NGC 2903

On this page I collect my observations of the barred spiral galaxy NGC 2903 in the constellation Leo.

Introduction

The barred spiral galaxy NGC 2903 in the constellation Leo is one of the brighter spiral galaxies. It is unclear why Messier missed it... The catalog entry NGC 2905 is related to NGC 2903, as it describes a star-forming region near the northeastern edge of NGC 2903.

East of NGC 2903, there is the spiral galaxy NGC 2916, which is located at a distance of more than 160 million light years from us.
