Hubble reveals a giant star-forming bubble in the Large Magellanic Cloud
Hubble has revealed a vast bubble in nebula N44, where generations of stars have reshaped clouds of gas and dust.
N44 lies in the Large Magellanic Cloud, a neighboring galaxy about 160,000 light-years from Earth.
The cavity, about 210 by 140 light-years across, was cleared as massive stars sent out powerful winds and some later exploded as supernovae.
Gas pushed to the bubble’s edge formed a dense shell, where compressed material may be collapsing to create new stars.
Hubble catalogued nearly half a million stars in the region, including nearly 30,000 young stars that have not yet begun the stable phase powered by hydrogen fusion.
Studying these stars and their surroundings can help astronomers understand how stars form and develop.
Hubble’s view of N44 shows a vast bubble in the Large Magellanic Cloud, where massive stars have cleared gas from a central region.
The cavity measures roughly 210 by 140 light-years and is surrounded by a dense, dusty shell.
The shell contains young stars, and compressed gas along the bubble’s edge may help form new generations of stars.
Hubble researchers catalogued nearly half a million stars in N44, including nearly 30,000 pre-main-sequence stars.
N44 is about 160,000 light-years from Earth.
- Who
- Researchers using the Hubble Space Telescope studied N44.
- What
- Hubble observations show a vast superbubble in a star-forming region, alongside a census of nearly half a million stars.
- When
- The article was published on November 1, 2026. The observations’ date is not stated.
- Where
- N44, in the Large Magellanic Cloud, within the constellation Dorado.
- Why
- Massive stars’ winds and supernovae cleared gas from the cavity. Compressed gas around its edges may help form new stars.
This story does not have two clearly opposing sides.
Astronomer Karl Henize catalogued individual features in N44.
Earth.com reported on the Hubble view and the star census of N44.
