The Scientists Discovered The Real Cause Of Northern Lights

The Northern Lights represent a spectacular phenomenon that can be observed in the northern regions of the planet. The colorful lights that appear and “dance” on the night skies can be admired from the polar regions but also from Canada, Alaska, Finland, Sweden, and Norway. Recently, the scientists discovered the real cause of Northern Lights.

The Northern Lights, also known as Aurora Borealis, are green and blue, in general. Rarely, they can be yellow, red, or purple.

The Aurora Borealis is believed to occur when the Sun’s charged particles impact with the gas molecules from the Earth’s atmosphere causing them to light up.

This theory, however, has never been observed practically and, therefore, is not yet proven.

The first practical observation of the Northern Lights phenomenon

Recently, a group of researchers was able to use satellites and accurate measurements tools to observe and calculate how exactly do the Northern Lights appear.

The scientists found out that the Earth magnetosphere is involved in the Northern Lights phenomenon. Accordingly, the electrons interact with the plasma waves in the magnetosphere causing the release of the stored solar wind energy.

More specifically, the plasma waves cause electrons to scatter, an event that makes particles to shower in the Earth’s atmosphere leading to Northern Lights occurrence.

A high-tech sensor on a Japenese satellite may return important information

It is hard for the researchers to say which electrons are involved in this phenomenon. However, to find an answer to this, too, they’ve already placed an advanced electron sensor on the Exploration of Energization and Radiation in Geospace (ERG) satellite. The satellite has been launched by the Japanese space exploration agency.

The researchers hope the advanced electron sensor of the satellite will send back precious set of data about the electrons that cause the Northern Lights phenomenon, also known as Aurora Borealis.
