What scientists thought caused certain classes of northern lights is not what causes certain classes of northern lights.

In a landmark study that has toppled what scientists know about the night sky, UAlberta physicists Robert Rankin and Dmytro Sydorenko found that the ionospheric feedback instability (IFI)—the mechanism thought to be the cause of certain types of northern lights—not only doesn’t cause northern lights, it may not even exist at all.

NASA and NOAA satellites have provided data on Maria as it strengthened into a major Hurricane headed toward the Leeward Islands. NASA's Aqua satellite provided an infrared look at Maria that showed cooling cloud top temperatures and NOAA's GOES satellite provided an animation of imagery that showed the storm developing and strengthening. The GPM satellite found "Hot" towering clouds that indicated strengthening was occurring before Maria became a major hurricane.

Visible imagery from NASA's Aqua satellite showed Tropical Depression Lee as a weak swirl of clouds around its center with most of its clouds and thunderstorms pushed east of its center.
