The Hubble Space Telescope has delivered remarkable images showing Jupiter’s Great Red Spot displaying bounce-like movements, similar to a kickball. This phenomenon was observed during Hubble’s annual check-up of the solar system’s outer planets. The Great Red Spot is a massive storm, larger than the Earth, that has been raging on Jupiter for at least 150 years. The storm’s size and color have fluctuated over the years, but the recent images show a particularly unusual movement.
Scientists from NASA’s Goddard Space Flight Center and the Space Telescope Science Institute explained this movement as a natural oscillation or vibration, similar to a bouncing ball. The storm is not physically moving across the planet; instead, its 90-day oscillation is considered a “beating” in its longitude.
The Hubble telescope, launched in 1990, has been instrumental in observing and studying the outer planets of our solar system, including Jupiter. It utilizes high-resolution and high-speed observations of atmospheric changes in Jupiter to understand better the gas giant’s weather patterns.
Although Jupiter’s Great Red Spot has been shrinking over the years, the recent observations do not necessarily suggest that the storm will disappear anytime soon. The storm’s longevity is attributed to its ability to absorb smaller storms and maintain its strength, like a self-sustaining hurricane. This absorption often leads to changes in color, size, and shape, making it a subject of great interest for astronomers.
Moreover, the Great Red Spot isn’t the only storm on Jupiter. The planet is known for its turbulent and dynamic atmosphere, with dozens of smaller storms raging across its surface. These storms are fueled by Jupiter’s rapid rotation and heat rising from the planet’s interior.
These observations are part of the Outer Planets Atmospheres Legacy (OPAL) program, which helps scientists understand the atmospheric dynamics and evolution of our solar system’s gas giant planets. Conducting annual monitoring of these planets allows for the detection of changes in their storms, winds, and clouds. Understanding these changes can provide insights into the weather patterns of planets outside our solar system.
The Hubble telescope’s observations also serve as a precursor to NASA’s upcoming mission, the James Webb Space Telescope, set to launch in November 2021. The Webb Telescope will offer a more profound and detailed look into the atmospheres of Jupiter and other planets, providing scientists with more data to understand these celestial bodies better.
