How Superstorm Gannon Squeezed Earth’s Plasmasphere To One-fifth Its Size
A geomagnetic superstorm is an extreme space weather event that occurs when the Sun releases massive amounts of energy and charged particles toward Earth. These storms are rare, occurring about […]

Impact of a High Magnetic Field on the Orientation of Gravitactic Unicellular Organisms
The gravity-dependent behavior of Paramecium biaurelia and Euglena gracilis have previously been studied on ground and in real microgravity.
![Maximum predicted emission frequency and radio flux density for known exoplanets (triangle symbols; data from [8]). The uncertainties on the predictions are estimated to one order of magnitude for the flux density and a factor of 2-3 for the emission frequency12. The sensitivities for the ground-based (UTR-2, LOFAR, NenuFAR, SKA-Low, VLA, GMRT) and space-based (FARSIDE, LCRT, FARVIEW ) radio telescopes are labeled (for 10 min of integration time and a bandwidth of 24 MHz). The FARVIEW and LCRT sensitivity curves are taken from [19] and [2], respectively. The LuSEE-Night sensitivity curve is averaged over the entire two-year mission and includes post-processing using a LombScargle periodogram (see text for details). The possible detection of τ Boo b from LOFAR23 is shown as a red star.

Can A Convecting Magma Ocean Offer A Solution To The Puzzling Case Of Core Convection In Early Earth?
Convective flow in Earth’s iron-rich liquid core drives self-sustained dynamo action, generating Earth’s magnetic field, which is strongest among all terrestrial planets of the solar system.

Numerical Simulations Of The Interaction Between The Stellar Magnetic Field And A Planet
Kepler and TESS observations led to the discovery of many close-in super Earths, including some with ultra-short orbital periods (≲1 day).
![Stokes I (top), polarized intensity (PI) (middle) and polarization fraction (PF) (bottom) at 0.87, 1.3, 2.1 and 2.7 mm wavelengths plotted against right ascension (Δα) and declination (Δδ). Polarization vectors are also shown on the PI and PF images. The Stokes I and PI are converted to the brightness temperature (TB) by assuming the Rayleigh–Jeans approximation. The PF and polarization vectors are plotted where the polarized intensity is detected above the 3σ noise level. Contours on the PI and PF images indicate the brightness temperatures of the Stokes I emission of [0.1, 1, 10, 20] K for 0.87 mm, [0.1, 1, 5, 10, 20] K for 1.3 mm, [0.1, 1, 5, 9] K for 2.1 mm and [0.06, 0.3, 1, 3] K for 2.7 mm. The resolution (beam size) is shown as a small ellipse in the lower left corner of each panel. -- NAOJ](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/02/Stellar-Magnetic-Fingerprints.png?resize=1200%2C719&ssl=1)
