During its flyby, Parker snapped some amazing close-up images of the Sun, which NASA finally released to the public yesterday. The images, captured by the probe’s Wide-Field Imager for Solar Probe, or ...

A fiery X2.7-class solar flare that erupted from ... The storm blasted out at 4:25 a.m. ET and registered as an R3-level event — strong enough to disrupt high-frequency radio signals and ...

A groundbreaking new mission may soon allow scientists to study the sun’s corona with unprecedented clarity. The Moon-Enabled Sun Occultation Mission (MESOM), a proposal from a group of researchers ...

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 ...

Solar flares measured around X1 — like the May 13 and 14 events — indicate strong flare intensity. An X10 flare is described as as a severe event, according to NOAA.

"Solar activity reached high levels. An X3.3/sf flare was observed at 24/0357 UTC from Region 3869," NOAA's Space Weather Prediction Center said in a forecast discussion, "as well as an ...

The sun unleashed a massive X-class solar flare -- the most powerful it can generate -- on Tuesday evening that has the potential to pummel our planet with a powerful geomagnetic storm this weekend.

The 2001 sunspot peak came only a few years before the famous 2003 Halloween storms, when an X45 solar flare and G5 geomagnetic storms were recorded and power outages occurred in Sweden.

The northern lights may be visible along a stretch of northern states Tuesday night, and a recent solar flare could heavily disrupt radio frequencies this week, according to a National Oceanic and ...
