Spiral Galaxy NGC 7814

Ghost of Jupiter

NGC 7814 is a spiral galaxy that is seen edge on from the Earth. Spiral galaxies are characterized by their distinct spiral shape. Within the spiral, the central bulge has more densely packed older stars, while the arms of spiral typically contain younger stars and clouds of gas from which the young stars are born. This specific galaxy was discovered in 1784 by Friedrich Wilhelm Herschel. While its true distance is still unknown several sources estimate its distance to be between 40 and 50 million light years away.

In this specific image the two most notable aspects are the bright central bulge of the galaxy and the narrow dark corridor that runs through the major axis of the galaxy. This dark band is a dust lane that runs across this edge of the galaxy. As would be expected the central bulge is much brighter indicating the close packing of the stars while the edges are more faint indicating the greater space between stars. In the larger linked image a second background galaxy is also visible to the upper left of NGC 7814. In this image NGC 7814 has a maximum angular size of about 144 arc seconds. This means it has a linear size of 9.91 E11 meters, roughly 99 million kilometers or 31,416 light years.
