NASA’s Swift satellite picked up one of the brightest solar flares ever seen — not from our own sun, but a star 16 light-years away. This flare packed the power of thousands of solar flares combined, and a flare of this magnitude from our own sun would have stripped Earth's atmosphere and sterilized the [...]

Now letting the easily unnerved sweat for a bit... Heart in your throat yet? La-la-la.... OK. You've suffered enough.


Astronomers say EV Lacertae is like an unruly child that throws frequent temper tantrums. It's a relatively young star at a few hundred million years of age. But it’s a fast rotating star which generates a strong magnetic field, about 100 times as magnetically powerful as the Sun’s field. The energy stored in its magnetic field powers these giant flares.
