Solar storms: Five key facts
This weekend's solar storm brought spectacular auroras over a big part of the Northern Hemisphere. Here are five facts about these dazzling – and sometimes dangerous – eruptions from our sun.
-
Are solar storms hazardous? It depends on how fast they move.
Studying the speed of particles in solar storms may help predict dangerous impacts: the slower the particles' speed, the higher the risk, say NASA scientists.
-
Huge solar eruption could make for dazzling northern lights (+video)
A giant solar eruption may bring an exceptional weekend northern lights display for those as far south as California and Alabama, a NASA scientist says.
-
Humongous solar flare erupts in our direction (+video)
The strongest solar storm of the summer so far could send a wave of charged particles toward our planet that could supercharge northern lights displays, NASA scientists say.
-
Sun continues to spew
The sun continues its active streak this week, spitting out yet another solar flare from the same region that produced two powerful eruptions this week.
-
Solar storm could become severe 'bell ringer' in next 24 hours (+video)
Solar storm forecasters say the particles disgorged in a massive solar flare could strike Earth in a particular way, which would make a currently moderate solar storm more severe.
-
Biggest solar storm in years now bombarding Earth (+video)
The two huge solar flares that erupted on the sun on Tuesday have produced a wave of charged particles that are now glancing off our planet's magnetic field.
-
Solar flare races towards Earth, expected to cause disruptions to Earth's magnetic field
The largest solar flare in years is hurdling towards Earth at 4 million mph and is expected to hit early Thursday morning.
-
Will the solar storm disrupt power grids? (+video)
The sun has hurled a cloud of charged particles in our direction, potentially disrupting satellites and inducing current in our power grids.
-
Two powerful 'X-class' flares erupt on sun (+video)
The sun unleashed two extremely powerful flares Tuesday. NASA tentatively says that particles from the solar storms are probably heading in Earth's direction, but will likely deliver a glancing blow at most.
-
Space station dwellers safe from massive radiation storm
NASA scientists also routinely monitor space weather conditions in order to protect astronauts and hardware in orbit from harmful radiation, and today's solar storm is no exception, agency officials said.
-
After solar flare, massive storm speeds Earthward
A solar flare Sunday triggered an outburst of solar material that should hit Earth Tuesday. The disturbance could lead to voltage swings on some power lines, as well as stronger northern lights.
-
Massive eruption on sun to shower Earth with radiation
A barrage of charged particles triggered by this morning's solar flare is expected to hit Earth tomorrow at around 9 a.m. EST.
-
Enormous solar outburst could dazzle your weekend
Auroras may dazzle more people than usual this weekend as Earth receives a glancing blow from an enormous solar outburst that erupted on Jan. 19.
-
Northern lights: Huge solar flare may trigger Saturday night show
Northern lights show this weekend? A big solar plasma wave is heading toward Earth, and may create Northern lights or aurora borealis display by Saturday night.
-
Northern lights: Aurora borealis astounds skywatchers
Northern lights: Traditionally, only skywatchers in high-latitude locations can see aurora borealis, but during strong solar weather events, they can be visible to observers at lower latitudes.
-
Solar storms: Two breakthroughs could lead to better warnings
The solar storms that cause blackouts and damage satelites have always been hard to predict, but two new methods of monitoring them could lead to much more accurate forecasts.
-
Solar storms: New solar flare is largest in years
Solar storms have been picking up since 2008. A new flare Tuesday is the biggest in several years and is part of a pattern of solar storms scheduled to last until 2020.
-
Geomagnetic storm activity increasing, catastrophe looming?
Geomagnetic storm: A true monster storm has the potential to wreak havoc on a global scale, knocking out communications systems, endangering satellites and astronauts and causing perhaps trillions of dollars in damages.
-
Solar Flare: A Northern Lights show for North America?
Solar flare - one of the biggest in four years - shot from the sun on Sunday. Scientists predict that a solar flare of this size - and traveling toward Earth - could produce a dramatic light show. Did it?
-
3D sun images provide early warning of hazardous space weather
3D sun images: With its twin STEREO space probes, NASA can now see the sun in 3D, offering increased protection against solar storms.
-
Missed Tuesday's northern lights show? Another is on its way.
For folks along the northern rim of the US, a second chance to see the northern lights will come when another solar outburst hits Earth Wednesday or Thursday.
-
Where the best seats will be for northern lights after solar eruption
Plasma from the sun slammed into Earth's magnetic field Tuesday afternoon. Here's a look at what kind of northern lights show the collision will put on.
