A new snapshot of a busy star cluster Hubble Space Telescope The Observatory that proves the legend still knows, even in the Golden Age James Webb Space Telescope.
This figure shows the most detailed view of NGC 346, a stellar nursery in a small wheat cloud, a dwarf’s Milky Way Milky Way About 210,000 Light Years In Tukana constellation. Although clusters have been observed in the past, this is the first data for all three light wavelengths (infrared, visible and ultraviolet). The result is a spectacular portrait of how stars form and affect their surroundings space.
But this Glowing newborn cradle It also provides clues to astronomers about how young Whippersnappers in our universe look like.
“The element of the small wheat slurry cloud is not as heavy as helium,” the European Space Agency said. NASA. “This makes the conditions in galaxies similar to those that existed in the early universe.”

The cluster is filled with more than 2500 new stars, and these stars are Hubble ImagesIn the Milky Way, there are much less heavy chemicals than in the Milky Way. It is made mainly from hydrogen and helium. So scientists use it as a case study to show the formation of stars billions of years ago.
Mixable light speed
Stellar cores are considered elemental factories: for example, they make carbon form the same chemicals Humans and many life on Earth is based. Then, through supernova explosions, they spread these heavier elements, such as calcium in bones and calcium found in iron in transstellar space. This dispersed seed A new generation of stars and planets.
Given that most chemicals in the universe come from Exploding starsscientists have reasonably believed that the eldest son must be composed of hydrogen and helium Original material from big Bang. As time passes, the stars die and scatter the heavier elements, the subsequent stars form more diverse and complex components.
Around the clusters in the Hubble image is a luminous pink cloud called a nebula, where hot stars emit ultraviolet rays, illuminating the surrounding hydrogen. These bright areas are short-lived-as long as Gigundo wins momentum, only sparkles. Astronomers say big stars can only last for millions of years, which only holds a place in the universe for 13.8 billion years.
Snakelike’s thick dust clouds are the remaining of the original star-making materials that have not been pushed away by the growing stars. Huge stars, sunable to do this with strong radiation and strong stellar winds (charged particle flow).
Scientists recently used Hubble’s powerful infrared peer Webb Investigate 10 stars in the same cluster. They found that even at the relatively old age of stars, they still kept a lot of disks, and the surrounding clouds of gas and dust could eventually combine to form a baby world.
The previous idea was that these original stars would soon lose their lightweight disks very quickly. Study person in charge Guido de Marchi is only two to three million years old.
“This also means that the planets have more time to form and grow around these stars,” De Marchi said.
