The
northern aurora borealis paints the night sky with a palette of smooth color
above one Nebraska city.
Skywatcher
Mark Urwiller caught this stunning view of the aurora borealis, also known as
the northern lights, from his vantage point five miles outside Kearney, Nebraska. Urwiller photographed the light show the evening of May 14, 2005, though
NASA released the image on May 18.
Auroras light up the sky when
charged particles from the Sun, also known as solar wind, enter the Earth’s
magnetic field. The wind accelerates electrically charged particles already
trapped within the magnetic field. The high-speed particles crash into the
Earth’s upper atmosphere over the planet’s polar regions, emitting a
multicolored glow.
