Spiral Galaxy NGC 1566 in the Dorado - The Seyfert Galaxy NGC 1566 - NGC 1566 is a spiral galaxy located about 50 million years ago - light. Its core is very bright. It is an active galaxy called Seyfert, which probably houses a black hole in its heart. Image made with Siding Spring's 3.9m telescope. NGC 1566 is the brightest member of a nearby group of galaxies in Dorado and is at a distance of about 50 million light years. It has beautifully symmetrical, tightly - wound spiral arms, which on deep images appear to almost encircle the galaxy. This striking galaxy is also of interest because it has a very luminous nucleus which has many of the characteristics of a quasar, though it is much less energetic. Galaxies of this type are known as Seyfert galaxies, after Carl Seyfert who first recognised their peculiar nature in 1943. The active region at the centre of NGC 1566 has recently been found to vary on a timescale of less than a month, which indicates that it is extremely compact. Spe
Spiral galaxy NGC 1566 in the bream - The Seyfert Galaxy NGC 1566: NGC 1566 is a spiral galaxy located about 40 million light years ago. Its core is very bright. It is an active galaxy called Seyfert, which probably houses a black hole in its heart. Image obtained with the Hubble telescope - NGC 1566 is a galaxy located approximately 40 million light-years away in the constellation of Dorado (The Dolphinfish). NGC 1566 is an intermediate spiral galaxy, meaning that while it does not have a well defined bar-shaped region of stars at its centre - like barred spirals - it is not quite an unbarred spiral either (heic9902o). The small but extremely bright nucleus of NGC 1566 is clearly visible in this image, a telltale sign of its membership of the Seyfert class of galaxies. The centres of such galaxies are very active and luminous, emitting strong bursts of radiation and potentially harbouring supermassive black holes that are many millions of times the mass of the Sun. NGC 1566 is not jus
