月亮与冒烟圈的埃特纳火山
在照片的底部，一条黑色的山脊横过前景。烟雾在山脊周围升起，仔细观察可以发现其中一些烟雾形成了烟圈。背景呈淡红色，左上方可见新月。有关更多详细信息，请参阅说明。

2023年8月15日 A Triply Glowing Night Sky over Iceland Credit & Copyright: Wioleta Gorecka; Text: Natalia Lewandowska (SUNY Oswego) Explanation: The Sun is not the quiet place it seems.

陨石坑农场
影像来源：NASA/JPL 在一张名为“陨石坑农场”的麦哲伦图片中，我们看到了火山活动和撞击坑的奇特分层。 这张金星表面的三维透视图显示了三个撞击坑。图像的中心位于拉维尼亚平原西北部，大约南纬27度，东经339度。 科学家/工程师对这张图片的看法： “我记得当我第一次看到麦哲伦任务初期的新闻稿图片时，该地区被非正式地称为’陨石坑农场’。我可以从那张照片中看到金星有一些很奇怪的地方。即使这张照片是90年代初拍摄，但是现在看起来还是很奇怪。陨石坑农场的图像显示了这些看起来非常原始的陨石坑，它们叠加在火山背景上，完全没有覆盖到陨石坑的边缘。 至少在这张照片中，当金星被陨石坑覆盖时，所有这些发光的火山活动不知何故停止了。当然，这不应该是一个合理的行星历史；火山活动应该停止，陨石坑应该继续存在——...
埃特纳火山上空的光柱
2021年11月15日 Light Pillar over Volcanic Etna Image Credit & Copyright: Giancarlo Tinè Explanation: What happening above that volcano? Something very unusual — a volcanic light pillar. More typically, light pillars are caused by sunlight and so appear as a bright column that extends upward above a rising or setting Sun. Alternatively, other light pi...
火山上空的大近合
2020年12月20日 A Volcanic Great Conjunction Image Credit & Copyright: Francisco Sojuel Explanation: Where can I see the Great Conjunction? Near where the Sun just set. Directionally, this close passing of Jupiter and Saturn will be toward the southwest. Since the planetary pair, the Sun, and the Earth are nearly in a geometric straight line, the planets wi...

2020年10月27日 Venusian Volcano Imagined Illustration Credit: NASA, JPL-Caltech, Peter Rubin Explanation: What would an erupting volcano on Venus look like? Evidence of currently active volcanoes on Venus was announced earlier this year with the unexplained warmth of regions thought to contain only ancient volcanoes. Although large scale images of Venus have be...
