N44

▲ ▼

description N44 Overview

N44 is an expansive emission nebula and H II region located within the Large Magellanic Cloud, a satellite galaxy of the Milky Way. It features a prominent superbubble, a massive cavity carved out by the intense stellar winds and supernova explosions of massive young stars at its center. The complex also contains smaller bright nebulosity and dark dust structures. N44 is frequently studied by astronomers observing the process of star formation and the dynamics of superbubble evolution in neighboring galaxies.

help N44 FAQ

Where is the N44 superbubble located?

N44 lies in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. It appears in the constellation Dorado and is roughly 160,000 light-years from Earth.

What created the large cavity inside N44?

Winds from massive young stars cleared gas from the central region, while supernova explosions added further energy. Together these processes produced the expanding shell commonly described as a superbubble.

Why does N44 glow red in many astronomical images?

Ultraviolet radiation from hot stars ionizes the surrounding hydrogen gas. When the hydrogen recombines, it emits strongly at the red hydrogen-alpha wavelength used in many observatory images.

Is N44 one nebula or a larger star-forming complex?

N44 is a complex containing ionized gas, dark dust, stellar associations and multiple shells rather than a single uniform cloud. New stars are forming along some compressed edges of its central cavity.
