A spectacular spiral galaxy is being studied by the Hubble telescope.

The NGC 1961 galaxy, located in the constellation Camelopardalis, about 200 million light-years from Earth, is a spiral galaxy with curved arms. Taken by NASA’s Hubble Space Telescope, the image shows the grand spiral arms unfolding, the bright, blue regions of bright young stars reflecting the dusty spiral arms swirling around the bright center of the galaxy.

Astronomers have followed two proposals to produce this image, the first being to study the unpublished Arp galaxies, and the second to look at the progenitors and explosions of various types of supernovae. NGC 1961 is an intermediate spiral and an AGN, or active galactic nucleus, type galaxy, the AGN being a narrow region at the center of the galaxy with exceptional luminosity, but NGC 1961 has a fairly common type of AGN, which emits less energy-charged particles.

NGC 1961 The galaxy has become distorted, yet no companion has been observed, suggesting that NGC 1961 has merged with another double nucleus. AGN galaxies have very bright centers, and they often outshine the rest of the galaxy at certain wavelengths of light, astronomers say, suggesting that these galaxies are most likely to have supermassive black holes at their cores, and that may be responsible for their evolution, The bright jets that shape it and the winds are churning.
