2小时30分钟期间的木星
2024年1月19日 Jupiter over 2 Hours and 30 Minutes Image Credit & License: Aurélien Genin Explanation: Jupiter, our Solar System’s ruling gas giant, is also the fastest spinning planet, rotating once in less than 10 hours. The gas giant doesn’t rotate like a solid body though. A day on Jupiter is about 9 hours and 56 minutes long at the poles, decreasing to 9 hours and 50 minutes near the equator. The giant planet’s fast rotation creates strong jet streams, separating its clouds into planet girdling bands of dark belts and bright zones. You can easily follow Jupiter’s rapid rotation in this sharp sequence of images from the night of January 15, all taken with a camera and small telescope outside of Paris, France. Located just…

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…
哈勃望远镜的木星和缩小的大红斑
2022年1月9日 Hubble’s Jupiter and the Shrinking Great Red Spot Image Credit: NASA, ESA, Hubble, OPAL Program, STScI; Processing: Karol Masztalerz Explanation: What will become of Jupiter’s Great Red Spot? Gas giant Jupiter is the solar system’s largest world with about 320 times the mass of planet Earth. Jupiter is home to one of the largest and longest lasting storm systems known, the Great Red Spot (GRS), visible to the left. The GRS is so large it could swallow Earth, although it has been shrinking. Comparison with historical notes indicate that the storm spans only about one third of the exposed surface area it had 150 years ago. NASA’s Outer Planets Atmospheres Legacy (OPAL) program has been monitoring the storm more recently using the Hubble Space…

2021年10月26日 Jupiter Rotates Video Credit & Copyright: JL Dauvergne; Music: Oro Aqua (Benoit Reeves) Explanation: Observe the graceful twirl of our Solar System’s largest planet. Many interesting features of Jupiter’s enigmatic atmosphere, including dark belts and light zones, can be followed in detail. A careful inspection will reveal that different cloud layers rotate at slightly different speeds. The famous Great Red Spot is not visible at first — but soon rotates into view. Other smaller storm systems occasionally appear. As large as Jupiter is, it rotates in only 10 hours. Our small Earth, by comparison, takes 24 hours to complete a spin cycle. The featured high-resolution time-lapse video was captured over five nights earlier this month by a mid-sized telescope on an apartment balcony in…
木星─土星大近合：有大红斑参与的盛会
2020年12月23日 Jupiter Meets Saturn: A Red Spotted Great Conjunction Image Credit & Copyright: Damian Peach Explanation: It was time for their close-up. Two days ago Jupiter and Saturn passed a tenth of a degree from each other in what is known a Great Conjunction. Although the two planets pass each other on the sky every 20 years, this was the closest pass in nearly four centuries. Taken early in day of the Great Conjunction, the featured multiple-exposure combination captures not only both giant planets in a single frame, but also Jupiter’s four largest moons (left to right) Callisto, Ganymede, Io, and Europa — and Saturn’s largest moon Titan. If you look very closely, the clear Chilescope image even captures Jupiter’s Great Red Spot. The now-separating…
飞越木星的大红斑
2020年10月19日 A Flight over Jupiter Near the Great Red Spot Image Credit: NASA/JPL-Caltech/SwRI/MSSS; Video Processing & License: Kevin M. Gill; Music: Vangelis Explanation: Are you willing to wait to see the largest and oldest known storm system in the Solar System? In the featured video, Jupiter’s Great Red Spot finally makes its appearance 2 minutes and 12 seconds into the 5-minute video. Before it arrives, you may find it pleasing to enjoy the continually changing view of the seemingly serene clouds of Jupiter, possibly with your lights low and sound up. The 41 frames that compose the video were captured in June as the robotic Juno spacecraft was making a close pass over our Solar System’s largest planet. The time-lapse sequence actually occurred over four…
