Strongest solar flare of 2025 erupts from sun, ... invisible magnetic field loops that arc around the sun. Therefore, the flares can be considered as two parts of a single explosion. ...

A blazing X2.7-class solar flare erupted from sunspot AR4087 early Tuesday, hurling a scorching wave of plasma and charged particles straight at Earth. NASA/SDO.

Starlink satellites appear to be at the mercy of the Sun's whims. A recent study reveals a link between their lifespan and ...

Solar flares are measured on a scale of A, B, C, M and X, with each class being 10 times more powerful than the previous. The most powerful solar flare of this solar cycle—of which we are ...

The most powerful solar flare of this solar cycle so far occurred on October 3, hitting X9.0-class in strength. Today's X9 (R3) flare was prolific, but impulsive (imagery courtesy of jhelioviewer).

Both astrophysicists — Lindsay Glesener from Minnesota and Sabrina Savage from Alabama — are trying to find out more about solar flares during the five minutes the rockets will arc above ...

Solar flares are closely related to another solar phenomenon called a coronal mass ejection, or CME. Where there's a flare, there's likely to be a CME, just like where there's smoke there's fire.

What we were actually seeing was a giant arc of solar plasma extending far enough away from the Sun's surface as to be visible around the edge of the Moon. These arcs are typically called filaments.

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 ...

NASA says that Solar Cycle 25 is already exceeding predictions. As a result, the space agency says that solar flares will increase over the next few years. And that it could cause some problems ...

Strongest solar flare of Cycle 25. At just after 8 a.m. EDT, on Thursday, October 3, sunspot AR3842 blasted out another intense solar flare. This one ranked as X9.0-class, making it the strongest ...

On Jan. 22, at around 10:30 p.m. ET, the two solar flares exploded at almost the exact same time from sunspots AR3559 and AR3561, which, at the time, were separated by around 310,000 miles ...
