Cosmic bubbles in the Milky Way! 🌌
This Spitzer Space Telescope image shows a cloud of dust and gas filled with bubbles 10 to 30 light-years across, each containing hundreds of thousands of stars.
This active region of star formation is located within the Milky Way galaxy, in the constellation Aquila (also known as the Eagle). Black veins running throughout the cloud are regions of especially dense cold dust and gas where even more new stars are likely to form.
The colors in this image represent different wavelengths of infrared light. Blue represents a wavelength of light primarily emitted by stars; dust and organic molecules called hydrocarbons appear green, and warm dust that's been heated by stars appears red.
