Considered our solar system's largest explosive events, solar flares can sometimes be as strong as a billion hydrogen bombs. Those with enough energy output to rank as an X-class have the potential to ...

Major solar flare causes shortwave radio disruptions across North America A powerful M-class solar flare erupted from the sun on June 15, triggering radio blackouts across North America. The flare, ...

In the span of two days last week, the sun released two strong solar flares — meaning the solar system experienced its most powerful explosions which can cause some communications blackouts on Earth, ...

The sun unleashed two huge flares early Wednesday, one day after a NASA observatory captured a dramatic photo of a separate solar flare. The back-to-back eruptions included the strongest of the year ...

The M-class flare was accompanied by a coronal mass ejection currently forecast to land Earth with a glancing blow on June 18. An Earth-facing sunspot has turned into a prolific flare factory, firing ...

Research by university scientists suggests that solar flares may be far hotter than previously believed, offering new insights into the Sun’s behavior. The findings, recently published in the ...

The sun may be 93 million miles away, but that does not stop its solar activity from affecting the Earth's atmosphere, a new study from Queen's University Belfast as found. The Earth's atmosphere is ...

This is the conclusion of researchers from the University of St Andrews, Scotland, who found that the positively charged ions in solar flares—one of the two key components of solar plasma—can be ...

The sun has emitted a powerful solar flare that has the capability to interfere with technology on Earth. The explosive burst of radiation peaked on the evening of June 17, matching the intensity of ...
