NGC 6744, a Milky Way-like spiral galaxy
Tags: galaxy, spiral, AAT
This beautiful galaxy is about 25 million light years away in the
direction of Pavo, a constellation of the southern hemisphere winter.
It sits in a rich starfield, and is strongly inclined to our line of
sight. NGC 6744 is believed to one of the most Milky Way-like of all
the nearby spirals, with fluffy (flocculent) spiral arms and a large
and distinctly elongated nucleus. It also has other similarities to the
Milky Way that are not visible here (but seen on a deep image
) with at least one
distorted companion galaxy superficially similar to one of the
The CCD chip that made this picture at the prime focus of the AAT
covers about 7 arc minutes of sky. But the galaxy has a much bigger
angular size than this, so a series of four overlapping exposures were
made in red, green and blue light. Each 3-color set was made into a
color picture and the four images merged to produce the (almost)
seamless image seen here.
