Astronauts aboard the International Space Station had a unique view of the vivid Aurora Borealis, or Northern Lights, which lit up the night sky around the Northern Hemisphere on Tuesday and Wednesday.
The result of a rare, severe geomagnetic storm that fortunately did not endanger ISS crew members or affect the station's navigation systems, the Aurora was visible as far south as Pennsylvania on Tuesday night.
NASA astronauts captured the first night of the spectacular Aurora displays, and shared these otherworldly images via Twitter:

In recent years, astronauts have posted numerous videos and photos of Aurora Borealis and Aurora Australis events.
