Without magnetic fields, Venus still has an aurora

Scientists have always assumed that aurora phenomenon cannot appear on Venus because the planet does not have an Earth-like magnetic field, but the results of the recent study are completely contrary to the above.

The researchers were surprised to find that the magnetic field effect that creates an aurora under the Earth could create giant magnetic foams that surround the Venus - the planet, which has no magnetic field.

Essentially beautiful auroral and northern polar images on earth are formed from the colliding and cohesive forces of magnetic fields, also known as the 'magnetic reconnection' process , which causes transformation. Strong magnetic energy into kinetic energy and thermal energy.

Previously, scientists believed that magnetic reconnection only appeared on planets such as Earth, Mercury, Jupiter and Saturn. The magnetic field on these planets refracts with charged particles in the solar wind, then radiates to the shield surrounding the Earth or magnetosphere.

Meanwhile, the magnetic reconnection process can occur right inside the magnetosphere, causing aurora and magnetic storms.

On the hidden areas of the planets where the solar wind cannot blow, the magnetosphere at these places is stretched out or the "magnetosphere" . Although there is no magnetic field, Venus has a magnetosphere because it is formed under the interaction of solar wind and the ion layer - the upper region of Venus contains charged ions.

After using research data from the European Space Agency's Venus Express spacecraft, the researchers were surprised to find that the magnetic reconnection process happened right in the magnetosphere. With Venus's initial result was the formation of a 3,400-km plasma foam that existed for 94 seconds.

Aurora extends below the Earth

Tielong Zhang, a scientist at the Institute of Science (Austria), said: 'The intensity of Venus and Earth's plasma currents is the same, despite the fact that these two planets have a completely magnetic environment. different'.

The discovery is also an important clue to help researchers explain the emergence of mysterious light at night on Venus.

'Over the past decades, many space observation devices have detected faint light on Venus - many images are claimed to be aurora phenomenon. But this claim is completely unfounded because Venus doesn't have a magnetic field , 'Zhang said.

Therefore, the most definitive answer to the mysterious light that appears on Venus is the magnetic reconnection process that occurs in the planet's tail region, as well as explaining the tail image. The comet is glowing and the head is not.
