When a solar flare filled with charged particles erupts from the sun, its magnetic fields sometime break a widely accepted rule of physics. The flux-freezing theorem dictates that the magnetic lines of force should flow away in lock-step with the particles, whole and unbroken. Instead, the lines sometimes break apart and quickly reconnect in a way that has mystified astrophysicists. But in a paper published in the May 23 issue of the journal Nature, an interdisciplinary research team led by a Johns Hopkins mathematical physicist says it has found a key to the mystery.

A team of Johns Hopkins astrophysicists using NASA’s Hubble Space Telescope has detected a distant Type Ia supernova, the farthest stellar explosion that can be used to measure the expansion rate of the universe. The supernova is the remnant of a star that exploded 9 billion years ago.
Marc Kamionkowski, considered one of the world’s leading theoretical physicists for his work in large-scale structures and the early history of the universe, will join the faculty in the Henry A. Rowland Department of Physics and Astronomy at The Johns Hopkins University’s Krieger School of Arts and Sciences on July 1. An endowed professor at California Institute of Technology, Kamionkowski has spent much of his career researching astrophysics, cosmology and elementary particle theory.
Johns Hopkins University astrophysicist Charles Bennett and two colleagues today have been awarded this year’s $1 million Shaw Prize in astronomy for groundbreaking research determining the precise age, composition and curvature of the universe.
A team led by Johns Hopkins astrophysicist Charles L. Bennett has won a $5 million National Science Foundation grant – administered through the stimulus act – to build an instrument designed to probe what happened during the universe’s first trillionth of a second, when it suddenly grew from submicroscopic to astronomical size in far less than time than it takes to blink your eye.
