NASA's IXPE helps researchers maximize 'microquasar' findings

The powerful gravity fields of black holes can devour whole planets' worth of matter—often so violently that they expel streams of particles traveling near the speed of light in formations known as jets. Scientists understand ...

Stabilizing precipitate growth at grain boundaries in alloys

Materials are often considered to be one phase, but many engineering materials contain two or more phases, improving their properties and performance. These two-phase materials have inclusions, called precipitates, embedded ...

Search for heavy bosons sets new limits

Since discovering the Higgs boson in 2012, the ATLAS Collaboration at CERN has been working to understand its properties. One question in particular stands out: why does the Higgs boson have the mass that it does? Experiments ...

Astronomers discover a 'changing-look' blazar
