After witnessing the array of Northern Lights as far south as Colorado, we discuss how Coronal Mass Ejections (CME) are ...

The Earth's atmosphere is far more reactive to solar activity than scientists previously believed, with the new research showing it can pulse in near-synchronicity with the sun's powerful flares.

That complexity could mean bigger fireworks ahead. With the sunspot now rotating to face Earth, it could pose a threat for ...

A new sunspot forming on the surface of the sun might be about to fling solar flares in our direction. The sunspot, named 3856, is facing Earth and has developed a volatile type of magnetic field ...

On Oct. 3, the sun released the most powerful solar flare this solar cycle, a colossal X9.05 eruption — and it's heading for Earth.

Earth on the Lookout Here on Earth, the most visible effect of the flare was the aurora borealis -- the so-called Northern Lights, often seen over Alaska and Canada at night.

Solar flares, plasma energy and other types of space weather increase in tandem with the number of sunspots. The Earth’s atmosphere then endures bursts of energy and material from the sun's ...

AR 3842 is currently traversing the solar disk and is right in the middle of our field of view; prime position for Earth-directed eruptions. And it emitted another M-class flare just a few hours ...

Powerful solar flare may lead to auroras on Earth. By Clyde Hughes. The European Space Agency shows a golden aurora with a splash of red through the stars during the night of December 13, 2014.

X-class flares can exceed 9, with the largest-ever recorded being an X45 that occurred in 2003. Could a powerful solar flare wipe out life on Earth? Thursday’s flare was much smaller, reaching ...
