2023年5月23日 Jupiter’s Swirls from Juno Image Credit: NASA/JPL-Caltech/SwRI/MSSS; Processing & License: Kevin M. Gill Explanation: Big storms are different on Jupiter. On Earth, huge hurricanes and colossal cyclones are centered on regions of low pressure, but on Jupiter, it is the high-pressure, anti-cyclone storms that are the largest. On Earth, l...
2022年3月13日 Colorful Airglow Bands Surround Milky Way Image Credit & Copyright: Xiaohan Wang Explanation: Why would the sky glow like a giant repeating rainbow? Airglow. Now air glows all of the time, but it is usually hard to see. A disturbance however — like an approaching storm — may cause noticeable rippling in the Earth’s atmospher...

2021年05月30日 Aurora over Clouds Image Credit & Copyright: Daniele Boffelli Explanation: Auroras usually occur high above the clouds. The auroral glow is created when fast-moving particles ejected from the Sun impact the Earth’s magnetosphere, from which charged particles spiral along the Earth’s magnetic field to strike atoms and molecules hi...
