Juno detects Jupiter's highest-energy ions

Jupiter's planetary radiation environment is the most intense in the solar system. NASA's Juno spacecraft has been orbiting the planet closer than any previous mission since 2016, investigating its innermost radiation belts ...

Ultra-high-energy gamma rays originate from pulsar nebulae

The discovery that the nebulae surrounding the most powerful pulsars are pumping out ultra-high-energy gamma rays could rewrite the book about the rays' galactic origins. Pulsars are rapidly rotating, highly magnetized collapsed ...

Water splitting for solar energy conversion

In order to enable large-scale hydrogen production using solar energy, particulate photocatalysts are being researched as a simple and cost-effective solution to splitting water into hydrogen and oxygen. It is necessary to ...

Stellar eggs near galactic center hatching into baby stars

Astronomers found a number of baby stars hiding around the center of the Milky Way using the Atacama Large Millimeter/submillimeter Array (ALMA). Previous studies had suggested that the environment there is too harsh to form ...

NASA's Swift helps tie neutrino to star-shredding black hole

For only the second time, astronomers have linked an elusive particle called a high-energy neutrino to an object outside our galaxy. Using ground- and space-based facilities, including NASA's Neil Gehrels Swift Observatory, ...
