Fast radio bursts — intense, milliseconds-long flashes of radio energy from outer space — have puzzled astronomers since they were first spotted in 2007. A single burst can emit as much energy in its brief life as the Sun does in a few days. The great majority of the short-lived pulses originate outside our Milky ...
The famous Pillars of Creation in the Eagle Nebulae — a star nursery — are believed to result from the hydrodynamic instabilities from magnetic fields that form when plasmas are exposed to high-intensity light from neighboring stars. Stretching roughly 4 to 5 light-years, the Pillars of Creation are a fascinating but relatively minor feature of ...
The flipping of the Earth’s magnetic poles is like a person having a heart attack and there are many signs this might be happening right now. If the magnetic field disappears, cosmic rays will bombard our bodies, causing serious diseases such as cancer, and even change our DNA. We would also lose control of satellites, ...
Not counting stories of those rare individuals among us, humans are generally regarded to have only five senses. Sharks, on the other hand, have now been shown to have a sixth: They can make use of the magnetic field of the Earth for navigating across the oceans. For them, it serves as a natural GPS. ...
A dynamo mechanism could explain the incredibly strong magnetic fields in white dwarf stars according to an international team of scientists, including a University of Warwick astronomer. One of the most striking phenomena in astrophysics is the presence of magnetic fields. Like the Earth, stars and stellar remnants such as white dwarfs have one. It ...
A team of scientists, including two physicists at the University of Sussex, has found a way to circumvent a 178-year-old theory, which means they can effectively cancel magnetic fields at a distance. They are the first to be able to do so in a way that has practical benefits. The work is hoped to have ...
Vast rings of electrically charged particles encircle the Earth and other planets. Now, a team of scientists has completed research into waves that travel through this magnetic field, an electrically charged environment, known as the magnetosphere, deepening our understanding of the region and its interaction with our own planet, and opening up new ways to ...
