木星的大红斑

This April 1, 2018, enhanced-color image of Jupiter’s Great Red Spot was captured by NASA’s Juno spacecraft. The image is a combination of three separate images taken as Juno performed its 12th close flyby of the planet.

The Great Red Spot, a swirling oval of clouds twice as wide as Earth, has been observed on the giant planet for more than 300 years. In 2021, findings from Juno showed that Jupiter’s storms are far taller than expected, with some extending 60 miles (100 kilometers) below the cloud tops and others, including the Great Red Spot, extending over 200 miles (350 kilometers).

Juno is a solar-powered spacecraft that spans the width of a basketball court and makes long, looping orbits around Jupiter. It seeks answers to questions about the origin and evolution of Jupiter, our solar system, and giant planets across the cosmos.

2018年4月1日，NASA朱诺号航天器拍摄了木星大红斑的增强彩色图像。这张照片是朱诺号第12次近距离飞掠木星时拍摄的三张独立照片的组合。

300多年前，人们就在这颗巨大的行星上观测到了大红斑，它是一个漩涡状的椭圆形云层，宽度是地球的两倍。2021年，朱诺号的发现表明，木星的风暴远高于预期，一些风暴延伸到云顶以下60英里（100公里），而其他风暴，包括大红斑，延伸超过200英里（350公里）。

朱诺号是一艘太阳能航天器，其宽度相当于一个篮球场，绕木星绕轨道运行。它寻求木星、太阳系和宇宙中巨行星的起源和演化问题的答案。
