Human missions to Mars are edging closer to reality, but the physics of deep space is not cooperating. Outside Earth’s magnetic cocoon, astronauts would be bombarded by high‑energy particles that can ...

University of Leicester engineers have unveiled a magnetic cloak device that hides or shields an object from external ...

A magnetic cloak works by diverting external magnetic fields so that, to an external observer, the object appears to be absent or invisible. Although this idea ...

For nearly 20 years, physicists and engineers have chased the idea of invisibility. Early efforts focused on hiding objects from light using so-called metamaterials with extreme and often unrealistic ...

The D’Onghia magnetic shielding crew hat, or CREW HaT, is a system that uses electromagnetic coils to deflect cosmic radiation from astronauts. The system consists of: A ring of electrical coils ...

Superconducting magnets, commonly found in MRI scanners, produce stronger, more efficient magnetic fields using smaller and lighter magnets than magnets made using conventional materials such as ...

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s ...

Researchers in Kenya are seeking to reduce the influence of the Geomagnetic field on PV panel performance by replacing aluminum module frames with a steel cage. They have specified they have been ...

A particle detector being prepared for launch Friday aboard space shuttle Endeavour is intended to answer some fundamental questions about physics, but it has a practical side as well — testing a way ...

An aurora glows near Australia in a photo taken from the International Space Station. Auroras are products of charged particles from the sun interacting with Earth's magnetic field. NASA Roughly four ...

Ask scientists why Mars is cold and dead and they'll usually point to the death of its magnetic field some 4.2 billion years ago. Without that protection, solar winds gradually stripped it of most of ...
