The James Webb Telescope captures the first moments of the formation of a new star

Because of its age and brightness in far infrared light, L1527 is considered a class 0 protostar, the first stage of star formation.

The James Webb Space Telescope revealed with its Near Infrared Camera (NIRCam) the previously hidden features of Protostar L1527, embedded in a cloud of material that fuels its growth; The image provides a glimpse of the formation of a new star.

Despite the mess L1527 makes, it’s a little bit 100,000 yearsis a relatively young body, according to the European Space Agency (ESA) in a statement.

Because of its age and brightness in far infrared light, L1527 was considered 0 class protostarthe first stage of star formation.

These types of protostars are still surrounded by a dark cloud of dust and gas And a long way to go before they become full-fledged stars.

L1527 is not yet generating its own energy through hydrogen nuclear fusion, which is an essential property of stars. Although its shape is mostly spherical, it is also unstable.

As the protostar continues to accumulate mass, Its core is gradually compressed And close to stable nuclear fusion.

The scene shown in Webb’s new image reveals that L1527 does just that.

The surrounding molecular cloud consists of dense dust and gas that is being pulled towards the center where the protostar is located. When matter falls, it rotates around the center.

This results in a dense disk of material, known as an accretion disk, which feeds material into the protostar. As it gains more mass and becomes more compressible, the temperature of its core will rise, eventually reaching the threshold for initiating nuclear fusion.

The disc shown in the image as Dark stripe in front of the bright centerwith a size similar to that of our solar system.

These fiery clouds within the star-forming region of Taurus are visible only in infrared light, making them an ideal target for Webb, according to the European Space Agency, ESA.

“Ultimately, this view of L1527 provides a window into what our sun and solar system looked like in their infancy,” he concludes.
