New work helps to codify the cause and properties of "Steve," an aurora-like phenomenon documented by citizen scientists as it streaked across the sky in western Canada.

A minor solar storm will reach Earth Wednesday (March 14) and could supercharge the planet's auroras, making them visible from the northernmost parts of the U.S., space weather officials say.
Thanks to a solar storm, the northern part of North America may see a dazzling auroral display tonight.
A moderate solar flare early this week has generated charged particles that will light up the atmosphere — and could impact power grids and satellites — as early as Thursday.
The origins of "pulsating auroras" — intense flickering displays of light high up in Earth's atmosphere — are now revealed after a decades-long hunt, a new study finds.
The sun may be dimming, temporarily. Don't panic; Earth is not going to freeze over. But will the resulting cooling put a dent in the global warming trend?
New research may have identified an early warning sign of how powerful explosions from the sun might get, shedding light on whether they could damage communication satellites and power grids.
A long-lost-but-recently-rediscovered NASA satellite appears to have a fully charged battery and is "in good shape" overall, the agency said in an update yesterday (Feb. 5).
An amateur astronomer appears to have made contact with the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) satellite, which lost contact with NASA in 2005.
Two satellites, one carrying a NASA science instrument, are safely in orbit despite an anomaly with their Ariane 5 rocket during launch, Arianespace officials say.
A new NASA mission, the first to hitch a ride on a commercial communications satellite, will examine Earth's upper atmosphere to see how the boundary between Earth and space changes over time.
