This view from NASA’s Juno spacecraft captures colorful, intricate patterns in a jet stream region of Jupiter’s northern hemisphere known as “Jet N3.” Jupiter’s cloud tops do not form a simple, flat surface. Data from Juno helped scientists discover that the swirling ba […]
木星让位，土星成为新的卫星之王。 卡耐基科学研究所（Carnegie Institution for Science）的斯科特•S•谢泼德（Scott S. Sheppard）领导的研究小组发现了环绕土星的20颗新卫星。这使得这颗带有光环的行星的卫星总数达到了82颗，超过了木星的79颗。国际天文协会小行星中心（International Astronomical Union’s Minor Planet Centre）于2019年10月7日宣布了这一发现。 新发现的每颗卫星直径均约5公里（3英里）。其中有17颗卫星的运行轨道是反向的，即逆行卫星，这意味着它们的运行方向与土星自转方向相反。剩余三

This new Hubble Space Telescope view of Jupiter, taken on June 27, 2019, reveals the giant planet’s trademark Great Red Spot, and a more intense color palette in the clouds swirling in Jupiter’s turbulent atmosphere than seen in previous years. The colors, and their changes, provide impo
2019 August 7 Jupiter Engulfed and the Milky Way Image Credit & Copyright: Mohammad S. Hayati Explanation: This is a good month to see Jupiter. To find our Solar System’s largest planet in your sky, look toward the southeast just after sunset — Jupiter should be the brightest object
NASA’s Juno spacecraft captured this view of an area within a Jovian jet stream showing a vortex that has an intensely dark center. Nearby, other features display bright, high altitude clouds that have puffed up into the sunlight. The color-enhanced image was taken at 12:55 a.m. PDT (3:55 a.m. EDT)
这张令人惊叹的木星北半球风暴的图片是由美国宇航局的朱诺号飞船在近距离飞越这颗气态巨行星时拍摄的。在木星圆盘的右侧，可以看到一些在高空的明亮的白云。 “朱诺号”于2019年5月29日美国东部时间凌晨3点52分至凌晨4点03分拍摄了这四张用来产生这张彩色增强图的图片，当时“朱诺号”正在对木星进行第20次科学探测。在拍摄这些照片时，这艘宇宙飞船位于木星云层上方11,600英里(18,600公里)至5,400英里(8,600公里)之间，位于北纬59度至34度之间。 公民科学家凯文·M·吉尔利用宇宙飞船JunoCam成像仪的数据制作了这幅图像。公众可以通过https://missionjuno.swri
2019 June 10 木星的深渊 图像来源：NASA, Juno, SwRI, MSSS; Processing & License: Gerald Eichstädt & Sean Doran 说明：木星上的那个黑点是什么?没人能肯定。在美国国家航空航天局(NASA)的“朱诺号”(Juno)最近一次环绕木星时，这艘机器人宇宙飞船拍摄到了了一个通常被称为“深渊”(Abyss)的黑云特征。周围的云图显示深渊位于漩涡的中心。由于木星大气层较暗的特征往往比较亮的特征更深入，深渊可能真的是它所出现的深洞——但这并没有更多的证据，这仍然仅是猜测。这个深渊被错综复杂的云团和其他漩涡风暴
