The solar atmosphere is a turbulent and magnetized environment, with the release of magnetic energy readily manifesting as emission across the electromagnetic spectrum. Solar radio emission dominates the radio sky, with the brightest solar radio bursts generated via the plasma emission process. The emission has a complex frequency-time structure with many features that are yet […]
The European Space Agency’s Mars Express has captured part of Mars’s Mamers Valles, a fascinating valley system speckled with brief, tornado-like whirlwinds known as dust devils.

We’re still in the definition phase of the Habitable Worlds Observatory (HWO), but it seems like every week a new research group comes out with a paper helping to shape what is becoming one of the most important space telescopes of the 2040s. A new paper posted to the arXiv preprint server from a team […]
US astronaut Christina Koch, the first woman to take part in a lunar mission, was named Wednesday the winner of a top Spanish prize for having “helped extend the frontiers of humanity.”

A newly developed method allows researchers to dynamically switch chirality—a particular lack of mirror symmetry—to generate spin currents in semiconductors, researchers from Science Tokyo report. Their approach relies on the reversible insertion and removal of small chiral molecules from the interlayer gaps of a layered, nonchiral semiconductor material using electrochemistry.

Southwest Research Institute (SwRI) is developing electronics and flight software for the NASA/U.S. Geological Survey (USGS) Landsat 10 satellite, which is set to launch in 2031 to collect new and improved Earth observation data. The mission continues NASA’s and USGS’s partnership on the ongoing Landsat program, which has launched nine satellites since 1972 and provided […]
A prototype quantum sensor developed by researchers at Imperial has demonstrated for the first time that a key principle behind next-generation quantum detectors can work under realistic conditions.

An international team of scientists has identified a completely new type of rock from the red planet and, for the first time, discovered the mineral garnet in a Martian sample. The breakthrough offers a rare glimpse into Mars’ ancient past and could help researchers piece together the planet’s 4.5-billion-year geological history. The discovery was made […]
An international research collaboration between the University of Vienna and Lawrence Berkeley National Laboratory in the United States has used machine learning to re-examine one of the most debated signals in astrophysics. The so-called Galactic Center Excess (GCE), a faint, roughly spherical glow of gamma rays at the center of the Milky Way, has fascinated […]
Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an electric voltage appears perpendicular to a current flowing through a material. Unlike its classical counterpart, the nonlinear version can arise even without breaking time-reversal symmetry, and its magnitude is tied to deep geometric properties […]
One well-done gas giant, coming right up! That’s the latest from researchers analyzing NASA’s James Webb Space Telescope observations of HD 80606 b, an exoplanet four times the mass of Jupiter with an extremely elliptical orbit that sweeps close by its sun-like star. The research team is presenting its study and preliminary findings Tuesday at […]
A team of scientists has used NASA’s Goldstone Solar System Radar and the U.S. National Science Foundation Green Bank Telescope (NSF GBT) to carry out the most extensive radar study to date of Europa, the ocean world orbiting Jupiter. By repeatedly “pinging” Europa with 3.5-centimeter (1.4-inch) radio waves between 2011 and 2024, the team measured […]
