NASA's IXPE sends first science image

In time for Valentine's Day, NASA's Imaging X-Ray Polarimetry Explorer which launched Dec. 9, 2021, has delivered its first imaging data since completing its month-long commissioning phase.

Bubble with titanium triggers titanic explosions

Scientists have found fragments of titanium blasting out of a famous supernova. This discovery, made with NASA's Chandra X-ray Observatory, could be a major step in pinpointing exactly how some giant stars explode.

Shock waves from stellar explosions take preferential direction

In a paper published in the Astrophysical Journal, a team led by researchers at École Polytechnique have paved the way to unraveling the mystery as to why many supernova remnants that we observe from Earth are axisymmetric ...

How hot are atoms in the shock wave of an exploding star?

A new method to measure the temperature of atoms during the explosive death of a star will help scientists understand the shock wave that occurs as a result of this supernova explosion. An international team of researchers, ...

Astrophysicists explain the mysterious behavior of cosmic rays

A team of scientists from Russia and China has developed a model explaining the nature of high-energy cosmic rays (CRs) in our galaxy. These CRs have energies exceeding those produced by supernova explosions by one or two ...

NuSTAR finds new clues to 'chameleon supernova'

"We're made of star stuff," astronomer Carl Sagan famously said. Nuclear reactions that happened in ancient stars generated much of the material that makes up our bodies, our planet and our solar system. When stars explode ...
