What are Picoflare jets?

Sept. 9, 2023

Researchers studying the findings of the Solar Orbiter Aircraft, a joint mission by the European Space Agency and the U.S. space agency NASA, recently announced that they have detected picoflare jets from the sun’s outer atmosphere.

About Picoflare jets:

These small-scale picoflare jets were observed within emissions from the coronal hole under observation.
They lasted only a few dozen seconds, scientists calculated that they provide enough energy to supply a considerable fraction of solar winds.
These jets from the sun are named so because they carry approximately one-trillionth the energy of the largest flares the sun is capable of producing,
Significance:
- The discovery is important because strong gusts of solar winds, while creating beautiful auroras in polar areas, are capable of disrupting the earth’s magnetic field as well as damaging electronics in satellites in space and in circuits on the ground.

Key facts about Solar Orbiter Aircraft

It was launched in 2020 and will take images of the Sun from closer than any spacecraft before.
It contains six remote-sensing instruments and four sets of in situ instruments.
Objectives
- To observe the Sun’s 11-year cycle of rising and subsiding magnetic activity.
- To study the upper layer of its atmosphere, the corona.
