Solar Jet Hunter

Join the hunt for solar jets — enigmatic bursts of energy from our own star — the Sun!

Get Started!

In the workflow "Jet or Not", you can visualize short videos of some region of the Sun and tell if any jet is happening there.
In the workflow "Box the Jets", we ask you to make annotations in the video, by marking the base of the jet and drawing a box around it! This workflow will appear in a few days, once jets have been found by volunteers in the first workflow.

I am very intrigued by the mystery of how the solar system is filled with energetic particles. I think solar jets are a good way to get solar particles out into the solar system, so, this project presents an important opportunity for testing this idea.

About Solar Jet Hunter

The Solar Dynamics Observatory (SDO) has spent more than a decade collecting data from the Sun. One of the Sun's most enigmatic behaviors is its bursts of energy, which can take the form of jetted material like water spewing from a hose. In order to understand how the Sun forms jets, we need to examine the SDO data to figure out when and where the solar jets occurred on the Sun.

While some progress has been made by developing algorithms to identify jets, these programs are not accurate enough to provide sound research data. A far more effective tool for finding interesting features on the Sun is the human eye! We need your help to locate solar jets.
