Classifications and Characteristics of NGC 6951.
Astronomers often classify NGC 6951 as a Type II Seyfert galaxy, a type of active galaxy that produces large amounts of infrared radiation and has slow-moving gaseous matter near its. Some astronomers classify NGC 6951 as a low-ionization nuclear emission-line region (LINER) galaxy, which resembles a Type II Seyfert galaxy but with a cooler nucleus that gives off weakly ionized or neutral atoms like sulfur, nitrogen, and oxygen. The entire galaxy has to do with 75,000 light-years across, and since it is close to the northern celestial pole, it is visible from the northern hemisphere.
The Heart of the Galaxy and Its Supernova Events.
Researchers hypothesize that interstellar gas flows through the thick, starry bar of the galaxy to the circumnuclear ring, which supplies brand-new material for star formation. Spiral lanes of dust, shown in dark orange, connect the center of the galaxy to its external regions, contributing more product for future star development.
Some of the stars in NGC 6951 have also knowledgeable fantastic excellent explosions known as supernovae; astronomers have counted as many as six supernovae in this galaxy in the previous 25 years. Researchers continue to study NGC 6951 to much better comprehend the environments that produce supernovae.
The galaxy had its greatest rates of star formation about 800 million years ago, then sat silently for 300 million years before starting to birth stars again. Astronomers often categorize NGC 6951 as a Type II Seyfert galaxy, a type of active galaxy that gives off big quantities of infrared radiation and has slow-moving gaseous matter near its. Some astronomers categorize NGC 6951 as a low-ionization nuclear emission-line region (LINER) galaxy, which is comparable to a Type II Seyfert galaxy but with a cooler nucleus that releases weakly ionized or neutral atoms like nitrogen, sulfur, and oxygen. Some of the stars in NGC 6951 have likewise experienced great outstanding explosions understood as supernovae; astronomers have counted as many as six supernovae in this galaxy in the past 25 years.

NASAs Hubble Space Telescope has caught this comprehensive picture of NGC 6951, a significant galaxy in the Cepheus constellation. Prominent for its star formation history, distinct categories, and several supernovae events, this galaxy uses astronomers valuable insights into the universes operations.
Bright blue spiral arms twist around the luminescent white center of this starry galaxy. This brand-new NASA Hubble Space Telescope image includes NGC 6951, an intermediate spiral galaxy 78 million light-years away in the Cepheus constellation.
The galaxy had its highest rates of star development about 800 million years back, then sat silently for 300 million years before starting to birth stars again. The typical age of a star cluster, or gravitationally-bound group of stars, in this galaxy is 200 to 300 million years old, though some are as old as one billion years.
