A cannibal coronal mass ejection from the sun, which overtook and combined with another CME, is due to hit Earth.
In the wake of a powerful plasma ejection from the Sun's surface, the Northern Lights are forecasted to be visible over parts of the United States.
The U.S. Space Weather Prediction Center has upgraded its geomagnetic storm watch from moderate to strong as a group of CMEs approaches.
The eruption, known as a coronal mass ejection, may cause a minor geomagnetic storm and some active auroras.
A strange aurora phenomenon, dubbed STEVE (Strong Thermal Emission Velocity Enhancement), has been spotted over Canada.
Cosmic rays recorded in the atmosphere above California have dropped sharply thanks to the sun's increasing activity.
A huge "full-halo" solar ejection is headed straight for Earth, and will result in spectacular auroral displays on July 23.
A surge of solar wind following a coronal mass ejection from the sun is due to hit the Earth's atmosphere, creating a beautiful aurora display.
Train signaling might be disrupted by solar flares and other space weather, leading to delays or even crashes.
A solar storm as large as four planet Earths has been recorded hovering above the Sun's surface.
The flare erupted from the sun on Wednesday night, and scientists are working to determine if a coronal mass ejection (CME) is headed towards us as a result.
The number of sunspots—areas where solar flares and charged particles may erupt from—appears to be ahead of forecasts.
Solar activity is set to become more frequent in the coming years as the sun's 11-year solar cycle is yet to reach its peak, which is measured by the number of observed sunspots.
Footage of the Northern Lights was captured by Spencer Dant who was flying over Alaska.
The stunning phenomenon, also known as aurora borealis, could be seen in states including South Dakota and Montana on Wednesday night as part of a geomagnetic storm.
States from Oregon to Pennsylvania could see spectacular auroras thanks to a huge eruption of plasma from the sun.
Two solar eruptions are heading towards Earth and could hit us by Thursday, said the Space Weather Prediction Center.
An eruption of plasma from the sun prompted warnings of possible satellite disruption and of auroras being visible in Michigan and Maine on Monday morning.
Solar interference with Earth's magnetic field may spark northern lights over Alaska and Canada.
The energy, known as a coronal mass ejection (CME), erupted from the sun's surface on March 7 and might deliver a glancing blow to our planet.
Had the explosion occurred today, it would have been "catastrophic" for satellites, aircraft, and computers, said scientists.
Imagery of the eruption was captured by the Solar Orbiter spacecraft's "Full Sun Imager," which was designed to observe the full solar disc, even during close flybys of the sun.
The storm, caused by a huge release of energy from the sun in the form of a coronal mass ejection, might also interfere with some electronics.
Santa will have some extra illumination to guide him over the North Pole this year as charged particles from the sun potentially enhance the aurora borealis.
The colorful auroras showed up from Scotland to Canada after scientists warned of potentially disruptive events following the space-based phenomenon.
Solar storms have the potential to knock out power systems, and some warnings have been issued because of this burst of activity.
Several sheriffs and a New York City council member have said they plan to ignore the governor's new rules, calling them unconstitutional.
The state's health department said in press release that the new high in daily cases is "concerning."
Researchers identified unusual solar activity around 660 BC in astrological records they then matched to tree ring data.
