The massive star on the far outskirts of our Milky Way shows that the powerful cosmic blowing in the new image is blowing, agreeing with James Webb Webb Space Telescope almost an infrared camera.
James Webbo’s Space Telescope (JWST) caught two nozzles, struck by the surrounding interstellar medium, forming a vague structure called the Sharpless 2-284 or SH2-284. Jets extends a total of eight light -years as they expand hundreds of thousands of miles per hour. In addition, their existence is proof of the process of mass stars of the universe.
“When we found a huge star launching these nozzles, we realized that we could use Webb’s observations to check the theories of mass star formation,” said Jonathan Tan of the University of Virginia, Charlottesville and Chalmers University of Technology.
Lower mass stars often see stars nozzles as those stars are formed. The nozzles promote substances, mainly hydrogen gas, falling on a growing star. This material is twisted into a disc around a young protostar. Part of the disk material is absorbed by the star by increasing its mass, but if too much material is stacked by the disk, some excess excess excess is rejected firmly wrapped in magnetic fields, which emit material with two nozzles along the young star axis.
Small mass stars are formed quite neatly, but one theory of mass star formation theory-star species that go supernova-is that their filling gas accumulation is more chaotic. If that were the case, it will cause the star and its accumulation disc, and the nozzles move, rotate and spray over the area.
However, the JWST image from the SH2-284 does not show any evidence that the jet airplanes were moving when they are straight and directed almost 180 degrees in front of each other. This means that the star formation was not chaotic.
Star forming models indicate the size of the nozzles scales, the size of which makes them.
“These models mean that the star is approximately ten times larger than the solar mass and is still growing and feeding on this leak,” Tan said.
How energetic these nozzles are, how straight, how narrowly collated and their age can help astronomers better understand the environment in which stars receiving those nozzles and the inner properties of such stars.
“We really didn’t know that before the observation was a huge star with such a super Jeet,” Yu Cheng, the National Astronomical Astronomical Astronomical Observatory, said. “Such an impressive leakage of molecular hydrogen from the mass star is rare in our other regions of the galaxy.”
Cheng mentions the SH2-284 place in our galaxy. This young star is 15,000 light -years from the Earth, located on the outskirts of the milk road spiral disc itself, where the abundance of elements is heavier than hydrogen and helium. This is because such elements are formed in the stars, and the formation of the stars on the edge of the galaxy simply was not vibrant enough to create many of these elements, and astronomers (a little confusing) call “metals” even if not all metals in the traditional sense.
However, astronomers are lucky enough to find a star forming this low metal environment, as these conditions mimic those found in the early universe.
“Our discovery explains the mechanism of mass star formation in a low metal environment, so we can use this huge star as a laboratory to investigate what happened in previous space history,” he said.
The latest is the story of the SH2-284. Jets tips are the oldest and the young star’s life was chronized for long jet aircraft.
“Initially material [in the tips] It was close to the star, but for over 100,000 years, the tips spread, and then the items are for younger leaks, ”said Tan.
The growing star is not visible directly. Bright stars with diffraction spikes are closer to our foreground. However, JWST can choose the SH2-284 structure with threads, knots, bows shots and linear circuits from the caterpillar material resulting from the interaction of the nozzles with the surrounding interstellar medium.

However, as powerful, as these nozzles and the discomfort they create, they are only temporary. After all, the star will fall out of her cocoon, completely grown, perhaps dozens of times our solar mass. Its life will be limited to several million years. It will then explode, creating a whole new Ukula, one of the stars’ death, not birth, but his legacy will enrich the space with the metals he falsified.
And the star cycle will continue.
