Launched in 1977, the twin Voyager probes are NASA’s longest-operating mission and the only spacecraft ever to explore interstellar space. 45 years on, Voyager 1 and 2 continue to provide us with observations of the farthest reaches of space. Our Voyager 1 spacecraft zoomed toward Jupiter in January and February 1979, capturing hundreds of images of Jupiter during its approach, including this close-up of swirling clouds around Jupiter’s Great Red Spot.

As NASA’s Juno mission completed its 43rd close flyby of Jupiter on July 5, 2022, its JunoCam instrument captured this striking view of vortices — hurricane-like spiral wind patterns — near the planet’s north pole. These powerful storms can be over 30 miles (50 kilometers) in height and hundreds of miles across. Figuring out how they form is key to understanding Jupiter’s atmosphere, as well as the fluid dynamics and cloud chemistry that create the planet’s other atmospheric features. A NASA citizen science project, Jovian Vortex Hunter, seeks help from volunteer members of the public to spot and help categorize vortices and other atmospheric phenomena visible in JunoCam photos of Jupiter. As of July 2022, 2,404 volunteers had made 376,725 classifications using the Jovian Vortex…

2022年7月20日 Jupiter and Ring in Infrared from Webb Image Credit: NASA, ESA, CSA, STScI; Processing & License: Judy Schmidt Explanation: Why does Jupiter have rings? Jupiter’s main ring was discovered in 1979 by NASA’s passing Voyager 1 spacecraft, but its origin was then a mystery. Data from NASA’s Galileo spacecraft that orbited Jupiter from 1995 to 2003, however, confirmed the hypothesis that this ring was created by meteoroid impacts on small nearby moons. As a small meteoroid strikes tiny Metis, for example, it will bore into the moon, vaporize, and explode dirt and dust off into a Jovian orbit. The featured image of Jupiter in infrared light by the James Webb Space Telescope shows not only Jupiter and its clouds, but this ring as well….

2022年7月17日 Europa and Jupiter from Voyager 1 Image Credit: NASA, Voyager 1, JPL, Caltech; Processing & License: Alexis Tranchandon / Solaris Explanation: What are those spots on Jupiter? Largest and furthest, just right of center, is the Great Red Spot — a huge storm system that has been raging on Jupiter possibly since Giovanni Cassini’s likely notation of it 357 years ago. It is not yet known why this Great Spot is red. The spot toward the lower left is one of Jupiter’s largest moons: Europa. Images from Voyager in 1979 bolster the modern hypothesis that Europa has an underground ocean and is therefore a good place to look for extraterrestrial life. But what about the dark spot on the upper right? That is a…

A new NASA citizen science project, Jovian Vortex Hunter, seeks your help spotting vortices – spiral wind patterns – and other phenomena in photos of the planet Jupiter. Another NASA citizen science project, called Junocam, seeks help from members of the public processing images from NASA’s Juno Mission and choosing targets for the spacecraft. However, the new Jovian Vortex Hunter project provides images that have already been processed by the science team, making it quick and easy for anyone to lend a hand. Categorizing the images will help scientists understand the fluid dynamics and cloud chemistry on Jupiter, which create dazzling features like bands, spots and “brown barges.” In this image from 2019, citizen scientist Kevin M. Gill created this image using data from the…

2022年6月17日 Good Morning Planets from Chile Image Credit & Copyright: Elke Schulz (Daniel Verschatse Observatory) Explanation: On June 15, innermost planet Mercury had wandered about as far from the Sun as it ever gets in planet Earth’s sky. Near the eastern horizon just before sunrise it stands over distant Andes mountain peaks in this predawn snapshot from the valley of Rio Hurtado in Chile. June’s other morning planets are arrayed above it, as all the naked-eye planets of the Solar System stretch in a line along the ecliptic in the single wide-field view. Tilted toward the north, the Solar System’s ecliptic plane arcs steeply through southern hemisphere skies. Northern hemisphere early morning risers will see the lineup of planets along the ecliptic at a shallower…

2022年4月27日 Moon Shadow on Jupiter Image Credit: NASA/JPL-Caltech/SwRI/MSSS; Processing & License: Thomas Thomopoulos Explanation: What is that large dark spot on Jupiter? It’s the shadow of Ganymede, Jupiter’s largest moon. When Jupiter’s moons cross between the Jovian giant and the Sun, they created shadows just like when the Earth’s moon crosses between the Earth and the Sun. Also like on Earth, if you were in a dark shadow on Jupiter, you would see a moon completely eclipse the Sun. Unlike on Earth, moon shadows occur most days on Jupiter — what’s more unusual is that a spacecraft was close enough to record one with a high-resolution image. That spacecraft, Juno, was passing so close to Jupiter in late February that nearby clouds and the dark…
