GREGOR's high-resolution FAST IMAGER happened to scan the sunspots in active region NOAA 14274 just 30 minutes before the ...

A vast, magnetically tangled sunspot has rotated into direct view of Earth, raising the prospect of powerful solar eruptions ...

A new study led by Southwest Research Institute (SwRI) links quasi-periodic pulsations (QPPs) in solar flares to dynamic ...

It's been a busy year on the sun, as it officially entered the peak of its roughly 11-year cycle of activity, known as solar maximum. In 2024, the sun launched over 50 X-class solar flares — the most ...

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, ...

Flickering coronal loops in the Sun's outer atmosphere could act as an early warning system for solar flares, according to new research. Reading time 2 minutes Intense solar flares—sudden bursts of ...

The sun is not a static, tranquil sphere of gas, but an active, turbulent star with magnetic fields that twist and snap in powerful eruptions. Among the most striking and energetic of these eruptions ...

The sun has a bone to pick with Earth — and it’s not done yet. A colossal solar storm just zapped the daylight side of the planet, causing global blackouts and knocking out radio signals across Europe ...

There were significantly more X-class solar flares in 2024 than any other year for at least three decades. The arrival of solar maximum was a key reason for the spike, but other factors were also at ...

A high-powered solar flare erupted from the sun last week, causing a major radio blackout in Europe and Asia. The eruption happened at 3:25 a.m., meaning that the sun wasn't in the Texas sky at the ...

Scientists from the University of St Andrews have discovered that ions in solar flares can reach scorching temperatures more than 60 million degrees—6.5 times hotter than previously believed. This ...
