ISS tool spot shooting blue light jets upwards


Do you ever wonder about the many experiments taking place at the International Space Station (ISS)? What do astronauts study in this orbital laboratory?

Okay, a lot of things but one of them is weather: especially weather-like events that cannot be seen from Earth. They are called Blue jets, and fictitious dwarfs (due to low emission for light and very low frequency due to electromagnetic pulse sources), and their monitoring is possible by a European instrument called the Atmosphere – Space Interaction Monitor (ASIM) Observatory.

The ASIM, installed in the space station in 2018, consists of a collection of optical cameras, photometers and an X and gamma-ray detector to detect electrical discharges from weather events that can only be seen in space. Understanding these weather events is not only important for understanding the Earth’s weather, but also the concentration of greenhouse gases in the Earth’s atmosphere.

What are the elves and blue jets?

But what are blue jets and elves? Blue jets, as their name suggests, are blue electric currents that do not go towards land, but shoot upward into space. As the pictures show, they are quite beautiful to see.

Elves, on the other hand, are light emitters that appear in the ionosphere as rapidly spreading rings.

Both the elves and the blue jet were spotted by ASI on February 26, 2019, near Nauru, a small island in the central Pacific Ocean. He is now described in a published paper Nature On January 20, 2021. The study describes these events, capturing their awe-inspiring beauty even without the use of pictures.

If you are a fan of space phenomena then this is definitely worth reading. It is a sign of all of us still exploring on our precious planet.

“This paper is an impressive highlight of many new developments. ASIM is watching with thunder and shows that we still have a lot to learn and learn about our universe,” said Astrid Orr in a statement Physical Coordinator for Human and Robotic Spaceflight. .
