Explanation: Active galaxy NGC 1275 is
the central, dominant member of the large and relatively nearby Perseus Cluster
of Galaxies. Wild-looking at visible wavelengths, the active galaxy is also a
prodigious source of x-rays and radio emission. NGC 1275 accretes matter as
entire galaxies fall into it, ultimately feeding a supermassive black hole at
the galaxy's core. This color composite image, recreated from archival Hubble
Space Telescope data, highlights the resulting galactic debris and filaments of
glowing gas, some up to 20,000 light-years long. The filaments persist in NGC
1275, even though the turmoil of galactic collisions should destroy them. What
keeps the filaments together? Observations indicate that the structures, pushed
out from the galaxy's center by the black hole's activity, are held together by
magnetic fields. Also known as Perseus A, NGC 1275 spans over 100,000 light
years and lies about 230 million light years away.
