Jupiter’s Great Red Spot has been observed for about 190 years, shrinking from roughly 39,000 km to around 14,000 km across, though still wider than Earth; its long-term change is tracked annually by the Hubble Space Telescope, while shorter-term 90-day fluctuations occur; the reasons for the shrinkage are not settled and future changes could lead to the storm breaking up or stabilizing at a smaller size.
Voyager 2's 1979 flyby provided the first detailed study of Jupiter's Great Red Spot, revealing its massive size, dynamic structure, and longevity, which continues to challenge our understanding of planetary storms, although its size and appearance are still changing today.
New research suggests that the Great Red Spot observed by Giovanni Domenico Cassini in 1665 is not the same storm seen today on Jupiter. The original storm likely disappeared between the mid-18th and 19th centuries, and the current Great Red Spot has persisted for about 190 years. The study highlights the differences in size and duration between the two storms, with the current Great Red Spot being much larger and more enduring.
A new study suggests that Jupiter's Great Red Spot is not the same storm observed by Giovanni Cassini in 1665, known as the "Permanent Spot." The original spot likely disappeared between the mid-18th and 19th centuries, and the current Great Red Spot, discovered in 1831, is a newer storm. The research indicates that the Great Red Spot has been shrinking and may eventually disappear, similar to its predecessor.
The Hubble Space Telescope captured new images of Jupiter, revealing stormy weather and a shrinking Great Red Spot. The images show swirling storms and tumultuous cloud bands, indicating a lot of activity in Jupiter's atmosphere. The Great Red Spot, a massive storm on Jupiter, has been shrinking at an alarming rate, raising questions about its future. The images also show other smaller storms and features on the gas giant, providing valuable insights into the dynamics of Jupiter's atmosphere.
NASA's Juno spacecraft captured a stunning image of Jupiter's Great Red Spot, a storm twice the size of Earth that has been churning for over 350 years. The image, taken from about 13,917 km away, shows the storm surrounded by spiralling tan, orange, and red slivers. The Great Red Spot has been shrinking since it was last measured in 1979, with recent studies by Juno indicating that the storm plunges around 200 miles beneath the planet's clouds. Juno, launched in 2011, is now in the third year of its extended mission to study Jupiter.
NASA's Juno spacecraft captured a striking image of Jupiter's Great Red Spot, revealing the iconic storm to be twice as large as Earth and reaching about 200 miles beneath the planet's clouds. The high-pressure region has been churning an anticyclonic storm for over 350 years, but has been shrinking in size over the past four decades. Juno's observations also indicate that winds in the Great Red Spot can reach speeds of up to 400 miles per hour, and the spacecraft is currently in the third year of its extended mission to study Jupiter and its moons.
Jupiter's Great Red Spot, a massive storm on the planet's southern hemisphere, is shrinking and may soon become the smallest ever recorded since observations began 359 years ago. Recent measurements by astrophotographer Damian Peach suggest that its diameter has reached a record-breaking small size of 12,500 kilometers (about 7,770 miles). The shrinking size, coupled with the surrounding turbulent environment, has made the Great Red Spot less conspicuous to observers. It remains uncertain whether the storm will continue to shrink or eventually disappear altogether.
NASA celebrates Jupiter's opposition in the night sky by releasing a stunning ultraviolet image of the gas giant taken by the Hubble Space Telescope. The image showcases the planet's candy-colored appearance, with its famous Great Red Spot appearing as a dazzling blue gem. Ultraviolet wavelengths reveal how sunlight makes minerals glow and can display cosmic phenomena. Hubble researchers plan to use the data to map deep water clouds and define 3D cloud structures in Jupiter's atmosphere. Despite its age, Hubble continues to provide valuable data on the evolution of Jupiter and other celestial objects.
NASA's Hubble Space Telescope has captured a stunning ultraviolet image of Jupiter, revealing the planet's storms and highlighting the Great Red Spot. The image, created by combining data from three different ultraviolet filters, will help scientists study Jupiter's atmosphere and map water clouds deep within its interior. The polar regions of Jupiter appear less prominent in the image due to differences in particle size, composition, or altitude. This latest observation adds to decades of research conducted by Hubble on Jupiter, including the famous observation of the comet Shoemaker-Levy collision in 1994.
NASA's Astronomy Picture of the Day shows Jupiter's two largest moons, Europa and Io, crossing the gas giant and its Great Red Spot, captured by NASA's Cassini spacecraft. Io is the third-largest of Jupiter's four Galilean moons, while Europa is the smallest but has more water than Earth. The spacecraft used the Visual and Infrared Mapping Spectrometer (VIMS) to capture the image. Jupiter is currently being visited by NASA's robotic Juno spacecraft, while ESA's Jupiter Icy Moons Explorer (JUICE) is en route.
New images taken by the Hubble Space Telescope reveal a smoggy cap growing around Uranus' north pole as it moves toward its northern summer season. Meanwhile, Jupiter's Great Red Spot is at its smallest since regular observation began 150 years ago, but a new giant storm may be forming north of Jupiter's equator in the form of a "vortex street" consisting of a row of interlocking cyclones that spin in alternating directions.
