The James Webb Telescope displays new images of the “Crab Nebula”

One feature that the James Webb Space Telescope shows very clearly in the Crab Nebula is the dense, rotating pulsar at the nebula’s center. The pulsar is hardly visible in the Hubble image (left).

NASA’s James Webb Telescope has captured never-before-seen details of the Crab Nebula.

The new image shows ghostly tendrils and the dense core of an exploding star in exquisite detail.

The Crab Nebula is the remains of a star that exploded 6,500 light-years away.

NASA’s James Webb Space Telescope has new images of one Breathtaking fog Which reveals unprecedented details.

A nebula is a cloud of gas and dust mostly It arises from the debris of dying or exploding stars. These clouds are also the cradle of New starsGas and dust provide the building blocks for star formation.

Astronomers estimate that it exists only in Milky Way There are tens of thousands of nebulae, and the James Webb Space Telescope recently focused on a very nearby nebula: the Crab Nebula, located about 6,500 light-years away.

Examine the Crab Nebula in stunning detail

Published on Monday NASA publishes a new image of the Crab NebulaWhich clearly shows a small white dot in its center. It is the heart of the Crab Nebula, known as the Crab Pulsar.

About 1,000 years ago, an extremely massive star exploded as a supernova, spewing its hot insides out into space. However, the dense core of this star remained intact, and today it forms the Crab pulsar, which lives in the center of the nebula.

A pulsar is a rapidly rotating object that, in the case of the Crab Nebula, charges up the gaseous matter surrounding it, which the James Webb Space Telescope has revealed for the first time in stunning detail – something The Hubble Space Telescope couldn’t show itWhen she set her sights on cancer in 2005.

Hubble observes space primarily using the same type of light we see, visible light. So Hubble couldn’t do thatto capture the fuzzy, ghostly, thin white filaments of charged particles seen by the James Webb Space Telescope, which recently viewed the nebula in infrared light.

These charged particles move around the strong magnetic fields generated by the Krebs pulsar. They move at relativistic speeds, a fraction of the speed of light, and emit strong light, sometimes into space. X-ray imaging It is used and known as synchrotron radiation.

The other colorful tendrils of gas and dust that you see in the picture are remnants An extinguished star. For example, ionized sulfur appears reddish-orange, ionized iron appears blue, and dust appears greenish-yellow.

“Webb’s sensitivity and spatial resolution allow us to precisely determine the composition of the ejected material, especially the iron and nickel content,” explains Tee Timm, who led the team that used the infrared instruments on the James Webb Space Telescope to image the Crab Nebula.

NASA said that for the first time in 20 years, Hubble will provide a new image of the Crab Nebula for comparison sometime next year.
