They are held together by a weak gravitational attraction, which is why this cluster has an irregular shape.
The Hubble Space Telescope captured this image of the open star cluster NGC 1858 in a satellite galaxy of the Milky Way, which is about 160,000 light-years from Earth and contains several massive stars that shine brightly in the center of the image. Space writes about it.
Note that NGC 1858 is an open star cluster. That is, the stars in it are bound together by a weak gravitational attraction, so it has an irregular shape.
In addition, scientists say that this section of space is an emission nebula. It is a cloud of interstellar gas ionized by ultraviolet radiation from nearby stars.
“The gas of the nebula emits its own light, visible as a dark cloud filling the center and lower right of the image. In this region of the galaxy, there are either areas where the formation of new stars, and there are those where it is still ongoing. In general, in the Large Magellanic Cloud , which is a satellite galaxy of our galaxy, you can find a large number of regions where active star formation is taking place. The NGC 1858 is a region,” experts said.
Astronomers say most of the stars in the foreground are young. They are 10 million years old. Stars are in different stages of their evolution.
Moreover, NGC 1858 has a protostar. That is, a very young, forming star.

We remind you, Hubble first took a stunning picture of a dwarf galaxy with a strange shape. A celestial body called NGC 1156 is located 25 million light-years from Earth in the constellation Aries.
