NGC 7727 - Clash of the
Titans
While the movie Clash
of the Titans may be an epic thriller, nothing compares to the
immensity, intrigue, and beauty when two of the most titanic
objects known to exist, clash. NGC 7727 is not a single galaxy,
but two separate (likely spiral) galaxies that are nearing the
final process of merging into one larger galaxy after a billions
year clash. Look closely and you can even trace the path the
galactic nuclei took starting from lower left and circling each
other five to six countable times in this image. A close up
image below also clearly shows two bright points of light near
the center. The bringer one is certainly the center of the
larger original galaxy. The fainter may well be the second
nuclei or merely a foreground star. At the center of each these
two nuclei is a super massive black hole containing millions of
stellar masses each compressed into an infinitesimally small
point. These black holes will circle each other for many
millions of years before combining masses. The final appearance
of the galaxy is still not well predicted but it is likely to be
an elliptical galaxy mostly devoid of spiral arms or dust lanes
necessary for new star formation. Stats for this galaxy are as
follows: RA: 23h 39m 53.5s, Dec: -12° 17' 38", Mag: 11.5 (B),
Size: 4.7'x3.5', Class: SAB(s)a pec.
