NASA satellites just recorded unexpected ground movement shifting beneath Arizona, and the data has scientists reassessing what they thought they knew about the region. The detection, picked up by advanced orbital instruments, showed surface displacement in an area long considered geologically stable.
Residents of southern Arizona were awakened by a ground movement early Tuesday morning, identified as a magnitude 4.0 earthquake. The tremor, recorded by the U.S. Geological Survey, shook parts of Douglas around 3 a.m. and has drawn renewed attention to the region’s geological activity.For generations, scientists regarded Arizona as one of the most thoroughly studied and stable landscapes in the U…
The bottom of the ocean holds mysteries science has barely begun to map, but when NASA was asked what is really down there, their answer reportedly unsettled even seasoned researchers. Vast trenches plunge deeper than Mount Everest, yet less than twenty percent of the seafloor has ever been directly explored.
In March 2012, filmmaker James Cameron piloted a specially built submarine, the Deep Sea Challenger, to the Challenger Deep, the deepest point in the Mariana Trench. He was the first person to complete that particular dive alone.Waiting for him when he surfaced was Kevin Hand, a NASA astrobiologist from the Jet Propulsion Laboratory. Hand had joined the expedition to study the water and sediment s…
