Astronomers unmask cosmic eruptions in nearby galaxies

A brief burst of high-energy light swept through the solar system on April 15, triggering many space-based instruments, including those aboard NASA and European missions. Now, multiple international science teams conclude ...

Magnetic waves explain mystery of Sun's outer layer

The Sun's extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades.

Search for axions from nearby star Betelgeuse comes up empty

The elusive axion particle is many times lighter than an electron, with properties that barely make an impression on ordinary matter. As such, the ghost-like particle is a leading contender as a component of dark matter—a ...

NASA explores solar wind with new view of small sun structures

Scientists have combined NASA data and cutting-edge image processing to gain new insight into the solar structures that create the Sun's flow of high-speed solar wind, detailed in new research published today in The Astrophysical ...

The magnetic fields swirling within the Whirlpool galaxy

Messier objects are some of the most imaged objects in the universe. In part that's because many of them are so visibly appealing. A good example of that is the Whirlpool galaxy, M51, which recently received an even more ...

Scientists streamline process for controlling spin dynamics

Marking a major achievement in the field of spintronics, researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Yale University have demonstrated the ability to control spin dynamics in magnetic ...

The long-range transport of deconfined magnetic hedgehogs

Spintronics is an emerging area of research that aims to develop devices that transmit, process and store information leveraging the intrinsic angular momentum of electrons, known as spin. A key objective of spintronics studies ...
