Bursts
of pink and red, dark lanes of mottled cosmic dust, and a bright
scattering of stars — this NASA/ESA Hubble Space Telescope image shows
part of a messy barred spiral galaxy known as NGC 428. It lies
approximately 48 million light-years away from Earth in the
constellation of Cetus (The Sea Monster).
Although a spiral shape is still just about visible in this close-up
shot, overall NGC 428’s spiral structure appears to be quite distorted
and warped, thought to be a result of a collision between two galaxies.
There also appears to be a substantial amount of star formation
occurring within NGC 428 — another telltale sign of a merger. When
galaxies collide their clouds of gas can merge, creating intense shocks
and hot pockets of gas, and often triggering new waves of star
formation.
NGC 428 was discovered by William Herschel in December 1786. More
recently a type of supernova designated SN2013ct was discovered within
the galaxy by Stuart Parker of the BOSS (Backyard Observatory Supernova
Search) project in Australia and New Zealand, although it is
unfortunately not visible in this image.
This image was captured by Hubble’s Advanced Camera for Surveys (ACS)
and Wide Field and Planetary Camera 2 (WFPC2).
