NASA has actually launched a stunning close-up shot of NGC 6951, a disallowed spiral nebula caught by the NASA/ESA Hubble Space Telescope.
This Hubble image reveals NGC 6951, a disallowed spiral nebula some 70 million light-years away in the constellation of Cepheus. The color image was made from different direct exposures taken in the noticeable and near-infrared areas of the spectrum with Hubble’s Advanced Camera for Surveys( ACS ). 2 filters were utilized to sample numerous wavelengths. The color arises from designating various colors to each monochromatic image connected with a private filter. Image credit: NASA/ ESA/ Hubble/ L.C. Ho/ G. Brammer/ A. Filippenko/ C. Kilpatrick.
NGC 6951 lies around 70 million light-years far from Earth in the constellation of Cepheus.
Catalogued as NGC 6952, LEDA 65086, IRAS 20366 +6555, and UGC 11604, the galaxy is about 75,000 light-years throughout.
NGC 6951 was found individually by the French astronomer Jerome Coggia in 1877 and the American astronomer Lewis Swift in 1878.
Astronomers categorize it as a disallowed spiral nebula, a Type II Seyfert galaxy, and a low-ionization nuclear emission-line area (LINER) galaxy.
“As this Hubble image reveals, NGC 6951 is a spiral nebula with a lot of interesting structures,” the Hubble astronomers stated in a declaration.
“Most distinctive are its spiral arms, which are dotted with dazzling red nebulae, intense blue stars and filamentary dust clouds.”
“The spiral arms loop around the stellar center, which has a golden radiance that originates from a population of older stars.”
“The center of the galaxy is likewise clearly lengthened, exposing the existence of a gradually turning bar of stars.”
At the center of NGC 6951 lies a supermassive great void surrounded by a so-called circumnuclear ring.
“NGC 6951’s bar might be accountable for another exceptional function: a white-blue ring that confines the very heart of the galaxy,” the astronomers stated.
“This is called a circumnuclear starburst ring– basically, a circle of improved star development around the nucleus of a galaxy.”
“The bar funnels gas towards the center of the galaxy, where it gathers in a ring about 3,800 light-years throughout.”
“Two dark dust lanes that run parallel to the bar mark the points where gas from the bar goes into the ring.”
“The thick gas of a circumnuclear starburst ring is the ideal environment to produce an outstanding variety of stars.”
Utilizing the Hubble information, astronomers recognized more than 80 prospective star clusters within NGC 6951’s ring.
“Many of the stars formed less than 100 million years earlier, however the ring itself is longer-lived, possibly having actually existed for 1-1.5 billion years,” the scientists discussed.
