A slope of volcano is pictured with red glowing lava running down its side. A dark starry sky is in the background. Up into the sky a red column is visible. Please see the explanation for more detailed information.
一座火山的山坡上，炽热的红色熔岩沿着山体流淌而下。背景是一片黑暗的星空，天空中还可以看到一根红色的光柱。有关更多详细信息，请参阅说明。

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9月15日 Venus, Moon, and the Smoking Mountain Image Credit & Copyright: Luis Miguel Meade Rodríguez Explanation: Venus has returned as a brilliant morning star. From a window seat on a flight to Mexico City, the bright celestial beacon was captured just before sunrise in this astronomical snapshot, taken on September 12. Venus, at the upper right, shared the early predawn skies with an old crescent Moon. Seen from this stratospheric perspective, both mountain peaks and clouds appear in silhouette along a glowing eastern horizon. The dramatic, long, low cloud bank was created by venting from planet Earth’s active volcano Popocatépetl. Tomorrow’s picture: Fire over Ice 金星、月亮与冒烟的山 影像提供与版权: Luis Miguel Meade Rodríguez 说明: 金星以明亮的晨星之姿回归了。9月12日即将日出前的清晨，在前往墨西哥城的航班上，从靠窗的座位拍下了这幅记录了此明亮天体的影像。影像里，右上方的金星与蛾眉残月分享了黎明前的天空。从这个平流层的视角看出去，山峰和云朵都以剪影之姿出现在明亮的东方地平线附近。其中，低矮壮观的长云，是由地球上的波波卡特佩特活火山（Popocatépetl）所喷出的烟尘。 明日的图片: Fire over Ice
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. It expels an unsteady stream of energetic electrons and protons known as the solar wind. These charged particles deform the Earth’s magnetosphere, change paths, and collide with atoms in Earth’s atmosphere, causing the generation of light in auroras like that visible in green in the image left. Earth itself is also geologically active and covered with volcanoes. For example, Fagradalsfjall volcano in Iceland, seen emitting hot gas in orange near the image center. Iceland is one of the most geologically active places on Earth. On the far right is the Svartsengi geothermal power plant which creates the…
2023年4月4日 Olympus Mons: Largest Volcano in the Solar System Image Credit: ESA, DLR, FU Berlin, Mars Express; Processing & CC BY 2.0 License: Andrea Luck Explanation: The largest volcano in our Solar System is on Mars. Although three times higher than Earth’s Mount Everest, Olympus Mons will not be difficult for humans to climb because of the volcano’s shallow slopes and Mars’ low gravity. Covering an area greater than the entire Hawaiian volcano chain, the slopes of Olympus Mons typically rise only a few degrees at a time. Olympus Mons is an immense shield volcano, built long ago by fluid lava. A relatively static surface crust allowed it to build up over time. Its last eruption is thought to have been about 25 million years…
2023年1月28日 Comet ZTF over Mount Etna Image Credit & Copyright: Dario Giannobile Explanation: Comet-like plumes are blowing over the volcanic peaks of Mount Etna in this wintry mountain-and-skyscape from planet Earth. The stacked and blended combination of individual exposures recorded during the cold night of January 23, also capture naked-eye Comet ZTF just above Etna’s snowy slopes. Of course increasing sunlight and the solar wind are responsible for the comet’s greenish coma and broad dusty tail. This weekend Comet ZTF is dashing across northern skies between north star Polaris and the Big Dipper. From a dark site you can only just spot it as a fuzzy patch though. That’s still an impressive achievement if you consider you are gazing at a visitor from the distant…
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 pillars — some quite colorful — have been recorded above street and house lights. This light pillar, though, was illuminated by the red light emitted by the glowing magma of an erupting volcano. The volcano is Italy’s Mount Etna, and the featured image was captured with a single shot a few hours after sunset in mid-June. Freezing temperatures above the volcano’s ash cloud created ice-crystals either in cirrus clouds high above the…
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 will be seen to set just where the Sun had set — from every location on Earth. When can I see the Great Conjunction? Just after sunset. Since the two planets are so near the Sun directionally, they always appear in the sky near the Sun, but can best be seen when the Earth blocks the Sun but not the planets: sunset. Soon thereafter, Jupiter and Saturn will also…
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 been taken with radar, thick sulfuric acid clouds would inhibit the taking of optical light vistas. Nevertheless, an artist’s reconstruction of a Venusian volcano erupting is featured. Volcanoes could play an important role in a life cycle on Venus as they could push chemical foods into the cooler upper atmosphere where hungry microbes might float. Pictured, the plume from an erupting volcano billows upwards, while a vast lava field covers part of the hot…
