Researchers know cosmic rays originate from the multitude of stars in the Milky Way and other galaxies. The difficulty is tracing the particles to specific sources, because the turbulence of interstellar gas, plasma, and dust causes them to scatter and rescatter in different directions. Researchers developed a simulation model to better understand these and other cosmic ray transport characteristics, with the goal of developing algorithms to enhance existing detection techniques.

Researchers have investigated what happened to a specific kind of plasma - the first matter ever to be present - during the first microsecond of Big Bang. Their findings provide a piece of the puzzle to the evolution of the universe, as we know it today.

An investigation carried out by the astrophysicists questions one of the most interesting findings about the dynamics of the Milky Way in recent years: that the precession, or the wobble in the axis of rotation of the disc warp is incorrect.

The first detailed cross-section of a galaxy broadly similar to the Milky Way reveals that our galaxy evolved gradually, instead of being the result of a violent mash-up. The finding throws the origin story of our home into doubt.
