Written by Amira Shehata Tuesday, October 31, 2023 08:00 PM NASA’s James Webb Space Telescope revealed the Crab Nebula, which is the remains of a stellar explosion that lit up the sky nearly 1,000 years ago. It is also bright enough to be seen on Earth from 6,500 light-years away. . According to what was reported by the British newspaper “Daily Mail”, T. Timim from Princeton University said: “Webb’s sensitivity and spatial accuracy allow us to accurately determine the composition of the ejected material, especially the iron and nickel content, which may reveal the type of explosion that produced the Crab Nebula.” A team is searching for answers about the origins of the Crab Nebula, and NASA said that to find the “pulsar heart” of the Crab Nebula in the image, viewers must “follow the wisps that follow a circular, ripple-like pattern in the middle to the bright white dot in the center.” “Far from the core, follow the thin white ribbons of radiation,” the space agency added, explaining, “The sinuous strands are closely grouped together, illustrating the structure of the pulsar’s magnetic field, which sculpts and shapes the nebula.” James Webb is also not the first telescope to capture an image of the Crab Nebula, NASA’s famous Hubble Space Telescope also did so in 2005. However, because Webb can see in the infrared, it provides an unprecedented “clear” view of the explosion Starburst with great detail. “In the central regions, emissions from dust grains (yellow, white and green) were mapped by Webb for the first time,” NASA said. Additional aspects of the Crab Nebula’s inner workings have become clearer and can be seen in greater detail in the infrared light captured by Webb. It is about 6,500 light-years from Earth, 11 light-years across, and expanding at a speed of 930 miles per second.
