James-Webb sends us sublime images of the Orion Nebula, the closest cradle of stars to Earth

A French-Canadian team was able to probe the Orion Nebula with the piercing eyes of the James-Webb Space Telescope. The images are sublime and full of information for researchers who continue to study them.

The orion nebulaorion nebula is a vast complex of gasgas and dust that extends into the Milky Way just 1,300 light years from Earth, towards the constellation of the homonymous great hunter. It is almost the forming region ofstarsstars closer to us, accessible to all with an astronomical telescope or telescope. It is also possible through binoculars to distinguish its brighter fraction, where the stars of the Trapezium cluster are encamped. The latter is a asterismasterism whose name derives from its suggestive geometric shape drawn by the brightest stars. The whole can be guessedeyeeye naked at the height of the dagger compared to the giant gategate on his belt.

In these new images taken by James-Webb, the two brightest stars in front of the wallwall of gas called barbar di Orione ”belong to the Trapezium group. They originated there not long ago: around 300,000 years ago, according to a study. Warm, massive, they overflow with energy and their violent splendor redraws the entire surrounding landscape, fragmenting and eroding it.

All the it mattersit matters accumulated in this region of the Milky Way, he is thus overwhelmed by his most zealous progeny. Radiation ultravioletultraviolet a lightning from the star named θ 2Orionis A, as you can see, shatters the wall of gas, thus profoundly modifying its structure. The densest webs of filaments will last longer to resist the taunt of the raging stars of the Trapezius, while the thinner ones will be swiftly wiped out. The most important members of the cluster (out of scope in the image), on the other side of the gas wall, have already made their way inside the large cloudcloud molecular, and by digging an immense cavity visible in the Orion Nebula (the same thing in the Tarantula Nebula observed recently by James-Webb).
