The sun is capable of firing off an incredibly powerful superflare that could wreak havoc on Earth’s technology-dependent society, a new study suggests. The same basic processes drive the “normal” flares of high-energy radiation emitted by the sun and superflares blasted out by faraway stars, which can be thousands of times more powerful, researchers found. […]


Solar flares aren’t just fearsome displays of power capable of sending Earth’s technology back 200 years. They are also peculiar stellar phenomena that generate so much energy, they make particles move at nearly the speed of light. To that end, they may be models of future space travel. But how exactly they work that kind […]


The sun has fully “flipped upside down”, with its north and south poles reversed to reach the midpoint of Solar Cycle 24, Nasa has said. Now, the magnetic fields have once again started moving in opposite directions to begin the completion of the 22 year long process which will culminate in the poles switching once […]
