What is a nebula? | The Sun

SCIENTISTS released a photo showing the first glimpse into other galaxies, including the dying nebula.

The image was taken from NASA’s James Webb Space Telescope revealing never before seen details of the Southern Ring planetary nebula.

What is a nebula?

The James Webb Space Telescope took an image of a nebula that's locations 2,500 light-years away from Earth.

A nebula consists of dust and clouds in space and is formed by the debris of a dying star.

Nebulae – more than one nebula – will eventually form creating a star nursery, where new stars are born from the dust of those that had died.

The dust and gases contained in a nebula are mostly made up of helium and hydrogen which begin to spread far apart, creating a center of gravity.

Over time, the gravity pulls in the dust and gas, making the nebula grow.

As it becomes bigger, the gravity gets stronger causing it to collapse in on itself.

When this happens, the cloud at the center begins to heat up, creating the core beginning of a star.

What photos did the telescope capture of the Nebula?

New photos released by Nasa show a scientific phenomenon as the Southern Ring Planetary Nebula burns out.

However, the image shows not only just the dying nebula but a star that is forming within the nebula itself.

"As the star is dying, in its last dying throes, it starts to shake. It pulsates. And at the end of that, poof, it comes out," Klaus Pontoppidan, JWST's project scientist at NASA's Goddard Space Flight Center, told reporters after unveiling the images.

"So you see what the star did just before it created this planetary nebula.

"I find it fascinating because it's like geological layers, and you can see the history of its last moments."

Why are the images groundbreaking?

The James Webb Space Telescope was built over more than two decades and cost $10million.

It was released into space on December 25, 2021, and traveled a million miles from Earth.

The telescope captured groundbreaking photos that will alter the way scientists look at space.

NASA said the image captures part of a "stellar nursery called NGC 3324 at the northwest corner of the Carina Nebula," which is about 7,600 light-years from Earth.

The images provided will allow scientists to study the Nebula and find out more about stars that have or will explode and reform.

Scientists are using the images to find out more about galaxies than ever before, but The New York Times reported that NASA Administrator Bill Nelson said we are just seeing a tiny fraction of what is out there.

"If you held a grain of sand on the tip of your finger at arm's length, that is the part of the universe you are seeing — just one little speck of the universe," Nelson said.
