Changes in atmospheric density after sunset can cause hot pockets of gas called 'plasma bubbles' to form over the Earth's equator, resulting in communication disruptions between satellites and the Earth. New AI models are now helping scientists to predict plasma bubble events and create a forecast. The work was presented this week at the National Astronomy Meeting (NAM 2022) by Sachin Redd

Air quality planning agencies in the U.S. Great Lakes region now include high-resolution NASA satellite data and near real-time Earth observations in their ozone pollution assessments. Creating models that accurately predict the complex lake and land breezes along Lake Michigan's shoreline is very difficult, but it's also vital to understanding how ozone pollution circulates in the region.

Many people are familiar with the hole in the ozone layer over Antarctica, but what is less well known is that occasionally, the protective ozone in the stratosphere over the Arctic is destroyed as well, thinning the ozone layer there. This last happened in the spring months of 2020, and before that, in the spring of 2011. Each time the ozone layer has been thinned out, climate researchers

Over the next two weeks, a handful of NASA scientists will be living very different lives from the rest of us: they will board a research plane in Greenland alongside laser instruments to help calibrate NASA's space-based measurements of Arctic ice. The ice researchers and instrument scientists will board NASA's Gulfstream V jet and fly out of Thule Air Base in northwestern Greenland to he

Researchers have shown that a quantum-inspired technique can be used to perform lidar imaging with a much higher depth resolution than is possible with conventional approaches. Lidar, which uses laser pulses to acquire 3D information about a scene or object, is usually best suited for imaging large objects such as topographical features or built structures due to its limited depth resolution.

Deep below the Black Hills of South Dakota in the Sanford Underground Research Facility (SURF), an innovative and uniquely sensitive dark matter detector - the LUX-ZEPLIN (LZ) experiment, led by Lawrence Berkeley National Lab (Berkeley Lab) - has passed a check-out phase of startup operations and delivered first results. The take home message from this successful startup: "We're ready and

Space Systems Command (SSC) officials and other agencies involved in Space Domain Awareness (SDA) will meet with traditional and non-traditional space industry professionals July 28 in Colorado Springs to exchange ideas and methods to execute SDA missions at the next SSC Industry Day. To register, visit the SSC Front Door webpage. "Strengthening partnerships with industry and having valuab

SpaceX on Sunday launched 53 Starlink satellites after the company's Dragon cargo craft carrying crew supplies and scientific experiments docked with the International Space Station on Saturday. The Starlink satellites were launched to orbit from a Falcon 9 rocket at the Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida at 10:20 a.m. Sunday. It was the 31st

A network in which data transmission is perfectly secure against hacking? If physicists have their way, this will become reality one day with the help of the quantum mechanical phenomenon known as entanglement. For entangled particles, the rule is: If you measure the state of one of the particles, then you automatically know the state of the other. It makes no difference how far away the entangl

Satellite navigation has transformed the way people live and work, but because the majority of us access it via our smartphones, the actual precision of positioning that we end up with has plenty of room for improvement. ESA led a project investigating if an array antenna approach borrowed from satellite design might deliver enhanced positioning for future smartphones, tablets, drones and other mass-market devices.
