NASA discovers that a new twilight is shining on the sky of Mars, but it is forming on the side of the planet, and it is difficult to see it
The Maven spacecraft has observed mysterious rays of sun in the hydrogen gas of the upper atmosphere of Mars.
Unlike the Earth's equatorial twilight caused by electrons, this optical event on Mars is due to the flow of protons.
Scientists studied this phenomenon using the UltraViolet Spectrograph Imaging Instrument, installed on the Maven Probe, where the tool revealed situations where ultraviolet light shines for hours [19659002ThishappenedwhenthesolarwindbadyzerintheMaveninstrumentrecordedanincreaseinprotonsfromthesewinds
According to NASA, protons are able to act this way by "flying" the electrons on their path. "As it approaches Mars, the protons that come with the solar wind become neutral atoms by stealing electrons from the outer edge of the mbadive clouds of hydrogen surrounding the planet," he said. said. Red. "
Dejan continued:" The shock The arc can only convert charged particles, so these neutral atoms will continue in their path. "
According to the experts, these unusual proton impurities occur more frequently on Mars than on Earth, mainly because of the strong magnetic field of the Earth.
When this phenomenon occurs in the Earth, in rare cases, it can be seen in small areas near the poles, but on Mars, twilight can occur anywhere, according to NASA.
It is also common in Venus and Saturn's Moon, Titan, who miss the magnetic fields
