A strategy to realize the efficient resonant absorption of guided water waves

The absorption of water waves is the process through which water waves lose their energy, thus reducing their impact on shores or other solid structures surrounding them. Enabling this absorption process in real-world settings ...

NASA engineers push limits of physics to focus light

A pair of precision-orbiting small satellites will attempt to capture the first views ever of small-scale features near the surface of the sun that scientists believe drive the heating and acceleration of solar wind.

Virtual observatory provides first look at the solar poles

Scientists are turning to artificial intelligence (AI) to view the sun's poles—or at least produce an educated guess of what the sun's poles might look like, since they've never been observed before.

Unlocking the secrets of spin with high-harmonic probes

Deep within every piece of magnetic material, electrons dance to the invisible tune of quantum mechanics. Their spins, akin to tiny atomic tops, dictate the magnetic behavior of the material they inhabit. This microscopic ...

An exo-Neptune beat the odds and kept its atmosphere

As planet-hunting scientists find more and more planets, they've encountered some puzzles. One of them concerns the lack of Neptune-size worlds orbiting close to their stars. Astronomers think that these planets aren't massive ...

Camera 'hack' lets Solar Orbiter peer deeper into sun's atmosphere

Scientists have used Solar Orbiter's EUI camera in a new mode of operation to record part of the sun's atmosphere at extreme ultraviolet wavelengths that has been almost impossible to image until now. This new mode of operation ...

Electron acceleration efficiency during the impulsive phase of a solar flare: X-ray and microwave observations

Solar flares are known to be prolific electron accelerators, yet identifying the mechanism(s) for such efficient electron acceleration in magnetic reconnection events at the sun (and similar astrophysical settings) presents ...

New keen-sighted satellite will view distant stars, assist Webb telescope

NASA's James Webb Space Telescope (JWST), the most powerful telescope ever launched into space, will soon get a new "sidekick"—a small but nimble satellite that borrows its name from a multicolored sea creature.

Scientists discover answer to the mystery of cloudy filters on satellites

There's a mystery happening in some satellites facing the sun, and scientists from the National Institute of Standards and Technology (NIST) and the Laboratory for Atmospheric and Space Physics (LASP) are on the case. The ...
