Scientists observe aurora across Mars
In the United Arab Emirates’ Mars mission, scientists have spotted a ‘worm-like’ aurora that stretched halfway across the Red Planet. The discovery of discrete curvy auroras has come from observations from the Hope orbiter. Besides these, lights are shining high in the atmosphere. which has been at work since February 2021. There is only a patchy magnetic field on Mars thus making auroras tough to track down. Hope assisted with better observations by the locals and nighttime aurora varieties that avoided other missions.
Martian auroras are found across half the surface of Mars, check details here!
But the other types of lights are not there near the scale of the new sinuous discrete auroras. These auroras covered almost half of the planet. The observations at that scale required Hope’s unique ability for the snapshots of the whole disk of the thin Martian atmosphere in action as said by the officials.
Different factors leading to different auroras
Hessa Al Matroska said that they didn’t expect to see such massive effects of the aurora. Reasons for the occurrence of Martian auroras can be a variety of factors. For instance, the discrete aurora occurs above magnetic minerals in the planet’s crust, while the interactions between the solar wind lead to proton auroras. A solar wind is a constant stream of charged particles that flows off our sun, and hydrogen in the thin Martian atmosphere. The newly identified sinuous discrete aurora seems more similar to the diffuse aurora. Intense solar storms cause them.
Hope collected all its observations in ultraviolet light as a solar storm struck Mars. Such solar storms may occur more frequently in the coming years leading up to 2025. At that time, the sun’s 11-year solar cycle is predicted to peak. Scientists hope that better understanding of the appearance of the sinuous discrete aurora and its features can enhance their knowledge and understanding of the solar wind and how the Martian magnetism affects the planet.
New information from Emirates Mars Mission
Starting from the first observations of the discrete aurora, we continued seeing new and incredible patterns of aurora. They open up new insights into the interactions of charged particles in the Martian atmosphere, as said by Al Matroushi. There is a lot of new information that we are getting here for the EMM [Emirates Mars Mission]. This will help the science team to work with it. More information about this might be hidden in archival data from other missions. Information was collected by the long-running European Space Agency’s Mars Express and NASA’s MAVEN (Mars Atmosphere and Volatile Evolution) spacecraft. This was to observe the Red Planet’s atmosphere.
The discovery of sinuous discrete aurora was shocking. It made us scratch our heads and go back to the drawing board. Rob Lillis is a planetary scientist at the University of California, Berkeley. He is working on the Emirates Mars ultraviolet spectrometer instrument. In a statement, he said that we don’t have solid explanation for our ideas of why we are observing intense aurora of this shape and at planetary scales.
FAQS
1. What did scientists spot on Mars?
Scientists with the United Arab Emirates’ Mars mission have spotted a ‘worm-like’ aurora stretching halfway across the Red Planet.
2. From where we’re the auroras arising?
The discovery of “sinuous discrete” auroras, or shining lights high in the atmosphere arising from solar activity interacting with magnetic fields, came from observations from the Hope orbiter, which has been at work since February 2021.
3. How is the discrete aurora caused?
The discrete aurora, for example, apparently occurs above magnetic minerals in the planet’s crust
