usually seen only in more northern regions: the Northern Lights. These beautiful spectral colors which dance through the sky are the result of solar storms on our Sun. When the energy and particles produced by these solar disruptions reach Earth's magnetic field, it reacts...
A series of strong solar flares spewed from the Sun's surface have sent a shockwave of magnetically charged plasma directly at the Earth, known as coronal mass ejections (CMEs). The resulting collision has caused a major disturbance to our own planet's magnetic field....
What happens to the resistance of most common metals as the temperature of the metal increases? What is the most important element for creating a magnetic field, and why? Comic-book superheroes are sometimes able to punch holes through steel walls. If the ultimate shear strength of steel is ...
These stars belong to a class of stars known to harbor many sunspots — dark, planet-size regions that form as the result of intense electromagnetic activity — and that have been tied to other observed superflares. In general, stellar flares occur when magn...
Humans have used the magnetic field of the Earth for navigation since the compass was invented in ancient China. Even the most powerful permanent magnet is not as strong as the strong electromagnets, so their applications are limited, but they still have very widely application, magnets can...
"A preliminary inspection of SOHO/STEREO imagery suggests that the CME will deliver a strong glancing blow to Earth's magnetic field on Jan. 24-25 as it sails mostly north of our planet." Sunday's solar flare was rated an M9-class eruption, which placed it just on the verge of being ...
Solar flares occur when the sun's magnetic field — which creates the dark sunspots on the star's surface — twists up and reconnects, blasting energy outward and superheating the solar surface. X-class solar flares can cause radiation storms in Earth's upper atmosphere and trigger radio black...
28. It was aimed at Earth and generated severe geomagnetic storming whenit blew past the planet less than 24 hours later. A period of relative calm is now expected on the solar surface. But anotherround is possible. The Sun spins once on its axis once every 25 days at its equator, ...
