NGC 7674 is a barred spiral galaxy in the constellation Pegasus, known as Markarian 533, and is the brightest member of the Hickson 96 compact galaxy group. It's about 350-400 million light-years away and features tidal streams from interactions with companions, a central bar, and a powerful active nucleus (Type 2 Seyfert) that likely hosts a binary supermassive black hole system.
Type: Barred spiral galaxy, Seyfert 2 galaxy, luminous infrared galaxy.
Location: Constellation Pegasus.
Distance: Approximately 350-400 million light-years.
Size: About 125,000 light-years across.
Group: Brightest member of the Hickson 96 compact group.
A central bar-shaped structure.
Long, faint tidal streamers caused by gravitational interactions with companion galaxies.
A powerful active galactic nucleus (AGN).
