The star at the center of the solar system does more than provide light and warmth. It also acts as the most powerful ...

The Solar Orbiter spacecraft has tracked near-light-speed electrons back to the sun, finding two distinct families generated by solar flares and CMEs.

Solar Orbiter has identified the Sun’s dual “engines” for superfast electrons: explosive flares and sweeping coronal mass ...

The images, captured with the new Daniel K. Inouye Solar Telescope in Hawaii, reveal arcs of hot gas just 10 to 30 miles wide that follow the sun’s magnetic fields. Earlier instruments could only ...

The European Space Agency-led Solar Orbiter mission has split the flood of energetic particles flung out into space from the ...

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 ...

The sun has released several powerful M- and X-class solar flares over the past few days, resulting in radio blackouts around the world.

A solar flare is a burst of radiation: photons of all wavelengths, traveling at the speed of light. Solar flares are closely related to another solar phenomenon called a coronal mass ejection, or CME.

A physicist who has developed a new model that predicts the speed of solar plasma during solar flares has likening it to the path traveled by a thrown baseball.

After more than three weeks without a powerful solar flare, the sun has suddenly ramped up its activity, firing off three ...

The flashes of white light accompanying some solar flares are caused by the sun’s acceleration of electrons to speeds greater than half the speed of light. The phenomenon’s new explanation ...

The strongest solar flare seen in four years erupted from the surface of the sun early Saturday and smacked into our planet’s atmosphere eight minutes later.
