Northern Lights Illuminate European Sky
#Cosmoread: On March 7, a NASA satellite caught a glimpse of the spectacular aurora borealis phenomenon, as seen from your backyard stargazers across northern Europe spectacular colors green and pink.
Visible Infrared Imaging Radiometer Suite (VIIRS) sensor using a low light, Suomi NPP satellite captured a view of the Aurora, Iceland, England, Scotland and Norway streaks disclosed above. Sensors such as airglow, gas flares, city lights glimmering detects signals, and the moonlight reflected from the sensor but does not distinguish between different colors of light, the aurora appears white. By NASA Earth Observatory image was released this week.
The aurora borealis, also known as the northern lights, the charged particles from the sun interacting with Earth’s magnetic field is a vivid demonstration. The charged particles are created when massive explosion in a steady stream of protons and electrons, known as coronal mass ejections from the sun’s surface stream, called the solar wind and the Earth rush. The solar wind slams into Earth’s magnetic field, causing disturbances in the atmosphere.
The storms particles from the sun are already trapped in the magnetic field around the earth energize. The electrons then race down the Earth’s magnetic field lines and the accident at the height gases. They gases oxygen and nitrogen molecules in the gas molecules is energy, which will provide exciting electrons. Short bursts of energy – – as light as the excited electrons return to their normal state, they release photons. A green gives off oxygen and nitrogen produces blue or red.
But it is not often that you see these psychedelic lights are in the south of Scotland. According to NASA, the geomagnetic storm, a G3, or “severe” NOAA-scale geomagnetic storm level, color the night sky as a result of a very broad swath of northern Europe reached over.
