NGC 6744 (also known as
Caldwell 101 or the
Pavo Galaxy=10.5px ) is an
intermediate spiral galaxy in the
constellationPavo (Peacock). Its velocity with respect to the
cosmic microwave background is 802 ± 3 km/s, which corresponds to a
Hubble distance of 38.6 ± 2.7
Mly (11.82 ± 0.83
Mpc).=10.5px However, 21
non redshift measurements give a distance of 23.63 ± 1.68 Mly (7.244 ± 0.514 Mpc).=10.5px It was discovered on 30 June 1826 by Scottish astronomer
James Dunlop, observing from
Parramatta, Australia.NGC 6744 is considered as a
Milky Way mimic in the immediate vicinity, displaying flocculent (fluffy) arms and an elongated core.=10.5px It also has at least one distorted companion galaxy (NGC 6744A) superficially similar to one of the
Magellanic Clouds.NGC 6744 is a
LINER galaxy, i.e. its nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.=10.5px Also, the galaxy has an
active galactic nucleus (AGN) of low luminosity.NGC 6744 lies within the
Virgo Supercluster.
Two
supernovae have been observed in NGC 6744. R. Martin and Berto Monard discovered SN 2005at (
type Ic, mag. 16) on 15 March 2005.=10.5px
BlackGEM discovered another
astronomical transient, designated SN 2024vjm, on 13 September 2024. After initial
Spectral analysis, the star was classified as a
peculiarnova, but further observations showed the object to be a faint
type Iax supernova, likely the closest known of this type.
