The Hubble Space Telescope has captured a stunning new image of NGC 346, a young star cluster in the Small Magellanic Cloud. This satellite galaxy of the Milky Way lies 200,000 light-years away in the constellation Tucana. The image showcases more than 2,500 newborn stars within NGC 346.
The cluster’s most massive stars emit an intense blue light, illuminating the surrounding glowing pink nebula and snakelike dark clouds. Hubble’s sensitivity and resolution have allowed researchers to study the star formation in NGC 346 in great detail. By comparing observations taken 11 years apart, they discovered that the cluster’s stars are spiraling inward towards the center.
This motion is influenced by a stream of gas outside the cluster that fuels star formation at its core.
Hubble captures NGC 346’s vibrant stars
The Small Magellanic Cloud has a lower abundance of elements heavier than helium than the Milky Way.
This makes its conditions similar to those in the early universe, providing valuable insights into the early stages of cosmic evolution. NGC 346’s hot, massive stars produce intense radiation and stellar winds that shape the surrounding nebula, named N66. As the brightest example of an H II region in the Small Magellanic Cloud, N66 is set aglow by the ultraviolet light from the young stars.
These regions only shine for a few million years, indicating the cluster’s youth. The Hubble Space Telescope, a project of international cooperation between NASA and ESA, continues to advance our understanding of the universe after more than three decades of operation. This new image of NGC 346 is part of a series revisiting stunning Hubble targets with updated data and processing techniques, creating even more detailed views of these cosmic wonders.
