7+ hour, 54+ min ago  (287+ words) The decision to move ahead with Sedna-3 and Sedna-4 follows growing demand for satellite-delivered maritime data from customers that rely on timely information for operations and safety at sea. AAC Clyde Space said the new satellites are intended to add…...

4+ day, 10+ hour ago  (476+ words) Los Angeles CA (SPX) Feb 18, 2026 - Gravity feels stable in everyday life, but its strength varies across the surface of the planet, and it is weakest beneath Antarctica after accounting for Earth rotation. These subtle variations ari Slow mantle flow built…...

5+ day, 10+ hour ago  (663+ words) The team reports that meteorite impact fluxes on the Moon's near and far sides are essentially consistent over time. This finding supports the use of a unified global lunar cratering chronology and contradicts earlier suggestions that the far side experienced…...

1+ week, 3+ day ago  (154+ words) "Our results show that even during Mars' most recent volcanic period, magma systems beneath the surface remained active and complex," says Bartosz Pieterek of Adam Mickiewicz University. "The volcano did not erupt just once-it evolved over time as conditions in…...

1+ week, 5+ day ago  (187+ words) The representation separates space, time, and measured parameters into distinct axes, then aligns them in a unified grid that can accommodate a wide range of satellite and in situ measurements collected at different resolutions and times. By treating each dimension…...

2+ week, 1+ day ago  (659+ words) A new study by MIT researchers suggests some early forms of life may have evolved the ability to use oxygen hundreds of millions of years before the GOE. The findings may represent some of the earliest evidence of aerobic respiration…...

2+ week, 1+ day ago  (335+ words) Extended periods of reduced geomagnetic shielding likely influenced atmospheric chemistry, climate processes and the evolution of living organisms, according to co-author Peter Lippert, an associate professor in the U Department of Geology and Geophysics. The results appear in Nature Communications…...

2+ week, 1+ day ago  (367+ words) In the model, fractured zones deep in the crust are assumed to contain high-temperature, high-pressure water that may be in a supercritical state. These fluid-filled regions behave like capacitors, electrically coupled both to the ground surface above and to the…...

3+ week, 2+ day ago  (277+ words) Researchers have now shown that EMIT can find plastic compounds in landfills and in extensive manmade structures such as greenhouses. However, detecting plastic after it enters the ocean is far more difficult because seawater absorbs much of the infrared light…...
