What is a nebula? Here’s what NASA has to say about 2 nebulae captured by the James Webb . Space Telescope
Here’s what NASA explains about the James Webb Space Telescope image of the Carina Nebula and the Southern Ring Nebula.
What do you know about nebulae? Recently, when NASA released the first images from the James Webb Space Telescope, there were a total of five images including two of the nebula – the Carina Nebula and the Southern Ring Nebula. But do you know what a nebula is? According to NASA Space Place, “A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) are produced from gas and dust caused by the explosion of a dying star, such such as a supernova other than nebulae are regions where new stars are beginning to form.”
It is known that it is mostly hydrogen and helium that make up the Nebula. Nebulae exist in interstellar space — also known as interstellar space. The closest known nebula to Earth is called the Helix Nebula. It is the remnant of a dying star — possibly a star like the Sun. It is about 700 light-years from Earth. To see and photograph nebulae, astronomers use very powerful telescopes. Space telescopes such as NASA’s Spitzer Space Telescope and the Hubble Space Telescope are also used for the same purpose.
Meanwhile, if you don’t know about the two nebulae captured by the James Webb Space Telescope, here’s all you need to know:
1. The Carina Nebula
According to information provided by NASA, the image taken by the telescope of the Carina Nebula is actually the edge of a young, nearby star-forming region called NGC 3324 in the Carina Nebula. The images reveal previously invisible star-forming regions for the first time. Called the Cosmic Cliffs, Webb’s seemingly holographic picture looks like craggy mountains on a moonlit evening. It is, in fact, the edge of the giant gas chamber located within NGC 3324, and the highest “peaks” in the image are about 7 light-years high.
The cave area has been created from the nebula by intense ultraviolet radiation and stellar winds from extremely large, hot young stars, located at the center of the bubble, above the area shown in the figure. image.
2. Southern Ring Nebula
Explaining the image of the Southern Ring Nebula captured by the James Webb Space Telescope, NASA said, “Some stars save the best in the end. The star is fainter at the center of this scene. has been creating rings of gas and dust for thousands of years in all directions, and NASA’s James Webb Space Telescope has revealed for the first time that the star is covered in dust.”
Two cameras on Webb captured the latest image of this planetary nebula, cataloged NGC 3132, and informally known as the Southern Ring Nebula. NASA adds that it is about 2,500 light-years away.
