Satellite images capture Hurricane Milton intensifying into Category 5 storm (videos)

NeRD

In the heart of the Gulf of Mexico, a new hurricane is brewing. Hurricane Milton, now having intensified into a Category 5 storm, was caught in incredible space-based imagery from spacecraft such as the U.S. National Oceanic and Atmospheric Administration’s GOES-East satellite.  Hurricane Milton comes just ten days after Hurricane Helene, the deadliest hurricane to hit the United States since Katrina, made landfall in the southeastern U.S.  Milton poses a solid threat to the regions it will impact, and the National Hurricane Center is urging residents of Florida to take…

Sunglint on the Alabama River

NeRD

An astronaut aboard the International Space Station shot this photo of large meanders of the Alabama River while orbiting over the southern United States. The river’s smooth water surface reflects sunlight back toward the astronaut’s camera, producing an optical phenomenon known as sunglint. NASA/Woody Hoburg In this June 26, 2023, photo taken from the International Space Station, sunlight shines off the smooth waters of the Alabama River in a phenomenon known as sunglint. When photographing Earth, astronauts often take advantage of sunglint’s tendency to increase the contrast between water surfaces…

NASA Earth Scientists Take Flight, Set Sail to Verify PACE Satellite Data

NeRD

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) More than 100 scientists will participate in a field campaign involving a research vessel and two aircraft this month to verify the accuracy of data collected by NASA’s new PACE satellite: the Plankton, Aerosol, Cloud, ocean Ecosystem mission. The process of data validation includes researchers comparing PACE data with data collected by similar, Earth-based instruments to ensure the measurements match up. Since the mission’s Feb. 8, 2024 launch, scientists around the world have successfully completed several data validation campaigns; the…

Weird mystery waves that baffle scientists may be ‘everywhere’ inside Earth’s mantle

NeRD

Mysterious zones in the deep mantle where earthquake waves slow to a crawl may actually be everywhere, new research finds. Scientists already knew that ultra-low velocity zones (ULVZs), hover near hotspots — regions of the mantle where hot rock moves upward, forming volcanic island chains such as Hawaii. But mysterious earthquake waves suggest that these features might be widespread. ULVZs, which are located in the lower mantle near the core-mantle boundary, can slow seismic waves by up to 50%. That’s remarkable, said Michael Thorne, a geologist and geophysicist at the University of Utah.…
