This rare space phenomenon, NASA said, is known as Herbig-Haro. Especially for the object recorded by NASA, whose photo was released on Friday (3/9), the name is HH-111. It is about 1,300 light years from Earth.
—
Dr. Brad Tucker from the Australian National University explains, Herbig-Haro is also referred to as the moment of the birth of the star system.
—
“At the center you have what we call protostars — where gas from previous stars has collapsed into new baby stars,” explains Dr. Brad Tucker of the Australian National University, as quoted ABC.
—
The new object rotates rapidly and as the process occurs, it releases streams of ionized gas (gas that is so hot that all of its electrons are released) — from its north and south poles.
—
The gas then moves outward through the dust cloud in the star nursery. As it moves further, it begins to spread out in the same way a human breathes on a cold morning.
—
“As this gas spreads to the surrounding area, it begins to mix and disperse in that area and begins to create what we call bow shock (arc shock),” added Tucker. This process is clearly visible at the tip of the object.

Herbig-Haro Rare Outer Phenomenon
–
Although the birth of stars is so spectacular, the outer space objects captured by the Hubble telescope are difficult to identify. For starters, they only lasted for 10,000 – 20,000 years.
—
“It sounds like a long time, but in the astronomical scheme it’s actually a short time frame for something that exists,” explains Tucker.
—
In addition, the captured object is also not too bright because of the large amount of light that is absorbed by the dust so that it can only be seen if it is at close range. “We can’t see it in other galaxies. You only see it in the Milky Way,” he said.

Launched 31 years ago, the Hubble telescope’s lifetime is coming to an end. What’s more, he’s been having some technical problems lately.
—
Its successor, the James Webb telescope, will only launch in November or December 2021. It will have a greater infrared capacity than Hubble, but not as visually as its predecessor.
—
This means that images of objects like HH-111 will look different than those captured by the Hubble telescope, with more detail in the dust cloud but less visual definition.
