These stars live in their own bubbles 🫧⁣ ⁣ A cloud of gas and dust full of bubbles is captured in this image from our Spitzer Space Telescope. Each bubble is filled with hundreds to thousands of young, massive stars which inflate dense clouds of gas and dust.⁣ ⁣ Flows of particles emitted by the stars, called stellar winds, as well as a the light stars produce, can push the surrounding material outward, creating the distinct perimeter of the bubbles. The bubbles are estimated to be 10 to 30 light-years across, based on what astronomers know about them and other cosmic bubbles.⁣ ⁣ Image description: ⁣ 1-2. Two cloudy nebulae appear, each in shades of green, yellow and red. One appears to blast across the image from the lower left just about to the top of the image just the right of center. At the top end the nebula had a bright white spot with a red halo, and trailing behind to the lower left of the image is a semi-transparent green cloud looking like a dress trailing behind. Taking...
