Spiral galaxy NGC 7331
Spiral galaxy NGC 7331. Spitzer Space Telescope infrared image of the spiral galaxy NGC 7331. This galaxy lies around 50 million light years from Earth in the constellation Pegasus. Notable in this image is the bright yellow ring of star formation around the galaxys centre. The ring has a radius of 20, 000 light years and is made up of polycyclic aromatic hydrocarbons (PAHs), with enough material to form about four billion stars of the magnitude of our Sun. The three galaxies below NGC 7331 are about 10 times farther away. Wavelengths of 3.6 microns are coloured blue, 4.5 microns are green, 5.8 microns are yellow and 8.0 micron wavelengths are red

EDITORS COMMENTS
This print showcases the mesmerizing Spiral galaxy NGC 7331, captured by the Spitzer Space Telescope in infrared. Located approximately 50 million light years away from Earth in the constellation Pegasus, this celestial beauty never fails to astound with its intricate details. The most striking feature of this image is the luminous yellow ring encircling the center of the galaxy. Spanning an impressive radius of 20,000 light years, this ring is composed of polycyclic aromatic hydrocarbons (PAHs), which possess enough material to birth around four billion stars akin to our Sun. It serves as a stellar nursery where new life emerges amidst cosmic wonder. Adding further depth to this awe-inspiring scene are three galaxies positioned below NGC 7331. These distant galaxies are situated nearly ten times farther away than their prominent neighbor, accentuating the vastness and grandeur of our universe. To enhance clarity and comprehension, different wavelengths have been assigned colors: blue represents 3.6 microns, green signifies 4.5 microns, yellow corresponds to 5.8 microns, and red symbolizes 8.0 micron wavelengths. This remarkable photograph not only captivates with its vibrant hues but also offers a glimpse into the enigmatic world beyond our own. Its portrayal of spiraling beauty and celestial phenomena ignites curiosity about our place in the cosmos while reminding us that there is still so much left for humanity to explore and understand.
