New Delhi, March 16: Jupiter, the fifth planet from the Sun, is the largest in our solar system, boasting a mass more than twice that of all other planets combined. Among its many wonders, the Great Red Spot (GRS) stands out as a colossal storm that has captivated scientists for centuries.
The GRS is a massive rotating storm, larger than Earth itself, and its mystery continues to intrigue researchers. Recent data from NASA’s Juno spacecraft and the Hubble Space Telescope has unveiled new insights about this enigmatic feature.
This spot is classified as an anticyclone, continuously swirling in Jupiter’s atmosphere. Its size is so immense that it could encompass the entire Earth. Astronomers have been observing it for at least 150 to 300 years. While it was once significantly larger, it has been gradually shrinking. In 2018, NASA’s Juno spacecraft captured stunning images that showcased its vibrant colors. Juno revealed that the storm’s base extends deep into the atmosphere, with some storms reaching depths of 100 kilometers, while the Great Red Spot plunges over 350 kilometers.
Juno is a solar-powered spacecraft that orbits Jupiter, aiming to uncover the planet’s origins, evolution, and the mysteries of the solar system’s giant planets. Recently, Hubble also provided valuable information about the GRS, indicating that it is not as stable as it appears. It oscillates like a jelly bowl. Scientists created a time-lapse film from Hubble’s images, demonstrating that the spot expands and contracts every 90 days. When it slows down, it widens, and when it speeds up, it narrows.
NASA researcher Amy Simon noted, “Under the Outer Planet Atmosphere Legacy Program, we observed that while there are slight changes in its motion, the way its size fluctuates was unexpected. Hubble’s high-resolution images clearly show that it shrinks and expands, but we currently lack a hydrodynamic explanation for this behavior.”
Furthermore, observations in ultraviolet light revealed that when the spot is at its largest, its center is the brightest, indicating less haze in the upper atmosphere. These changes occur daily, reflecting subtle variations in the storm’s color, size, and speed. According to scientists, this discovery will aid in understanding storms on Earth and facilitate the study of weather patterns on exoplanets.
