红外木星，喷发木卫一

为了庆祝世界空间周，我们将在2007年新地平线号探测器飞过木星时拍摄木星的图片。如果木星看起来和你以前看到的有点不同，那是因为它是用太空探测器的近红外成像光谱仪成像的。在这张假彩色图像中，木星的高海拔云层，就像它的大红斑一样，被渲染成白色，而较深的云层则呈现红色。这颗行星最深处的卫星木卫一在一次频繁的火山喷发中被拍摄到了一张真彩色合成图像。仔细观察就会发现，在被喷射到月球稀薄大气中的蓝白相间的粒子羽流下，熔岩发出红光。

To celebrate World Space Week, we're featuring this montage of images of Jupiter courtesy of the New Horizons probe's flyby of the planet in 2007. If Jupiter looks a little different than you're used to seeing, it's because it was imaged using the space probe's near-infrared imaging spectrometer. In this false-color image, Jupiter's high-altitude clouds, like its stormy Great Red Spot, are rendered white, while deeper cloud formations take on reddish hues. The planet's innermost moon, Io, is captured in a true-color composite image during one of its frequent volcanic eruptions. A close look will show lava is glowing red beneath the blue and white plume of particles being ejected into the moon's thin atmosphere.
