At present, the latest Hubble Space Telescope observation image shows the local characteristics of the shrimp nebula, which is mottled and dazzling, including the bright and luminous gas. The prawn nebula is a huge stellar nursery in the constellation Scorpius, about 6000 light-years away from the earth. Although the prawn Nebula extends 250 light-years and covers a space equivalent to four times the size of the full moon, the light it releases is mainly at wavelengths that cannot be detected by human eyes, which is very weak for earth observers.
The prawn nebula is a huge stellar nursery in the constellation Scorpius, about 6000 light-years from earth.
However, the Hubble Telescope captured part of the prawn Nebula in visible and invisible infrared light.
The shrimp Nebula lies to the south of Antares in the constellation Scorpius. The Hubble Space Telescope focused image is only a small part of the huge star forming region.
The prawn nebula, also known as IC 4628, is an emission nebula, which means that its gas is ionized by the radiation of neighboring stars. The stellar radiation comes from the electrons in the hydrogen atoms of the prawn Nebula stripped by the super massive stars. When the electrons are activated by re combining with the hydrogen nuclei and are restored from the high-energy state to the low-energy state, they release energy in the form of light, causing the gas in the nebula to glow. In this image, Red indicates the presence of ionic iron release.
It is reported that this Hubble observation image is an investigation of the super large and medium-sized "protostars" or newly born stars. Astronomers use the infrared sensitivity of Hubble 3 wide field camera to find ionized hydrogen decomposed by the ionized ultraviolet rays of the protostars, stellar jets and other features.
