Cosmic rays, born from powerful events like exploding stars, are a key but elusive part of a galaxy’s interstellar medium. Today’s paper combines gamma-ray, X-ray, infrared, and radio observations of M82 to untangle how cosmic rays and magnetic fields shape its energetic core.
Using data from NASA’s Juno mission, the authors of today’s paper have discovered plasma conditions so peculiar they don’t exist anywhere else we’ve ever explored in the solar system, giving rise to a whole new type of plasma wave mode.
Pieces flying left and right and a rock spinning around in its orbit – Take a look at the consequences of shooting an asteroid with a spacecraft in today’s paper!
It is generally believed that the X-ray emission from cold-core clusters comes from hot gas, where there is a delicate balance between gas cooling and feedback from active galactic nuclei. This paper explores another possibility: are these X-rays simply an illusion of inverse Compton scattering by cosmic rays?
In today’s classic 1956 paper, the authors measure a stellar diameter and kick off a debate about the quantum nature of light!
The Infinity Galaxy might be home to a newborn supermassive black hole that formed directly from a gas cloud instead of a star. Could this help reveal how these objects formed in the early universe?
