Explaining the 'Tiger Stripes' of Saturn's Moon Enceladus
Saturn's sixth-largest moon, Enceladus, is a fascinating celestial body that has been the subject of much scientific research. One of the most intriguing features of Enceladus is its "tiger stripes," which are long, narrow fissures on its surface that spew out plumes of water vapor and ice particles. In this article, we will explore what causes these tiger stripes and what they can tell us about Enceladus.
Introduction
Enceladus was discovered by William Herschel in 1789 and has been studied extensively by NASA's Cassini spacecraft since 2004. The moon is only 500 kilometers in diameter and is covered in a layer of ice that is thought to be up to 30 kilometers thick. Despite its small size, Enceladus is one of the most geologically active bodies in our solar system.
What are Tiger Stripes?
Tiger stripes are long, narrow fissures on Enceladus' surface that are approximately 130 kilometers long and 2 kilometers wide. There are four main tiger stripes on the moon, named Alexandria, Cairo, Baghdad, and Damascus after cities in the Middle East. These stripes are located near the south pole of Enceladus and are responsible for the plumes of water vapor and ice particles that emanate from the moon.
What Causes Tiger Stripes?
The cause of tiger stripes on Enceladus is still not fully understood, but scientists believe that they are related to the moon's internal heat. Enceladus has a subsurface ocean beneath its icy crust that is kept warm by tidal forces from Saturn's gravity. This heat causes the ice to melt and creates a liquid layer between the crust and the ocean.
As this liquid layer moves around, it creates pressure that builds up and is released through the tiger stripes. The plumes of water vapor and ice particles that are ejected from the stripes are thought to be a mixture of water from the subsurface ocean and organic compounds that are created by chemical reactions in the moon's interior.
What Can Tiger Stripes Tell Us About Enceladus?
The tiger stripes on Enceladus provide valuable information about the moon's internal structure and composition. By studying the plumes that are ejected from the stripes, scientists can analyze the chemical composition of Enceladus' subsurface ocean and search for signs of life.
In 2018, NASA's Cassini spacecraft detected complex organic molecules in the plumes of Enceladus, which are thought to be building blocks for life. This discovery has led to increased interest in exploring Enceladus further and searching for signs of life on the moon.
Conclusion
Enceladus' tiger stripes are a fascinating feature that provide valuable insights into the moon's internal structure and composition. By studying these stripes and the plumes that emanate from them, scientists can learn more about Enceladus' subsurface ocean and search for signs of life on this small but intriguing celestial body.
