The science

NGC 6744 is an intermediate spiral galaxy in the constellation Pavo (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). However, 21 non redshift measurements give a distance of 23.63 ± 1.68 Mly (7.244 ± 0.514 Mpc). It was discovered on 30 June 1826 by Scottish astronomer James Dunlop, observing from Parramatta, Australia. It has a mass of 5.92×1010 M☉.
