Web Space Telescope Captures a Cosmic Ring #NASA #Telescope #NasaUpdates

The Web Space Telescope is a powerful observatory that can capture stunning images of the cosmos in infrared light. One of its recent discoveries is a cosmic ring, also known as a planetary nebula, which is the remnant of a dying star. In this article, we will explore what a planetary nebula is, how the Web Space Telescope captured its image, and what it can tell us about the origin and evolution of stars and planets.

A planetary nebula is a cloud of gas and dust that forms when a star like our Sun runs out of fuel and ejects its outer layers into space. The core of the star remains as a white dwarf, which emits intense ultraviolet radiation that ionizes the surrounding gas and makes it glow in different colors. The shape and structure of a planetary nebula depend on various factors, such as the mass and rotation of the star, the presence of magnetic fields, and the influence of a binary companion.
