The agency says the solar flare, a powerful burst of energy from the sun, peaked at 4:06 a.m. on Sunday morning. The image of the phenomenon was captured by the Solar Ultraviolet Imager (SUVI) ...

Scientists have confirmed a 19-year-old theory on solar flare formation by observing “slip-running” reconnections in the ...

The surprising source of the repeating burst has baffled astronomers, who haven't considered that regions in which no stars are forming could produce such a radio flare. Start the day smarter.

A big burst of brightness suddenly popped up ... The team spied five to six big flares a day as well as smaller flashes of light in between. “Flares are expected to happen in essentially ...

A blast of radio waves from the outskirts of an ancient galaxy challenges theories about what creates such bursts.

it triggers a massive thermonuclear explosion that releases an intense burst of X-ray radiation. Another theory is that it could be a rare, giant flare from a distant magnetar—neutron stars with ...

Specifically, turbulent fluctuations within the disk can compress plasma (a hot, electrically charged gas) to cause a temporary burst of radiation. Yusef-Zadeh likens the event to a solar flare.
