The James Webb Space Telescope has been taking breathtaking images since its launch. One of the best was published in the same November in This is a protostar, reflecting the cosmic hourglass.. Now you can download it to make it your background.

Thanks to James Webb’s photographs, we can now take a look at the dark cloud L1527. Here embedded protostar barely 100,000 years old. The image was taken with the space telescope’s NIRCam (Near Infrared Camera) instrument. The protostar is thus shown illuminating the body of the nebula with infrared light, offering impressive and almost artificial vision.

Due to the infrared nature of light, this vision is only possible with cameras that can see in this spectrum. This means that if we went into space and tried to look at the same picture, we would find something completely different. For this reason, James Webb’s infrared cameras are of great importance. They allow us to see and study celestial objects that we would otherwise not be able to see.

On the neck of an hourglass we can see the protoplanetary disk. It is a disk of gas and dust that surrounds a protostar. This region would later become a solar system with planets and other celestial bodies within.

James Webb reveals more about this interesting nebula

As the star grows and absorbs material from the nebula, it also ejects it. A) Yes, the cavities we see in the image have been generatedas the material expands in space and collides with surrounding matter.

The colors in the image also matter. As explained on the telescope’s website, “colors due to layers of dust between Webb and clouds“.Blue are the areas where the dust is thinnest. The largest concentrations of material are those that seep in this color, creating large orange pockets in the nebula.

In addition, James Webb also discovered filaments of molecular hydrogen that are impacted when the protostar ejects material. These shocks prevent the possible formation of new stars. which would otherwise form over the entire length and width of the cloud. Now the protostar dominates the entire region, taking most of the material.

L1527 still is in the earliest stage of the life of a forming star. He still has a long way to go before he emerges from his dust cocoon and becomes a full-fledged star. It cannot yet generate its own energy through the nuclear fusion of hydrogen, which is required for any star.

Its shape, mostly spherical, is also unstable, taking the form of a small, hot, puffy clump of gas that has a mass between 20 and 40% of our Sun’s mass.

If you want to get an idea of ​​the scale of the image elements, keep in mind that the small protoplanetary disk It is the size of our solar system.. So we look back at our own system in its infancy. Little by little, the disk material will become more concentrated, leading to the formation of planets and other celestial bodies.
