What is Nebula? Here is what NASA says about 2 nebulae captured by James Webb Space Telescope

NASA explains image of Carina Nebula and Southern Ring Nebula captured by James Webb Space Telescope.

What do you know about the nebula? Recently, when NASA released the first images from the James Webb Space Telescope, there were a total of 5 images including two nebulae – the Carina Nebula and the Southern Ring Nebula. But do you know what the nebula is? According to NASA Space Place, “A nebula is a large cloud of dust and gas in space. Some nebulae (more than one nebula) come from gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are forming. started.”

It is known that most of the hydrogen and helium forms the nebula. Nebulae exist in the space between stars – also known as interstellar space. The nebula closest to Earth is called the Helix Nebula. It’s the remnants of a dying star – perhaps one like the Sun. It is about 700 light years from Earth. To view and capture images of nebulae, astronomers use very powerful telescopes. Space telescopes such as NASA’s Spitzer Space Telescope and Hubble Space Telescope are used for the same.

Meanwhile, if you’re not aware of the two nebulae captured by the James Webb Space Telescope, here’s what you need to know:

1. Carina Nebula

According to information provided by NASA, the image captured by the Carina Nebula Telescope is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. The image reveals for the first time regions unseen before star birth. Known as the Cosmic Cliffs, Webb’s seemingly three-dimensional image shows a jagged mountain on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within NGC 3324, and the tallest “peak” in the image is about 7 light-years high.

Deep ultraviolet radiation from the nebula and the stellar wind have carved the cavernous region from the very massive, hot, young star located at the center of the bubble above the region shown in the figure.

2. Southern Ring Nebula

Describing the image of the Southern Ring Nebula captured by the James Webb Space Telescope, NASA said, “Some stars save the best for last. The faint star at the center of this scene has been sending out rings of gas and dust for thousands of years. In all directions, and NASA’s James Webb Space Telescope for the first time as revealed that this star is covered in dust.”

Two cameras on the web captured the latest images of the planetary nebula, listed as NGC 3132 and informally known as the Southern Ring Nebula. It is about 2,500 light-years away, NASA added.
