Prior work using synchronized, geographically spaced radio telescopes, and a radio interferometer, suggests that narrow-bandwidth polarized pulse pair measurements repeatedly falsify a noise-cause hypothesis, given a prior celestial direction of […]

Detecting Planetary Oceans: Application To The Uranus System
The discovery of Europa’s subsurface ocean has spawned a strong desire by the planetary community to return and assess the ocean’s habitability using the magnetic induction signal that Europa generates.
Anomaly Detection and RFI Classification with Unsupervised Learning in Narrowband Radio Technosignature Searches
The search for radio technosignatures is an anomaly detection problem: candidate signals represent needles of interest in the proverbial haystack of radio-frequency interference (RFI).
Ancient Wood Hold Clues About Massive Solar Storms
The Northern Lights were visible much farther south than usual this year, and pictures of the colorful hues filled social media. Now, imagine an aurora hundreds of times brighter – […]
Asteroid Grains Shed Light On The Outer Solar System’s Origins
Tiny grains from a distant asteroid are revealing clues to the magnetic forces that shaped the far reaches of the solar system over 4.6 billion years ago.
Space Weather Forecasts: Monitoring The Daily Variation of Sun-Earth Magnetic Fields Using Galactic Cosmic Rays
The interplanetary magnetic field (IMF) between the Sun and Earth is an extension of the solar magnetic field carried by the solar wind into interplanetary space.
NASA Instruments On ESA Juice Astrobiology Probe Image Earth’s Radiation Belt
From Aug. 19-20, ESA’s (European Space Agency’s) Juice (Jupiter Icy Moons Explorer) mission made history with a daring lunar-Earth flyby and double gravity assist maneuver, a spaceflight first. As the […]
Radio Signatures of Star-Planet Interactions, Exoplanets, and Space Weather
Radio detections of stellar systems provide a window onto stellar magnetic activity and the space weather conditions of extrasolar planets, information that is difficult to attain at other wavelengths.
Influence Of Upstream Solar Wind On Magnetic Field Distribution In The Martian Nightside Ionosphere
This study is led by Postdoctoral researcher Jiawei Gao from IGGCAS. Unlike Earth, Mars lacks a global dipolar magnetic field; the planet does have locally distributed crustal magnetic fields.
Magnetic Fields in a Sample of Planet-hosting M Dwarf Stars from Kepler, K2, and TESS Observed by APOGEE
Stellar magnetic fields have a major impact on space weather around exoplanets orbiting low-mass stars. From an analysis of Zeeman-broadened Fe I lines measured in near-infrared SDSS/APOGEE spectra, mean magnetic […]
