木星上的深渊

说明:木星上的黑点是什么?没有人能确定。在美国航天局的朱诺号宇宙飞船最近一次飞掠木星期间,拍摄到一个被俗称为深渊的暗云结构。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结构往往比明亮结构位于更深处,所以深渊可能真的是它所呈现出的深洞,但是缺乏更多的证据,仍只是推测。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。这幅特征影像拍摄于上个月朱诺号飞掠木星云顶上方仅15,000千米处。朱诺号下一次近距离飞掠木星将发生在7月。

Explanation: What’s that black spot on Jupiter? No one is sure. During the latest pass of NASA’s Juno around Jupiter, the robotic spacecraft imaged an usually dark cloud feature informally dubbed the Abyss. Surrounding cloud patterns show the Abyss to be at the center of a vortex. Since dark features on Jupiter’s atmosphere tend to run deeper than light features, the Abyss may really be the deep hole that it appears — but without more evidence that remains conjecture. The Abyss is surrounded by a complex of meandering clouds and other swirling storm systems, some of which are topped by light colored, high-altitude clouds. The featured image was captured last month while Juno passed only about 15,000 kilometers above Jupiter’s cloud tops. The next close pass of Juno near Jupiter will be in July.
