Godzilla Nebula Imaged By Spitzer (25 October 2021)

This colorful image shows a nebula – a cloud of gas and dust in space – captured by NASA's now-retired Spitzer Space Telescope located is in the constellation Sagittarius, along the plane of the Milky Way, which was as part of Spitzer's GLIMPSE Survey (short for Galactic Legacy Infrared Mid-Plane Survey Extraordinaire). With a little imagination, you might be able to see the outlines of Godzilla. Stars in the upper right (where this cosmic Godzilla's eyes and snout would be) are an unknown distance from Earth but within our galaxy. Located about 7,800 light-years from Earth, the bright region in the lower left (Godzilla's right hand) is known as W33. When viewed in visible light, this region is almost entirely obscured by dust clouds. But infrared light (wavelengths longer than what our eyes can perceive) can penetrate the clouds, revealing hidden regions like this one. Blue, cyan, green, and red are used to represent different wavelengths of infrared light; yellow and white are combinations of those wavelengths. Blue and cyan represent wavelengths primarily emitted by stars; dust and organic molecules called hydrocarbons appear green; and warm dust that's been heated by stars or supernovae (exploding stars) appears red. When massive stars die and explode into supernovae, they reshape the regions around them, carving them into different shapes; they also push material together and initiate the birth of new stars that continue the cycle. https://photojournal.jpl.nasa.gov/catalog/PIA24579
