Rising concentrations of carbon dioxide in the upper atmosphere will change the way geomagnetic storms impact Earth, with potential implications for thousands of orbiting satellites, according to new research led by NSF NCAR. The upper atmosphere's density will be lower compared with present-day geomagnetic storms, although the temporary rise from baseline to peak during a multiday storm will be more pronounced.
The SETI Institute awarded the Davie Postdoctoral Fellowship for AI/ML-driven exoplanet discovery to Isabel Angelo. Machine learning is changing the way we search for exoplanets and making it possible to discover patterns in massive datasets. Angelo’s research will refine and expand ML-driven pipelines for detecting exoplanets, and she will work with SETI Institute researcher Dr. Vishal Gajjar and his team and collaborators at the SETI Institute and IIT Tirupati in India.
The project will enhance supervised Convolutional Neural Network (CNN) architectures and integrate anomaly-detection techniques to identify subtle or unconventional exoplanet candidates hidden in massive datasets. These could include ringed or disintegrating worlds, exocomets, complex multi-planet systems and possibly signs of alien megastructures.
EIRSAT-1, Ireland’s first satellite, has successfully tested an advanced onboard control system that allows it to orient itself accurately in space. The breakthrough was achieved using a payload called Wave-Based Control (WBC), a software platform designed by a team at UCD School of Mechanical and Materials Engineering to test new satellite manoeuvring techniques while in orbit.
