The first astronauts who set foot on Mars can expect a unique view. The latest research shows that the aurora is formed on the entire Red Planet, not just around the polar circles.
– On Mars, we have seen a new type of aurora borealis. It is located in regions where at all there is no magnetic field – said Dave Brain, co-author of the study.
particles fall into the atmosphere
The fact that on Mars there are auroras, scientists They announced in March. They explained that billions of years ago the planet was no longer protective magnetic field, which particles fall directly into the atmosphere.
– electrons responsible for causing the Martian aurora dysponowały energy load 100 times greater than the spark in your home socket. That they allowed the deep penetration of the planet’s atmosphere – Belgian researcher explained Arnaud Stiepen cosmos.
Satellite Mars
The data that have served this discovery, gathered MAVEN spacecraft. It is located in orbit around Mars and is an artificial satellite of the planet. The data initially served the professionals to discover that the Martian atmosphere “blew out” the solar wind.
The important role
Mars, unlike Earth, does not have a magnetic field that encompasses the entire planet. This affects its atmosphere. The magnetic field protects against solar radiation, which in excessive quantities would be harmful for us.
