M74 (NGC 628) Spiral Galaxy, Rebecca Tong

M74 Galaxy

This M74 Galaxy was discovered by Pierre Méchain in September 1780 and it is in the constallation Pisces. M74 was one of the first galaxy that was discovered from "Spiral Nebula" and its' spiral arms contain clusters of blue young stars and several pinkish-red. Its' distance may be about 30 to 40 million light years as it recedes with 793 km/seonds and its spiral arms are about 1000 light years broad. It may be difficult to find M74 under the slightest light polution or other imperfect viewing conditions.

Looking at this image, I am amazed with how the color turned out because of its brightness, the center spiral becomes more yellow-ish color and its spiral arms have combination of blue and pinkish-red color in it. Its angular size is 10' and its brightness in magnitude is 10 mag. This image seems to me like a hurricane in the universe; non-destructive yet interestingly attractive. There is no doubt that galaxies and the universe reflects God's glory in so many different ways.
