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.
Recent news from The Johns Hopkins University
This section contains regularly updated highlights of the news from around The Johns Hopkins University. Links to the complete news reports from the nine schools, the Applied Physics Laboratory and other centers and institutes are to the left, as are links to help news media contact the Johns Hopkins communications offices.
A team of astronomers at The Johns Hopkins University has used data gathered by NASA’s Hubble Space Telescope to spot a supernova that exploded more than 10 billion years ago, breaking the previous record by roughly 350 million years. Nicknamed in a nod to Woodrow Wilson, the 28th president of the United States and a Johns Hopkins alumnus, “SN Wilson” now stands as the farthest known supernova of the type used to measure cosmic distances.
The Department of Physics and Astronomy at The Johns Hopkins University is hosting its 10th annual Physics Fair from 11 a.m. to 5:30 p.m. on Saturday, April 13, coinciding with the annual Spring Fair celebration on the Homewood campus, 3400 N. Charles St. in Baltimore. Events will take place in the Bloomberg Center for Physics and Astronomy, located on the north end of the campus near Homewood Field.
The announcement that researchers are closer than ever to confirming the existence of the Standard Model Higgs boson particle was made possible in part by contributions from physicists at The Johns Hopkins University who are members of one of two teams conducting experiments at the Large Hadron Collider.
As asteroid 2012 DA14 squeaks by Earth, professors at The Johns Hopkins University are available to discuss what we can do to prepare for – or even prevent – such close encounters in the future.
Johns Hopkins astrophysicists Brice Ménard and Charles L. Bennett have been appointed to the Euclid Consortium, the international team of scientists overseeing an ambitious space telescope project designed to probe the mysteries of dark energy and dark matter. NASA, a partner in the mission, recently announced their selection to the research team for Euclid.
They say that a picture is worth a thousand words, and in the case of an image created by astrophysicist Miguel Angel Aragon of The Johns Hopkins University, the adage holds true. His vibrant computer illustration, which won the National Science Foundation’s 2011 Science and Engineering’s Visualization Challenge in the “Informational Posters and Graphics” category, brings to vivid life many dynamic aspects of the universe, spanning 240 million light years.
To improve the next generation of insect-size flying machines, Johns Hopkins engineers have been aiming high-speed video cameras at some of the prettiest bugs on the planet. By figuring out how butterflies flutter among flowers with amazing grace and agility, the researchers hope to help small airborne robots mimic these maneuvers.
