Rosetta spacecraft detects unexpected ultraviolet aurora at a comet

Data from Southwest Research Institute-led instruments aboard ESA’s Rosetta spacecraft have helped reveal auroral emissions in the far ultraviolet around a comet for the first time. At Earth, auroras are formed when charged particles from the Sun follow our planet’s magnetic field lines to the north and south poles. There, solar particles strike atoms and molecules in […]

Russian cosmonaut spots ‘space guests’ amid dazzling auroras in video. They’re not aliens. | Space

Space guests, or how I filmed the new time-lapse. The peak of aurora borealis when passing over the Antarctic in Australia’s longitude, meaning in between them. However, in the video, you will see something else, not only the aurora. pic.twitter.com/Hdiej7IbLU — Ivan Vagner (@ivan_mks63) August 19, 2020 https://www.space.com/russian-cosmonaut-space-guests-video-from-station.html

Aurora, Meet Airglow

“Aurora, Meet Airglow” Two of Earth’s most colorful upper atmospheric phenomena, aurora and airglow, met just before dawn in this photo shot by an astronaut on the International Space Station (ISS). Wavy green, red-topped wisps of aurora borealis appear to intersect the muted red-yellow band of airglow as the ISS passed just south of the Alaskan Peninsula. […]

NASA’s MAVEN Spacecraft Observes Weird Glowing and Pulsing in Mars’ Night Sky – SciTechDaily

This is an image of the ultraviolet “nightglow” in the Martian atmosphere. Green and white false colors represent the intensity of ultraviolet light, with white being the brightest. The nightglow was measured at about 70 kilometers (approximately 40 miles) altitude by the Imaging UltraViolet Spectrograph instrument on NASA’s MAVEN spacecraft. A simulated view of the […]

Space Station Cameras Capture Startling Images Seen here is the Aurora Borealis – AKA The Northern Lights – in all it’s green glowing glory. The gorgeous view perfectly complements the images that have been taken for ages from the ground. For all you Simpsons fans out there, unfortunately there’s no evidence that the ISS astronauts were eating […]
