Pictures of the Crab Nebula
NASA's James Webb Space Telescope has captured stunning new views of an astronomical nebula, revealing previously unknown details. A nebula is a cloud made up of gas and dust, and this type of cloud is often made up of the debris of dying or exploding stars.
This nebula is also a place where new stars can form, as gas and dust are the basic materials for the star formation process.
Astronomers estimate that there are tens of thousands of nebulae in the Milky Way alone, and the James Webb Space Telescope recently trained its lenses on the Crab Nebula, located about 6,500 light-years away.
NASA has published a new image of the Crab Nebula, clearly showing a small white dot at its center.
About 1,000 years ago, a massive star exploded past the terminal phase into a supernova, sending its hot, blazing innards into space. However, the star's dense core remained intact, and it is the Crab pulsar that lives on at the nebula's center until today.
This pulsar is rotating rapidly and charging the gaseous materials surrounding it. The James Webb Space Telescope has revealed previously unknown details about the charged particles that move around the strong magnetic fields produced by this star. These particles move at relative speeds, and radiate strongly at certain times, and are used Sometimes in X-ray imaging, this type of radiation is known as synchrotron radiation.
