Nebula N11: Billowing Bubbles of Stellar Floss in Dorado | Hubble

This Hubble image shows a complex cluster of emission nebulae, nestled within the Large Magellanic Cloud.

This inset image shows where N11 is located within the Large Magellanic Cloud.

Here is a bubbling region of stars old and new. It lies around 160,000 light-years away in the constellation Dorado. This complex cluster of emission nebulae, known as N11, was discovered by American astronomer and NASA astronaut Karl G. Henize in 1956. NASA’s Hubble Space Telescope captured this image of the cluster in the Large Magellanic Cloud (LMC), a nearby dwarf galaxy orbiting the Milky Way.

This region is named LHA 120-N 11, informally known as N11, and is one of the most active star formation regions in the nearby Universe. 

About 1,000 light-years across, N11’s sprawling filaments weave stellar matter in and out of each other like sparkling candy floss. These cotton-spun clouds of gas are ionized by a burgeoning host of young and massive stars, giving the complex a cherry-pink appearance. Throughout N11, colossal cavities burst from the fog. These bubbles formed as a result of the vigorous emergence and death of stars contained in the nebulae. Their stellar winds and supernovae carved the surrounding area into shells of gas and dust.

N11’s stellar activity caught the attention of many astronomers. It is one of the largest and most energetic regions in the LMC. To investigate the distribution of stars in N11, scientists used Hubble’s Advanced Camera for Surveys, taking advantage of its sensitivity and excellent wide-field resolution. The cluster houses a wide array of stars for Hubble to examine, including one area that has stopped forming stars, and another that continues to form them. Hubble’s unique capabilities allowed astronomers to comprehensively study the diversity of stars in the N11 complex, and map the differences between each region.

Image 1 Description: Glowing clouds of pink and red gas and dust fill the image, along with several stars—foreground stars shine with diffraction spikes, and more distant stars fill the background.

Image 2 Description: The bottom half of the image shows N11. Glowing clouds of pink and red gas and dust fill the image, along with several stars—foreground stars shine with diffraction spikes, and more distant stars fill the background. Above it to the right, a smaller image shows a starry region of space with orange tendrils of gas and dust with a white rectangle designating the portion that shows N11. To its left, another small image shows a wide view of a diffuse galaxy with a white rectangle designating the portion that shows N11.
