Description:
NGC 7535 (left) and NGC 7538 (right) are star-forming nebulae that straddle the Cassiopeia - Cepheus border. NGC 7635 is commonly known as the Bubble Nebula. The bubble is formed from hot stellar winds from a star that is 45 times more massive than our Sun. Outflow from the star pushes cold interstellar material away at a velocity exceeding 4 million miles per hour to form the perimeter of the bubble. The bubble is about 7 light-years in size and 7000 light-years away from Earth. NGC 7538 is an emission and reflection nebula that is home to the largest known protostar. The European Space Agency's Herschel Space Observatory "identified 13 massive, dense clumps where colossal stars could form in the future" according to Cassandra Fallscheer, lead author of a paper published in The Astrophysical Journal, as well as a strange ring of stellar seeds which may be the edge of a bubble carved by previous stellar explosions. NGC 7538 is about 9000 light-years away from Earth. This image is an Ha/OIII/RGB taken with a Takahashi FSQ106ED. Data from a C14 Edge were used to supplement detail in the cores of the nebulae Online references used in the description: https://hubblesite.o...3725-Image.html https://en.wikipedia.org/wiki/NGC_7635 https://www.esa.int/...actory_NGC_7538 https://www.nasa.gov...rschel/pia18452 https://en.wikipedia.org/wiki/NGC_7538 https://www.universe...nside-ngc-7538/
