The first of two coronal mass ejections have slammed into Earth's magnetic field and space weather forecasters predict this rare one-two punch could result in 'supercharged' auroral displays. Continue reading →
Space weather forecasters have confirmed that Wednesday's solar flare also generated a coronal mass ejection that's now racing toward Earth. This is the second Earth-directed CME in two days. Continue reading →
In recent weeks, the International Space Station crew have been treated some some mind-blowing auroral displays. Here are some of our favorite moments.
