A spectacular new image from the Hubble Space Telescope reveals a vast cloud of glowing gas, dark dust and brilliant young stars in one of the Milky Way’s closest neighbouring galaxies.

The image, released by ESA/Hubble on September 3, 2026, shows LHA 120-N44, commonly known as N44, a massive star-forming nebula located in the Large Magellanic Cloud (LMC), about 160,000 light-years from Earth.

A Giant Bubble in Space

One of the most striking features of N44 is an enormous empty-looking region at its centre.

This structure is known as a superbubble, stretching approximately 210 by 140 light-years across. It was created by powerful stellar winds and supernova explosions from massive stars at the heart of the region.

Over time, these energetic events pushed away much of the gas surrounding the stars, carving out the enormous cavity we see today. The displaced material collected around the cavity, forming a dense shell of gas and dust.

But this cosmic bubble is far from empty.

A Stellar Nursery Inside a Stellar Battlefield

The shell surrounding N44 is being illuminated by intense ultraviolet radiation from massive stars. The radiation causes the gas to glow, revealing intricate structures throughout the nebula.

Even more remarkably, new stars are forming inside the compressed shell of gas.

This makes N44 an important natural laboratory for astronomers trying to understand how stars are born.

Astronomers want to determine how long it takes for cold clouds of gas to collapse into dense clumps and eventually form stars whose cores become hot enough for nuclear fusion to begin.

Nearly 30,000 Stellar Babies

Hubble’s observations of N44 provide an extraordinary look at the region’s stellar population.

Researchers surveyed nearly half a million stars in the area, including stars belonging to the cluster as well as unrelated stars lying in front of it.

Among them were almost 30,000 pre-main-sequence stars — extremely young stars that have not yet started fusing hydrogen into helium in their cores.

These young stars are particularly valuable to scientists because they provide clues about the earliest stages of stellar evolution.

Hubble’s sharp vision and sensitivity allow astronomers to distinguish these faint young stars even within the incredibly crowded environment of a stellar nursery.

Another Bubble Hides in the Image

N44 contains several smaller structures within its enormous star-forming complex.

One of them, called N44F, can be seen near the upper-right portion of the image. Unlike the enormous superbubble, N44F was created by the powerful stellar winds of a single hot, massive star.

Those winds have sculpted the surrounding gas, creating pillars and other dramatic structures within the nebula.

It is a striking example of how individual stars can reshape their surroundings.

Why N44 Matters

The Large Magellanic Cloud is particularly useful to astronomers because it is relatively close to the Milky Way while also having fewer elements heavier than helium than our galaxy.

Studying star formation in this environment can therefore provide insights into how stars may have formed in galaxies that existed much earlier in the history of the Universe.

Hubble’s observations of the lowest-mass young stars in N44 are helping researchers investigate how long star formation takes and what masses newborn stars typically have.

A Cosmic Bubble Shaped by Stars

N44 is a beautiful reminder that stars do not simply form inside galaxies — they can dramatically transform their surroundings.

Powerful stellar winds and supernova explosions have carved an enormous cavity through the nebula, while the material pushed outward has become a new environment for future generations of stars.

In this single region, astronomers can see stellar birth, stellar evolution and the destruction caused by massive stars happening together.

What looks like a beautiful cosmic cloud is actually an enormous, dynamic ecosystem stretching across hundreds of light-years.

The Universe is constantly recycling its material — and N44 gives us a front-row view of that process.
