The Seen Infrared Imaging Radiometer Suite sensor on the NOAA-NASA Suomi NPP satellite captured this picture of the aurora borealis, or northern lights, over western Canada at 3:23 a.m. MST (5:23 a.m. EST) on November 5, 2023.
Auroras are colourful ribbons of sunshine showing in evening skies, incited by a powerful geomagnetic storm in Earth’s magnetosphere. A number of coronal mass ejections from the sun despatched a surge of charged particles towards Earth. After colliding with Earth’s magnetosphere, some particles trapped within the magnetic field are accelerated into Earth’s higher ambiance the place they excite nitrogen and oxygen molecules and launch photons of sunshine, often called the aurora.
Should you like watching shows equivalent to these, you may help scientists verify aurora sightings to allow them to analyze and embrace them in space climate fashions.
