Explanation: What's that black spot onJupiter? No one is sure. During the latest pass of NASA's Juno around Jupiter,the robotic spacecraft imaged an usually dark cloud feature informally dubbedthe Abyss. Surrounding cloud patterns show the Abyss to be at the center of avortex. Since dark features on Jupiter's atmosphere tend to run deeper thanlight features, the Abyss may really be the deep hole that it appears -- butwithout more evidence that remains conjecture. The Abyss is surrounded by acomplex of meandering clouds and other swirling storm systems, some of whichare topped by light colored, high-altitude clouds. The featured image wascaptured last month while Juno passed only about 15,000 kilometers aboveJupiter's cloud tops. The next close pass of Juno near Jupiter will be in July.
木星上的深渊
木星上的黑点是什么？没有人知道。在NASA朱诺号飞船最近一次飞掠木星期间，拍摄到一个被俗称为深渊的常见暗云结构。周围的云图显示出这个深渊位于旋涡的中心。因为木星大气中的黑暗特征通常比明亮特征位于更深处，所以深渊可能就真的是它所呈现出的深洞样貌，但这只是推测，因为缺乏更多的证据。这个深渊被错综复杂的云团和其他旋涡风暴系统所环绕，其中一些顶部是浅色的高海拔云。这幅特征图像是上个月朱诺号飞掠木星云顶上方仅15,000千米处拍摄的。朱诺号下一次近距离飞掠木星将发生在7月。
