With all the exciting solar activity lately, NASA’s Goddard Space Flight Center shared this helpful tutorial about the vocabulary of space weather on their Facebook page. Now you can tell your CMEs apart from your solar flares.

It's decently likely that, sometime in the future, a major solar storm will hit Earth, wreaking havoc on our infrastructure and crippling our satellites. But there's a more long-term danger: space could become too dangerously radioactive to stay there.

A brown dwarf located 47 light-years away is behaving very strangely. The would-be star's brightness is constantly changing, fluctuating by as much as 30% in just eight hours. This could be an atmospheric disturbance that dwarfs Jupiter's Great Red Spot.

How accurate do you expect your local weather report to be? Honestly, I'll believe their predictions up to 48 hours, but anything beyond that is pushing it. Now it looks like our ability to predict sunspots is now at that same level, giving us valuable warning time for people in space, and infrastructure on the…

This picture was taken by a NASA solar observatory yesterday, and it shows one of the biggest explosions we've ever seen on the sun. For perspective, look at the upper left corner. There's a little circle the size of Earth.

The sun blasted mass quantities of plasma into space a few days ago, and the "coronal mass ejection" is headed straight for Earth. Which means we're about to get some incredible aurora displays.

Worried about solar winds and space weather interfering with global cell phone reception, possibly plunging the world into a new Dark Ages? Apparently, so is NASA: they've designed a satellite for the sole purpose of monitoring space weather.

Fueling fears about the dimming sun, scientists are predicting that the current solar cycle is not only running a year or so late, but will also be the weakest cycle since 1928. Solar disaster!
