The galaxy’s orientation is nearly frontal, making it one of the best barred spirals observable from the Northern Hemisphere. NGC 7479 (also known as Caldwell 4) is a barred spiral galaxy about 105 million light years away in the constellation Pegasus. NGC 7479 (also known as Caldwell 4) is a barred spiral galaxy about 105 million light years away in the constellation Pegasus. The image below is an image of NGC 7479 from the Digitized Sky Survey 2 (DSS2 – see imprint), taken in the red channel.
NGC 7479 is a barred spiral galaxy about 105 million light years away in the constellation Pegasus. Wikipedia NGC 7479 was first discovered by William Herschel in 1784 and is a classical barred spiral galaxy.
What type of galaxy is NGC 7479?
The spiral structure is also unusual in that the arms appear to rotate in the opposite direction to those in the visible and near IR when observed in the radio spectrum. However, the galaxy, which is also known as the Propeller Galaxy, has some unusual features in that one of the spiral arms is much more prominent than the other. The following image is of NGC 7479 from the Digitised Sky Survey 2 (DSS2 – see imprint), taken in the red channel.
What is NCG in the Milky Way Galaxy?
This image was taken with Hubble’s Wide Field Camera 3 (WFC), which is extremely sensitive to visible and infrared light. It emphasised that there may be even larger spiral galaxies than NGC 6872 that are still waiting to be discovered and studied in depth. With a radius of 26,000 light years, it is about twice the size of the bars of nearby spirals, the researchers said. Its distance from Earth is about 25.2 million light-years, or 7.72 megaparsecs, similar to the distance of M101 (NGC 545 in the constellation Ursa Major).
NGC 6946, sometimes called the Fireworks Galaxy, is an intermediate spiral galaxy with a small bright core whose position in the sky straddles the boundary between the northern constellations of Cepheus and Cygnus.
