What happens when a galaxy falls in with the wrong crowd? The
irregular galaxy NGC 1427A is a spectacular example of the resulting
stellar rumble. Under the gravitational grasp of a large gang of
galaxies, called the Fornax cluster, the small bluish galaxy is
plunging headlong into the group at 600 km/sec or nearly 400 mi/sec.
The galaxy was imaged by the Hubble Space Telescope’s Advanced Camera
for Surveys in January 2003.
