Galaxies in Virgo

The blue galaxy located to the right is NGC 4536, an Intermediate Spiral Galaxy in the Virgo constellation. It is close to the celestial equator and is partly visible from both hemispheres. NGC 4536 is undergoing strong burst formation. Based on X-ray emission from the core, it may contain a small supermassive back hole. It is 50 million light-years away and has an apparent magnitude of 11.1.

 

The small galaxy closer to the centre is NGC 4533. It has a surface brightness of 23.04 mag/arcsec and is 1.82 X 0.389 arcmin.

 

The galaxy to the left is NGC 4527. It has an angular size of 6.3 X 1.3 arcmin. Its classification is an Intermediate Spiral (Hubble galaxy morphological classification), similar to the Andromeda Galaxy. It is about 48.9 million lightyears away.
