The sun unleashed a mid-level solar flare on April 2, an event that was captured on video by NASA's Solar Dynamics Observatory.
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.
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.
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.
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.
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 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.
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.
The largest solar flare in years is hurdling towards Earth at 4 million mph and is expected to hit early Thursday morning.
The sun has hurled a cloud of charged particles in our direction, potentially disrupting satellites and inducing current in our power grids.
