NASA’s Magellan Data Reveals Volcanic Activity on Venus

March 16, 2023
Direct geological evidence of recent volcanic activity has been observed on the surface of Venus for the first time. Scientists made the discovery after poring over archival radar images of Venus taken more than 30 years ago, in the 1990s, by NASA’s Magellan mission. The images revealed a volcanic vent changing shape and increasing significantly in size in less than a year. Scientists study…

Study Finds Ocean Currents May Affect Rotation of Europa’s Icy Crust

March 14, 2023
NASA scientists have strong evidence that Jupiter’s moon Europa has an internal ocean under its icy outer shell – an enormous body of salty water swirling around the moon’s rocky interior. New computer modeling suggests the water may actually be pushing the ice shell along, possibly speeding up and slowing down the rotation of the moon’s icy shell over time. Scientists have known that…

NASA’s Quantum Detector Achieves World-Leading Milestone

March 3, 2023
Quantum computers hold the promise of operating millions of times faster than conventional computers. But to communicate over long distances, quantum computers will need a dedicated quantum communications network. To help form such a network, a device has been developed by scientists at NASA’s Jet Propulsion Laboratory and Caltech that can count huge numbers of single photons – quantum…
