Is dark matter's main rival theory dead? The Cassini spacecraft and other recent tests may invalidate MOND
One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up. Galaxies rotate much faster than predicted by applying Newton's law of gravity to their visible matter, despite those ...

Where space weather starts: Self-consistent propagation of flux ropes in realistic coronal simulations
The effects of space weather extend out across our entire solar system, but this is a simulation of where everything starts: the sudden, violent, emergence of a "flux rope" out of the sun's magnetic field and into the solar ...
