NASA has released an unprecedented image of the flow of matter produced by a young star, captured by the James Webb telescope. According to information from the space agency, the star is a kind of childhood analogue of our Sun.
The star has about 8% of the current mass of the Sun, but, one day, it should transform into a celestial body similar to this one.
According to NASA, luminous regions like the one recorded by Webb are called Herbig-Haro (HH). These space objects are formed when “stellar winds or jets of gas expelled from these newborn stars form shock waves that collide with nearby gas and dust at high speeds.”
The image in question brings never-before-seen details of the shock wave and the symmetric jet that feeds it, due to spatial resolution around five to ten times greater than any previous image of HH 211.
By recording these unprecedented details, the researchers found that the outflow of matter from the object is relatively slow compared to young stars, or more evolved “protostars”, with similar types of flow.
The team of scientists found that the speeds of the innermost exit structures range from 80 to 100 kilometers per second. “However, the difference in speed between these sections of the outflow and the main material with which they are colliding — the shock wave — is much smaller,” explains the statement released by the agency.
