Drifting Clouds Across the Skies of Mars Captured by NASA Rover CuriosityOn December 12, 2021, the navigation camera aboard NASA's Curiosity rover took two 1-second-8-frame images of the Red Planet's atmosphere. Unlike clouds here on Earth, clouds on Mars are very faint in the atmosphere, so it took special imaging techniques to see them. The clouds are also very high, some 80 km (about 50 miles) above the surface. It is extremely cold at this height, which suggests that these are carbon dioxide ice clouds and not water ice clouds (which can be found at lower altitudes). Literally cool.(Images: NASA/JPL-Caltech/York University)#Mars #Clouds #Curiosity #NASA

Bullseye-Shaped Cloud: Concentric Cloud Rings Over the La Palma Volcano in Spain's Canary IslandAn eruption at The Cumbre Vieja volcano created a bullseye-shaped cloud from above. On September 19, 2021, the volcano began erupting and most of the activity has happened on the ground. For nearly two weeks, thick sheets of lava burned through multiple locations on the southwestern part of La Palma.The effects of the eruption had been less dramatic until the Canary Islands Volcanology Institute (INVOLCAN) reported an increase in explosive activity that started on October 2. In the midst of the activity, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured an image of a dense plume of ash streaming south on October 4.The eruption was not energetic enough to inject large amounts of ash and gases into the stratosphere, where they can have strong and lasting effects on weather and climate. However, it was strong enough to produce a rising column of emissions that formed a bullseye-shaped cloud.The cloud was the product of a rising column of superheated ash and gases known as the eruption column. The process is like when a stone ripples through water when dropped into it.#Clouds #BullsEyeCloud #Spain #CanaryIslandImage Credit: NASA
