NASA’s James Webb Space Telescope recently captured an incredible image of a dying star, giving us a glimpse into its fate and what might happen to our own Sun someday.
This stunning photo shows the Helix Nebula, located 650 light-years away. It’s sometimes called the “Eye of Sauron” because of its shape. But don’t be fooled by the name “planetary nebula”; it has nothing to do with planets. Instead, it’s all about stars.
In the image, the inner ring reveals a bright, expanding cloud of hot material. This cloud comes from a star that has shed its outer layers to reveal a dense core, known as a white dwarf. This core is now releasing intense radiation into the surrounding cloud.
When a star like our Sun reaches the end of its life, it swells into a red giant and eventually sheds its outer layers. This process doesn’t just leave space empty. The materials that escape are vital for creating new stars and planets. Much like how decomposing plants and animals nourish the Earth, star deaths recycle cosmic materials throughout the universe.
According to NASA, the Webb image shows different colors representing various gas temperatures. The blue areas are the hottest gases, while yellower regions contain cooler hydrogen and dust where complex molecules can form.
Interestingly, this white dwarf could have a companion star nearby. If they orbit too closely, the white dwarf can pull material from its partner. When enough builds up, it can trigger a nova, a spectacular explosion that surpasses the brightness of the nebula.
Research shows that these stellar processes are not just fascinating; they are essential to the formation of future solar systems. As the universe evolves, these dying stars contribute to a cycle of creation, enriching the cosmos in ways we are still discovering.
