A new image from the James Webb Space Telescope unveils the mesmerizing formation of a protostar, shedding light on the birth of stars. Located approximately 1,300 light-years away from Earth, the protostar known as HH 212 was initially detected in 1993 near the Belt of Orion. Over the past three decades, astronomers have diligently gathered images to unravel the gradual development of this budding star. However, it is for the first time that scientists have captured a vivid and detailed color image of HH 212, made possible by the advanced capabilities of the James Webb Space Telescope.
The remarkable image showcases the intricate process of star formation, revealing symmetrical pink plumes of gas emissions emanating from both poles of the protostar. These neon bursts, scientifically termed as jets or outflows, are considered vital byproducts of star birth. The vibrant hue of these emissions suggests the presence of molecular hydrogen. Mark McCaughrean, a senior advisor at the European Space Agency, explains that as the gas in the central region compresses and rotates, it faces the risk of dispersing due to excessive rotation. To counter this, the protostar utilizes jets and outflows to dispose of the excess angular momentum.
Scientists assert that the scene captured by the James Webb Space Telescope would have appeared similar during the developmental stage of our very own sun. This unprecedented image not only provides crucial insights into the phenomenon of star formation but also signifies the significant progress in our understanding of galaxies, stars, and planetary atmospheres. Situated over one million miles away at “Lagrange point 2,” the James Webb Space Telescope continues to revolutionize space exploration by capturing images from deep space, enabling us to uncover the mysteries of star and planet formation.
The associate administrator of NASA’s Science Mission Directorate, Nicola Fox, highlights the telescope’s contribution to scientific discovery and the quest for potentially habitable worlds. She lauds the James Webb Space Telescope’s ability to reshape our comprehension of the universe by capturing light from distant corners that were previously inaccessible. Each new image acquired by this remarkable telescope becomes a catalyst for scientific breakthroughs and empowers researchers worldwide to explore questions that were once unimaginable.
