To commemorate Jupiter’s opposition this year, NASA has released a new ultraviolet image of Jupiter taken by the Hubble Space Telescope, which highlights the details of the Great Red Spot. Jupiter’s Great Red Spot (GRS) is a huge anticyclonic storm that has existed on Jupiter for a long time. It is 16,000 kilometers wide and 1.3 times the width of the Earth. On November 3 this year (Taiwan time), Jupiter will be in opposition. The month before and following is a good time to appreciate the parallel stripes on the surface of this beautiful planet, the Great Red Spot, and the four satellites of Galileo. In order to coincide with Jupiter’s opposition, NASA also released ultraviolet images of Jupiter recently taken by the Hubble Space Telescope. The human eye cannot see ultraviolet light, so the Hubble Telescope photographed Jupiter through three different filters, collected three sets of data at different ultraviolet wavelengths, and synthesized this false-color photo. The original Great Red Spot appears red to the human eye, but appears darker in ultraviolet images. The new images can also help scientists “pull back” Jupiter’s atmosphere and truly observe the upper layers of Jupiter’s interior. For example, using these data to map water clouds deep in Jupiter’s atmosphere can help understand the shape and structure of clouds. The Webb Space Telescope will also turn its attention to Jupiter from time to time. A while ago, it just revealed a new phenomenon of Jupiter’s atmospheric jets and produced extraordinary images of the magnificent scenery of Jupiter (see the picture below). ▲ Jupiter captured by the Webb Space Telescope’s Near Infrared Camera (NIRCam).
