The James Webb Space Telescope has released an amazing image of the birth of a star

In each James Webb telescope image of space, matter and energy interact in a spectacular way, and more details are revealed to us than images from other telescopes. In a new image, we see a star that is only 100,000 years old.

This star is called L1527. Although 100,000 years seems like a long time, the birth process of this star has not yet been completed and its surroundings are surrounded by molecular clouds. Investigating this star is one of the reasons NASA (in collaboration with the European and Canadian space agencies) built James Webb. This telescope can see inside clouds of gas and dust and reveal the first stages of star formation.

Scientists The birthday picture of this star have been taken using the Mid-Infrared Instrument (MIRI). This protostar is still growing and absorbing material from the surrounding protoplanetary disk. We can see this disk as a relatively dark and horizontal line in the center of the image.

The birth of a star

This is the prologue The star of the main sequence is not; For this reason, unlike the sun, its light is not the result of nuclear fusion. Of course, there is probably some deuterium fusion going on in its core. The star's energy comes from its gravity, which compresses and heats nearby material. Also, incoming materials collide with existing gases and shock waves are created. The energy of these collisions lights up the star and the gases around it.

This protostar creates a powerful magnetic field by attracting more material. The combination of this magnetic field with the rotation of the star causes the material around the star to be ejected.

As the mass of the star increases, part of this mass is thrown out from the poles of the star in the form of beautiful jets that look like an hourglass in this image. These jets create arc shocks in the material around the star, which can be seen as filamentary structures.

There are polycyclic aromatic hydrocarbons (PAH) in the surrounding environment of the star. PAHs are organic compounds that are abundant in the universe and may have been one of the factors in the formation of life on earth. They are shown in blue in this image in stringy structures.

The red area in the center of the image is a thick layer of gas and dust around the star that glows with the star's energy. There is a mixture of different materials in the white area between the red and blue parts; including an abundance of PAHs, ionized gases such as neon, and other hydrocarbons.

Over time, strong outflows wash away the gas and dust surrounding the protostar, leaving only a protoplanetary disk around it. Eventually, this star becomes a main sequence star (like the Sun) and can be easily observed. Over time, the planetary system of this star will form.

This is not the first time that the James Webb telescope has observed the star L1527. In 2022, James Webb observed this star with the Near Infrared Camera (NIRCam), which you can see below.

There are many questions about the birth of stars that scientists hope the data from the James Webb telescope will bring them closer to the answer. For example, they still don't know how and when nuclear fusion will start. It is also not known how the star's magnetic field is formed and its role in its collapse and rotation.
