Rare Red Aurora Makes a Veteran Astronaut Do a Double-Take

Even after months in space, there are still things that will surprise you. Astronaut Scott Kelly tweeted a photo Monday of a curiously red aurora he spied from the International Space Station. Describing the phenomenon as "spectacular," the red aurora was a rare treat as it typically appears only during an intense solar storm. Kelly also tweeted a video of the aurora turning from red to purple as he orbited around the Earth. He is currently two months into his year-long mission aboard the ISS, and we can only expect more spectacular photos to come. A G4, or "severe," solar storm was underway when Kelly took these images. A similar solar storm is anticipated to affect the Earth beginning on Wednesday, which could result in more dazzling aurora displays.
