| Object | NGC 5078 & NGC 5101 |
| Info |
NGC 5078 ( R/H side) Is a lenticular (lens-shaped) edge on galaxy that is located in the constellation Hydra. This image shows the dust lane being warped and dispersed due in all probability to the gravitational tidal effects caused by its interaction with the fainter and distorted 'S' shaped galaxy IC 879. It is likely that the dust lane of NGC 5078 is the remnant of a dusty spiral which fell into it long ago. NGC5101(L/H side) is also a lenticular galaxy but face on. This galaxy is classified as a Sba (spiral barred) with morphology as nucleus, bar, lens, inner ring and outer pseudo ring. It shows NII but has no Ha to it's structure . |
