NASA’s James Webb Telescope has captured the “once-hidden” beginnings of a very young star during an exploration to find the first galaxies.
On November 16, NASA announced details of the unprecedented characteristics of a protostars are named L1527. The James Webb Telescope’s (JWST) near-infrared camera played a key role in bringing this image to real light.
Photographs of protostars show a shape “Hourglass” like burning in the darkness of space. Under the infrared light, once-invisible clouds of dust appeared around the area, while in the center of the hourglass was a young star.

NASA’s James Webb Telescope has captured the “once-hidden” beginnings of a very young star.
To use Infrared camera (NIRCam)James Webb can not only penetrate the dark clouds that cover protostars in past telescopes, but also look back in time to see when the young star is eating a cloud of material to grow.
Dr. Klaus Pontoppidan, a scientist at the Space Telescope Science Institute based in Baltimore, Maryland, told Newsweek that the opaque image would not have appeared as clearly without infrared light. However, James Webb can penetrate the dust and, like a thermal camera, see through the fog.
The most stunning feature of the image are the blue and orange clouds created when material is ejected from the protostar and collides with surrounding matter.
“The color itself is due to layers of dust between the James Webb Telescope and the clouds. The blue areas are those where the dust is the finest. The thicker the dust layer, the less blue light escapes, creating orange pockets.said Mr. Pontoppidan.
According to Pontoppidan, the distance between the protostar and Earth is about 500 light years, which seems far away, but it is actually one of the closest young stars and is also the average distance at which young systems are formed. According to him, this shape is not very different from the shape of the Sun and the solar system 4.6 billion years ago.
NASA said it was a Class 0 protostar, the earliest stage of star formation, and is estimated to be about 100,000 years old. It is still expanding and absorbing gas and has not yet reached its final mass. Unlike mature stars, this protostar has not yet produced its own energy through nuclear fusion, an essential characteristic of stars.
“As the protostar continues to gain mass, its core gradually compresses and approaches stable nuclear fusion. The scene shown in this image shows L1527 doing just that. The surrounding molecular cloud consists of dense dust and gas drawn toward the center, where the protostar resides.according to NASA.
NASA then explained that as this material fell, it would wrap around the central area of the hourglass shape, creating a dense disk of material, called a disc. accretion disk – and this is what provides matter for the stars.
“The existence of the protostar has been known for decades due to its brightness, but the limited resolution of previous instruments made it look like a blob. The new image opens a window into what our Sun and solar system looked like in their infancy.NASA said.
Still according to the agency, images captured by the James Webb Telescope are 10 times sharper than images captured by the Spitzer Space Telescope, launched in 2003 and ended operations in 2020.
“In general, it teaches us about our origins. They act like time machines and allow us to go back in time to see how the universe was formed.commented NASA.
