Solar flares are categorized into five classes: A, B, C, M, and X. Each step up represents a tenfold increase in strength. A-class flares are the weakest and generally go unnoticed on Earth, ...

A list of the most powerful solar flares recorded since 1976 ranks today's flare at number 14, tied with a similar explosion in 1990," wrote Tony Phillips, who runs spaceweather.com, on Thursday.

Solar flare triggers widespread aurora display. A severe geomagnetic storm caused the Northern Lights to appear over an area of Europe and the U.S. as a satellite detected an explosive solar flare.

Recent solar flares, originating from sunspot AR4087, have triggered widespread radio blackouts and raised concerns about Earth's vulnerability to space weather. A FEMA-led drill simulating a ...

At the heart of space weather, reconnection is responsible for powerful solar events, such as solar flares and coronal mass ejections (CMEs), and drives disturbances in Earth's space environment.

Solar storms, characterized by coronal mass ejections (CMEs) and solar flares, release bursts of energized particles and radiation into space. When these particles reach Earth, ...

These solar flares are not a cause for concern for ordinary citizens, but they could interfere with air navigation due to the effect on satellites. Science - English; NASA - English; ...

A powerful solar flare hit on May 30 or 31, and it’s sending a huge wave of energy our way. This might trigger a G4 geomagnetic storm around June 1 or 2, which could bring the Northern Lights as ...

You need a solar telescope with a built-in or attachable filter, one that meets the ISO 12312-2 safety standard. This standard ensures that no more than 0.0032% of the sun's dangerous rays meet ...

Astronomers have revealed new research showing that millions of new solar system objects are likely to be detected by a brand-new facility, which is expected to come online later this year.
