in different wavelengths a bridge can be seen stretching from one galaxy to the other as material connects the two.
