This worth posting simply because it’s pretty.
NGC 6814 is an intermediate spiral galaxy in constellation Aquila located about 75 million light years from Earth. It’s a Seyfert galaxy with an extremely bright nucleus powered by a supermassive black hole with roughly 10 millions times the mass of the Sun. The galaxy is also a highly variable source of X-ray radiation. UV and optical emission also vary, although more smoothly, with time lag of two days behind the x-ray output.
