Messier 49 (also known as M49 or NGC 4472) is a giant elliptical galaxy about 56 million light-years away in the equatorial constellation of Virgo.

From the detected radio emission, the core region has roughly 1053 erg (1046 J or 1022 YJ) of synchrotron energy.

[4][b] X-ray emissions shows a structure to the north of Messier 49 that resembles a bow shock.

To the southwest of the core, the luminous outline of the galaxy can be traced out to a distance of 260 kpc.

[5] The dwarf shows a trail of debris spanning roughly 1 × 5 arcminutes, which corresponds to a physical dimension of 6 × 30 kpc.
