| Scientists demonstrate machine learning tool to efficiently process complex solar data Posted: 06 Jul 2022 10:33 AM PDT Big data has become a big challenge for space scientists analyzing vast datasets from increasingly powerful space instrumentation. To address this, a team has developed a machine learning tool to efficiently label large, complex datasets to allow deep learning models to sift through and identify potentially hazardous solar events. The new labeling tool can be applied or adapted to address other challenges involving vast datasets. |
| Shedding new light on dark matter Posted: 06 Jul 2022 10:32 AM PDT A team of physicists has developed a method for predicting the composition of dark matter -- invisible matter detected only by its gravitational pull on ordinary matter and whose discovery has been long sought by scientists. |
| 8000 kilometers per second: Star with the shortest orbital period around black hole discovered Posted: 05 Jul 2022 01:22 PM PDT A newly discovered star only takes four years to travel around the black hole at the center of our galaxy. |
| Shedding light on comet Chury's unexpected chemical complexity Posted: 05 Jul 2022 08:22 AM PDT Researchers have for the first time identified an unexpected richness of complex organic molecules on a comet. This was achieved thanks to the analysis of data collected during ESA's Rosetta mission at comet 67P/Churyumov-Gerasimenko, also known as Chury. Delivered to the early Earth by impacting comets, these organics may have helped to kick-start carbon-based life as we know it. |
| More dogs in the neighborhood often means less crime, research shows Posted: 05 Jul 2022 06:07 AM PDT In a recent study, researchers found that neighborhoods with more dogs had lower rates of homicide, robbery and, to a lesser extent, aggravated assaults compared to areas with fewer dogs, at least when residents also had high levels of trust in each other. |
| Laser creates a miniature magnetosphere Posted: 30 Jun 2022 05:32 AM PDT A research team realized magnetic reconnection driven by electron dynamics in laser-produced plasmas and measured the pure electron outflows. Their findings will be applied not only to space and astrophysical plasmas, but also to magnetic propulsion and fusion plasmas. |
