Dallol Hydrothermal Field (Ethiopië)

Het hydrothermale gebied Dallol ten noordoosten van de Erta Ale Range bevindt zich in een van de laagste en heetste gebieden van de Danakil Depression in Ethiopië. De Dallolkraters zijn de bekende, laagste bovengrondse vulkanische openingen op aarde. Ze bevinden zich op 48 meter onder de zeespiegel. Zoute warmwaterbronnen met een rijk kleurenpalet kenmerken het gebied. Tussen de witte zoutafzettingen vinden we hete, gele sulfervelden.

Volgens mij kon je ook wel eens gewoon oplossen als je daar in valt 🙂

als je op Google Earth kijkt is het niet zo´n grote plas en -op GE- zijn de kleuren stukken doffer maar lijkt me ook link om daar rond te lopen -o.i.d.-

Mt. Etna Lava Plume

Explanation: Mt. Etna has been erupting for hundreds of thousands of years. Located in Sicily, Italy, the volcano produces lava fountains over one kilometer high. Mt. Etna is not only one of the most active volcanoes on Earth, it is one of the largest, measuring over 50 kilometers at its base and rising nearly 3 kilometers high. Pictured in mid-March, a spectacular lava plume erupts upwards, dangerous molten volcanic bombs fly off to the sides, while hot lava flows down the volcano's exterior. The Earth's rotation is discernable on this carefully time, moon-lit, long duration image as star trails.

Ancient Ogunquit Beach on Mars
Image Credit: NASA, JPL-Caltech, MSSS;
Explanation: This was once a beach -- on ancient Mars. The featured 360-degree panorama, horizontally compressed, was taken by the robotic Curiosity rover currently exploring the red planet. Named Ogunquit Beach after its terrestrial counterpart, evidence shows that at times long ago the area was underwater, while at other times it was at the edge of an ancient lake. The light peak in the central background is the top of Mount Sharp, the central feature in Gale Crater where Curiosity has been deployed. Curiosity is slowly ascending Mount Sharp. Portions of the dark sands in the foreground have been scooped up for analysis. The light colored bedrock is composed of sediment that likely settled at the bottom of the now-dried lakebed. The featured panorama (interactive version here) was created from over 100 images acquired in late March and seemingly signed by the rover on the lower left. Currently, Curiosity is carefully crossing deep megaripples of dark sands on its way to explore Vera Rubin Ridge.

Big Dipper Above and Below Chilean Volcanoes

Explanation: Do you see it? This common question frequently precedes the rediscovery of one of the most commonly recognized configurations of stars on the northern sky: the Big Dipper. This grouping of stars is one of the few things that has likely been seen, and will be seen, by every generation. The Big Dipper is not by itself a constellation. Although part of the constellation of the Great Bear (Ursa Major), the Big Dipper is an asterism that has been known by different names to different societies. Five of the Big Dipper stars are actually near each other in space and were likely formed at nearly the same time. Connecting two stars in the far part of the Big Dipper will lead one to Polaris, the North Star, which is part of the Little Dipper. Relative stellar motions will cause the Big Dipper to slowly change its configuration over the next 100,000 years. Pictured in late April, the Big Dipper was actually imaged twice -- above and below distant Chilean volcanoes, the later reflected from an unusually calm lagoon.

Toch raar om iets als Grote beer, Big Dipper te noemen... Overigens, de weerspiegeling in het water is beter herkenbaar voor ons als de sterren zelf boven de bergtoppen 🙂

Dat ziet er mooi uit.
Tjonge jonge wel een licht vervuiling dat hele west europa 😉

Lightning Storm Moves Across the USA
Image Credit: NOAA, NASA, Lockheed Martin, GOES-16, GLM
Explanation: Watch a huge lightning storm move across the eastern USA. The huge storm caused much damage and unfortunately some loss of life for people in its path. Seen from space, the lightning is seen as momentary flashes in the featured time-lapse video recorded last month by the Geostationary Lightning Mapper (GLM) aboard the GOES-16 satellite. The outline of North America is most evident during the day, while the bright lightning strikes are most evident at night. Inspection of the video shows that much of the lightning occurred at the leading edge of the huge tail of the swirling storm. Because lightning frequently precedes a storm's most violent impact, lightning data from GLM holds promise to help reduce the harm to humans from future storms.
