The blue clusters in the picture are Herbigger-Haro objects numbered from 7 to 11 (HH 7-11), located in NGC 1333, a reflective Nebula filled with dust and gas, about 1,000 light-years from our planet.

NASA wrote in its tweet:

The Hubble Telescope has captured conclusive evidence of a new star! The five celestial bodies are located within NGC 1333, in the blue region above the image center. NGC 1333 is a reflection nebula filled with gas and dust, about 1,000 light-years away from Earth.

Herbig-Haro celestial bodies are temporary astronomical phenomena near newborn stars. They leave the star that created them at 150,000 miles an hour and will disappear into the universe in tens of thousands of years.

According to NASA, the young star, the source of these Herbieg-Haro objects, is called SVS13. In the image, the bright blue cluster is moving away from SVS 13 to the upper left. The distance from HH 7 to SVS 13 is about 20,000 times the distance from the sun to the earth.

The formation of Herbigger-Harrow objects has undergone a complex process: a young star ejects ionized gas, which collides with nearby dust and gas clouds at high speeds, leading to the formation of these strange bright blue clusters in the depths of the universe. (Author/Liangbi)
