The James Webb space telescope surprises, in its last image, with the incredible details of a stellar system in formation in Lynds 483 (L483), which is 650 years-old from distance, in the constellation of Serpens.
Specifically, the high resolution near -resolution infrared light captured by the James Webb telescope shows new details and a complex structure in this molecular cloud in which stars are formed.
In the center of the photograph you can see a fine vertical cloud -L483- that has a shaped shape to a sand watch with irregular edges. The lower lobe is slightly trimmed and the superior is seen in its entirety, narrowing at the top.
Two stars in formation are responsible for the glowing gas and dust ejections that shine in orange, blue and violet in this color in color published this Friday, they inform two notes of the European Space Agency (ESA) and the US NASA agency.
Especially dense molecular clouds such as L483 are described as dark nebulae due to their ability to obscure the environment. These, against what it may seem, are the most fertile environments for the formation of stars.

A protoestrella is a condensation of interstellar gas and dust whose gravitational attraction makes collapse on itself and form a star. The two proto -stars responsible for this scene captured by the Webb are located in the center of the sand clock.
Over tens of thousands of years, they have periodically expelled part of the gas and dust, throwing it in the form of fast and compact jets, and slightly slower flows that ‘travel’ through space.
When the most recent ejections collide with the oldest, the material can ‘wrinkle’ and turn based on the densities of what it collides. Over time, chemical reactions inside these ejections and in the surrounding cloud produce a series of molecules, such as carbon monoxide, methanol and other organic compounds.
Over time, scientists will calculate how much material the stars have expelled, what molecules were created when the material collided with each other and how dense each area is.
Within millions of years, when the stars have finished forming, each will have approximately the mass of our sun.
Its output flows will have cleaned the area, sweeping these semi -transparent ejections and there will only be a small gas and dust disk in which planets could be formed.
L483 owes its name to the American astronomer Beverly T. Lynds, who published extensive catalogs of dark and bright nebulae in the early 1960s.

The catalogs provided detailed maps of the dense clouds of dust where the stars are formed, fundamental resources for the astronomical community decades before the first digital files were available and internet access was generalized.
