LIVE Techno – Stars are astronomical objects that have light, this is because of the nuclear reactions that occur in their core. Stars are one of the basic components of the universe which are sources of light, heat and energy in the cosmos.
Reporting from BBC, Friday, November 10 2023, recently made observations show how stars are born and the process of their formation. All of this cannot be separated from the role of the James Webb space telescope, which was just launched by NASA and the European Space Agency.
NASA is excited to reveal the secret of star birth
Through his telescope, he showed the protostar HH 212 which is about 1,300 light years from Earth.
HH 212 was first discovered in 1993, located near Orion’s Belt and astronomers have spent the last three decades taking images to reveal how this budding star slowly formed.
However, according to Mark McCaughrean, a senior advisor at the European Space Agency, this is the first time scientists have seen “stunning color images” of protostars, which was previously impossible with telescopes on Earth.
The new image reveals intricate details of star formation, with symmetrical plumes of pink emission gas originating from both poles of the protostar.
McCaughrean explains that these neon bursts, known as jets or outflows, are a byproduct of star birth, and their bright colors indicate the presence of hydrogen molecules.
“When the lump of gas in the center solidifies, it starts to spin,” he explained in an interview with the BBC.
“But if it spins too fast, it gets thrown out, so something has to take away its angular momentum… We believe it’s the jet and the outflow.” he continued.
According to the BBC, the view captured by the telescope “will appear similar” to a past stage of our Sun’s development.

The James Webb Space Telescope, launched two years ago, is located more than a million miles away at a place called “Lagrange Point 2,” and has the ability to take images from space, providing clues about the formation of stars and planets.
“Webb has provided a more complex understanding of galaxies, stars and planetary atmospheres beyond our solar system than ever before, laying the foundation for NASA to lead the world in an era of scientific discovery and exploration of habitable planets,” said Nicola Fox, associate administrator of the Directorate NASA Science Mission.
He praised the telescope’s ability to revolutionize understanding of the cosmos by being able to see “light from distant corners of the universe for the first time.”
“Each new image is a new discovery, providing the impetus for scientists around the world to ask and answer questions that previously only existed in dreams,” he added.
