The technique is being developed to detect venusquakes. A new study details how, in 2019, it made the first balloon-borne detection of a quake much closer to home. Between July 4 and July 6, 2019, a sequence of powerful earthquakes rumbled near Ridgecrest, California, triggering more than 10,000 aftershocks over a six-week period. Seeing an opportunity, researchers from NASA's Jet Propulsi

Carbon dioxide (CO2) emissions from human activities have risen drastically over the last century and a half and are seen as the primary cause of global warming and abnormal weather patterns. So, there has been considerable research focus, in a number of fields, on lowering our CO2 emissions and its atmospheric levels. One promising strategy is to chemically break down, or 'reduce,' CO2 us

Valuable data is flowing rapidly from Earth observing satellites back to the planet, thanks to the most sophisticated laser communication network ever built.

Following recent successful experimentation with Marines at Camp Lejeune, North Carolina, DARPA's Prototype Resilient Operations Testbed for Expeditionary Urban Scenarios (PROTEUS) will transition to the Marine Corps Warfighting Laboratory (MCWL) in Quantico, Virginia. PROTEUS comprises a suite of visual software training and experimentation tools that enables Marines from squad to battali

Modern weather forecasts rely heavily on data retrieved from numerical weather prediction models. These models continue to improve and have advanced considerably throughout more than half a century. However, forecast reliability depends on the quality and accuracy of initialization data, or a sample of the current global atmosphere when the model run is started. This process of bringing su

An educational space technology company in Finland, Arctic Astronautics Ltd., plans to launch this fall a tiny 2-pound satellite made mostly of wood, named Woodsat, as a science experiment and to encourage interest in space. Small launch company Rocket Lab plans to carry the Woodsat into space aboard an Electron rocket lifting off from New Zealand. The goal of the mission is to d

Under the Advanced Shipborne Galileo Receiver Double Frequency (ASGARD) project the technology multinational GMV is collaborating with the defence and security company Saab, to develop a new civil, legislation-compliant, Galileo-signal-using maritime receiver. Co-funded by EUSPA (former GSA), ASGARD aims to boost Galileo take up in maritime transport by developing shipborne e-GNSS (Europea

University of Maryland researchers created the first high-resolution image of an expanding bubble of hot plasma and ionized gas where stars are born. Previous low-resolution images did not clearly show the bubble or reveal how it expanded into the surrounding gas. The researchers used data collected by the Stratospheric Observatory for Infrared Astronomy (SOFIA) telescope to analyze one of

Using data for more than 500 young stars observed with the Atacama Large Millimeter/Submillimeter Array (ALMA), scientists have uncovered a direct link between protoplanetary disk structures - the planet-forming disks that surround stars - and planet demographics. The survey proves that higher mass stars are more likely to be surrounded by disks with "gaps" in them and that these gaps dire

Quasars are very bright, distant and active supermassive black holes that are millions to billions of times the mass of the Sun. Typically located at the centers of galaxies, they feed on infalling matter and unleash fantastic torrents of radiation. Among the brightest objects in the universe, a quasar's light outshines that of all the stars in its host galaxy combined, and its jets and winds sh
